60 mins around 310W

I last did this on 3 Feb and quite liked it even though it gets tough towards the end. After a poor night's sleep and a crappy day at work I was in 2 minds whether to do a workout to day or not, but I guilted myself into it knowing that I need to keep working hard to gain/maintain fitness ready for the race season.

The session went almost exactly as before until my Garmin Premium HR strap started to play up after 35 minutes. I don't have a lot of luck with these and they normally fail after 4-5 months and this one was no different. I was unable to complete the 4mins x 320W interval at around 46 minutes and instead converted it into 2 intervals of 2 mins at 320W with a short recovery in between. I think my HR data at this point was correct as the recorded 167bpm is usually where my body starts to whinge and moan about the effort and I start to think about quitting.

The last interval is 1 min all-out. Today I managed 445W and I felt very ill and light-headed at the end.

The Hunted

I was going to do a roller session yesterday but after 20 minutes I stopped. Just didn't feel like doing it and I wasn't going to get much out of it. I've been feeling a bit throaty for the last couple of days coinciding with a selfish b'stard at work coughing and spluttering at an adjacent desk.

So today I planned a Sufferfest 'The Hunted' session which I found challenging and unachievable last time I did it. However, being an idiot I forgot that I was just unable to get to the end of the middle 20 minute session and had to back off. In a way this was actually a good thing because I went into the workout expecting to be able to compete it and probably tried harder as a result.



So, it went well through the first taster and then all the way through the 'middle 20' until I got to the section marked with the big red A (for Aaaaaaarrrgh!). With a high HR my body just said NO! and I had to stop, feeling quite miffed because I thought that I had completed this bit last time.

The last session was achievable, but I was really suffering on the 5x350W+ intervals at the end and was very pleased to stop and when I did I realised how hard I had been working; gasping for breath and my throat slightly constricted. I'm not asthmatic, but I think it was the same feeling.

So, I probably won't do this again for a long while. There are 2 hard bits that are too hard and the rest is too easy and really just foreplay waiting for the pain. It's quite like a race in that respect, but racing isn't necessarily the best way to increase fitness.

60 mins around 310W

Had a recovery day yesterday, did a bit of shopping, took some photos, drank a couple of glasses of wine, relaxed.

Today I wanted to work on intervals around 310W (FTPish) with shortish recovery intervals between as a result of a poor performance on Friday's 2x20 session. For some reason, and it's not just me, starting the second 20 of a 2x20 seem extraordinarily hard so I wanted to work in that area for a while.

About a month ago I devised the following interval set (with a 2 min recovery interval between each one) with 37 mins at or above 300W so this was the first time I'd tried it:

6 mins x 330W
5 x 300
4 x 320
3 x 310
5 x 300
6 x 310
4 x 320
3 x 300
1 min all out (achieved 408W)

Black=power, red =HR.


Any power variations through the intervals were me trying to manage my average power to ensure that I didn't overcook it too early in the session. Intervals 6 and 7 got my HR up to LTHR and I was suffering a bit towards the end of the 7th. The last 1 min interval was very hard and I did it on feel rather than looking at my power output, which probably explains why it rises throughout. At the start I was quite conservative and then allowed power to build throughout the interval, really whimpering and grunting by the end of it. It's no surprise that the slope of the HR rise for the last interval is so steep.

Overall the session was quite enjoyable and I can imagine being able to repeat intervals 5, 6, 7 and 8 to make it a longer session before hitting the final all-out interval.

Post-cold leg spinner

After 6 days of feeling too ill to train I was looking forward to getting back on the turbo tonight to give my legs a spin to make sure I'm over the cold and ready to train again. I am usually lucky with colds and don't normally suffer for more than a couple of days, so I was a bit concerned when I had to have a day off work because I didn't feel well enough to go in.

Today's session went quite well. Basically I just pedalled at a comfortable working level while I monitored my heart rate, keeping it below 165. As the 45 minutes passed I seemed to get stronger with power genty rising from around 250W to 290W and HR rising to 165. So, providing I feel OK tomorrow I'll be back into the groove with some intervals again.

It's a real shame to have lost a week of training, but as I'm not trying to peak for a specific race I suppose it doesn't really matter. After all, most other riders are just doing longer versions of what I did today as they build up their winter base fitness. Ah, the traditions of cycling!

While I was ill I ate everything and anything I saw. Loads of chocolate, carbs, fruit, cake. You name it, I shoved it in my gob. So I'm also back on my New Year healthy eating plan and trying to cut out the carbs and cheese and increase the protein.

Mike's Guide to Turbo Training


The aim of this post is to provide guidance on the use of Turbo Trainers for those that haven’t used them before or have recently started. It’s based on my personal experience; other views are available and might be more sensible.

warning: if you're really fat, pregnant, stupid, diabetic or have a history of heart attacks, please consult a medical expert before attempting anything written below or it may kill you.
In fact, just close the browser now and walk away, these are not the tips you're looking for.

The Real Basics

A turbo Trainer allows you to use your bike to exercise by producing a resistance to counter your pedalling force. There are many types of resistance units (wind, gel, magnetic, nuclear fission) and a huge range of prices, so I won’t discuss which is the best as there are lots of reviews on the internet. But remember that a turbo is for life, not just for the first 3 weeks of a new year so think about getting a good one. There are lots of good quality second hand ones being sold by people who didn’t follow the kind of golden advice below and have given up on their dreams, so the classifieds may be a good place to get a lightly worn uber-trainer for little money.

What you’ll need. Other than the bare minimum of a bike and a turbo, there are various additions you may wish to consider to make your turbo session more enjoyable, or less horrible, depending on how you feel about turbo training. Some of these are physical things, some are mental things…

Physical things you need

The right environment. You will sweat on a turbo so make sure you have an area where you can work without worrying about sweating on your new carpet. Your bike will probably shed a small amount of chain oil too and can be quite noticeable on a cream Wilton. It’s good to have a surface nearby to put your‘ gubbins’ on so you don’t have to dismount. Kitchens, garages or even outside are good places to do a workout. Your mum’s living room is a bad place. Plan for success.

A drink. Particularly for longer sessions, you’ll be glad you prepared a cool refreshing drink to sip between the intervals. The most obvious side-effect of a good turbo session is the pool of sweat under the bike when you finish so staying hydrated is very important.

A towel. I like to have a towel draped across my handlebars to remove the sweat from my face. While it’s a great feeling to know you’re working hard enough to leak like a sieve, it’s also very nice to not have the rivulets of salty sweat running into your eyes. Riders who want to look more‘continental’ may consider a headband as well.

Entertainment/distraction. 60 minutes on the turbo sounds great when you’re sitting surfing the internet buying the thing. Once you’re through the first few sessions you’ll very quickly start to tire of the whirring noise, and the sweating, and the burning in your thighs. I use a complicated series of distraction techniques to make my turbo time less horrible including loud dance music and YouTube clips of the Tour De France or the European Spring Classics. If you’re using a laptop it’s best to use a mouse rather than a touchpad (due to the sweat) and have everything ready to go before you start. The entertainment should not distract you from your planned session (more on that in a bit), but it should enhance the experience. You will not be able to read a book or magazine on the turbo. If you can read on the turbo, you’re doing it wrong.

A big fan. I’m not talking about getting your loved-one to cheer you on, I’m talking about a remote controlled 30+ inch industrial fan to blow refreshing cooling air over you to reduce the sweatiness and keep your temperature under control. I’m too tight to spend money on a fan, but lots of people swear by them. I tend to open as many windows as possible to make sure there is some airflow across my sweaty back.

Loved-ones. If you’re turboing correctly you won’t want to spend your precious time discussing ‘trivia’ with somebody. Explain to likely distractors that you need some ‘turbo time’ and would prefer to not be disturbed. While your husband/wife/girlfriend etc is being considerate by trying to tell you about what that bitch Julie said to her at work or wanting to discuss what you want for dinner, you’re unlikely to be able or willing to properly engage in the discussion while you’re turning yourself inside-out on the fifth interval of a set of six. You’re likely to swear at him/her. If you find you are regularly disturbed during your turbo time you could return the favour and ruin something they enjoy.

Clingfilm. As a cheapskate I use clingfilm on my bars to stop them getting sweat-soaked and smelling bad for the rest of the year. If you turbo with a bike computer it’s also nice to stop the sweat dripping off your nose and into the delicate electronics of your so-called waterproof electronic device. Clingfilm works on touch-screens and laptop keyboards too.

Minimal clothing. On the turbo I wear shoes, socks, a heart rate monitor and tiny shorts. With a headband I look like a 1970’s German fitness instructor, so I save that for special days. It’s nice to have a t-shirt to hand for the warm-up and cool-down, but I wouldn’t plan to be wearing it when you’re putting down the power.

Shoes. Cycling shoes are best for transferring your power through the pedals as their solid soles will stop your foot flexing which may become uncomfortable after a while. Clipless pedals or toe clips allow you to use more of the pedal stroke to transfer power. Flat pedals will do if you don’t have anything better. Oh yeah, and your shoes will get sweaty and may start to smell.

A method of recording your efforts. Whether it’s an expensive powermeter or a cheap cycle computer, being able to record your efforts and improvements is essential. If you feel like you’re getting fitter it’s great to have evidence to back it up. If you’re not improving, it’s time to change your workouts so that you do improve.
 
Mental things you need

A target. Setting targets will allow you to have a proper plan and give you the determination to complete it. Want to lose weight? Want to win races? Want to get away from ‘The Antique’s Roadshow’? Whatever, have a target and record your progress towards it and make sure your targets are specific, realistic and achievable. At 45 you’re not going to shed 40 kilos and win the British Road Race Champs next year, so don’t demoralise yourself by thinking you can then realising you can’t. A good example of a target is something like: By 1 June I will be able to ride for 60 minutes on the turbo at an average speed of 18 mph. This allows you to progress towards the target and monitor your progress. A bad example of a target is something like: I want to get fitter. After 2 days you’ll have achieved your target.

A session plan. This is probably the most important aspect of turboing. Without a plan you’re just mucking about and turning food and drink into sweat and noise. With a plan you’re turning your dreams into reality (providing you have a decent plan). The internet is full of great workouts and some rubbish ones too, so be careful who you listen to. Trainer Road (nothing to do with me) is getting increasingly popular as a source of training plans and individual workouts. I haven’t used it, but a lot of people think it’s great for motivation and there are several threads about it on the internet. Having a public record of what you’re doing is a good way to improve your determination to complete your plan.
 
A power test (optional). To properly determine your ideal workout load you should complete a power test to see what you're capable of. This is the pinnacle of suffering and any woman who says childbirth is painful hasn't completed a 20 minute power test. Basically, once you have warmed up you go as hard as you can for 20 minutes and then use the result as a guide for how hard you should be working for different workouts. If you average Xmph for 20 mins, you'd take 95% of this speed to give you an estimate of what you could achieve for 60 minutes (effectively your FTP), and scale workouts based on this figure. There are other ways of testing yourself and, using speed rather than power, there are lots of issues regarding repeatability, but if these are controlled you have a pretty effective cheap system. Add Trainer Road for a more expensive system, add a power meter for a really expensive system.

Determination. Once you have your plan you need to have the determination to complete it. However, just getting the turbo out and attaching the bike to it is usually the hardest part of any workout; that takes real determination. You know the feeling: your favourite soap is just about to start, you’ve had a very hard day at work sitting down in front of the computer, you deserve some ‘down time’, right? Wrong. You need some determination to get up, get nearly naked with a roll of clingfilm and give that turbo a seeing to. Think of it like this, your body is full of the physical energy as well as the mental ‘innergy’you need to turn your potential into success. Is that cheesy enough for you?

Bail-out plan. There will be times when you can't complete your chosen workout either because you're feeling weak or you've planned to do something beyond your capability. This is not a problem and everybody has bad days. Rather than just stopping and sulking, it's a good idea to have a bail-out plan so that you still get a decent session out of your time. For example, if I'm struggling I may decide to back my power off to a certain level until I recover, or let my HR come down to a certain level. Don't give up, give less, but make sure you give something.

Recovery. This is the period when your body turns your effort into fitness. If you plan to do 7 days of hard workouts a week you’ll end up doing 7 days of mediocre workouts and you’ll stop getting fitter. Bradley Wiggins has recovery days. You need recovery days. Some days you won’t be able to train due to other commitments; maybe you’re going to court or you’re confessing your sins on the Oprah show. If so, plan these days as recovery days and train around them.

Shorter Harder

Returning to work was a huge shock this morning, especially the getting up at 6am bit of it. The sitting at work bit was rubbish too.

Couldn't decide whether to do a workout or have a rest, but in the end I realised that I really should do one while I've got the chance because I don't know when work/home life may stop me. The longer version of Shorter Harder seemed to fit the bill, but the longer version with 5 extra intervals.


In the end I quite enjoyed it, with the 2011 Amstell Gold race on YouTube in the background the time seemed to go very quickly and by the end I'd almost forgotten about the sweaty pool on the floor and my 'gentleman's numbness'. After the last interval I ruined my cooldown by getting excited by the Amstell race finish and letting my power creep up and up.

It wasn't long ago that I found this workout difficult and now I can quite easily complete it even on the third day of a set. Despite the obvious fact that I need to increase the difficulty of my workouts, I just can't seem to get round to doing it. Maybe next time.....

Weekly Summary

I've had the luxury of a week off work to allow me to focus on getting some good training in and hopefully make some more progress towards my targets. I've even had the the opportunity to get out on the roads and do some normal cycling rather than the relative monotony of the turbo.

This week has been my biggest since the start of the experiment:

Time riding: 8 hrs 44 mins
Work done: 7700 kJ
Bikescore: 650

This is most obvious in the graph below showing time in power zones 3, 4 and 5. I've done more in each of these zones than in any previous week and at the end of it I still feel keen and strong; much better than I expected to. It will be interesting to see how going back to work will impact on my turbo workload.



I've also managed to reduce my weight to around 74.8 kgs (based on 3 days' measurements) so cutting alcohol and reducing chocolate seems to be doing some good. With the race season about 2 months away I'm not really that bothered about my weight yet, but I'd like to be a kilo lighter next month.

An easyish 50 minutes

I felt a little sore after yesterday's ride and run so I chose a simpler and easier workout today. I took ages to decide whether to do something easy or nothing at all, and in the end I went for the easy option because I knew I would hate myself if I did nothing.

After a warm up it was 4x10 at 272W, 288W, 272W then 288W with a short rest interval between them.

With an average power of 270W (86% FTP) it was a nice Zone 3-4 workout, but nothing too challenging and it was never going to hurt. I watched Stage 5 of the 2011 TdF as inspiration, the last 2 km of the race is just brilliant.

Road Hill Repeats

I woke up to a surprisingly mild Yorkshire day so I thought I'd make the most of it and get to a local hill for some intervals. I live about 8 miles from the lovely village of Crayke, which sits above the surrounding flat countryside like a beacon of pain. So my plan was to take a steady ride to the foot of Crayke mountain,completing smashing a Strava segment on the way there, and then do 6x5 minute hill repeats with a target power output of 330W (about 105% FTP), with roughly 4-5 minutes of downhill recovery between. I don't normally do this kind of specific training on the road, preferring to cover a variety of terrain over distance rather than turbo-style intervals.

The ride out went well and I felt good about smashing my previous time on the Strava segment by 36 seconds, getting it down from 6:10 to 5:36 and taking a King of the Mountain in the process. It also served as a good warm-up interval averaging 360W (115% FTP). It felt really good to be out on the bike and getting all the benefit of air-cooling and not having to suffer a stream of sweat dripping off my nose.

After a brief recovery I was into the 6 Crayke intervals. Below is a close-up of the 6th Crayke interval (the grey background shows altitude, red=HR, black = power, green=cadence and blue=current FTP).The altitude profile starts off quite undulating for the first mile or so, gently climbing 100 feet in the first mile and then ramping up another 150 feet in the last half mile. So, it's not exactly steep, but sticking in the big ring at the front means I have to get out of the saddle for the end of each interval. At the end, HR is in the low 170s which, for me, means I'm working quite hard.

The whole ride looks like this (without cadence and altitude)


The 6 Crayke intervals were: 5:21 at 337W, 5:19 at 350W, 5:14 at 341W, 5:11 at 333W, 5:14 at 342W and 5:15 at 344W. So there's not a lot of correlation between average power and time, which I'll have to look into.

On the way home after the intervals I thought I'd throw in another 330W interval on the flat, but 30 seconds in I thought again and backed-off until I got home. The Crakye intervals had done their job and my legs were quite tired which probably shows the limited road mileage I have done over the last couple of months. It's all very good having good 5-8 minute power, but not if you can't finish the 2 hour race!

Looking at the power profile for the ride it's very obvious that there is a big difference between road and turbo sessions. Rather than specific peaks for targeted zones, there's a flatter look and even some Zone 7 in there too. I find it hard to get quality Z6 and Z7 time on the turbo because I'm always seated.


After the ride I went out for a very gentle 5.7 mile run.

L'Etape de la Defonce simulated race

After yesterday's run and a long winter walk today I was keen to get back on the turbo before I started drinking to celebrate the end of a good year. This year I entered some good races, including L'etape de la Defonce in South Wales. After the race I analysed my power output and made it into a work-out that I can do to replicate the first 68 minutes of the race.



I last tried this workout on 14 Dec but as I was suffering with a hangover I struggled with some of the intervals. Today, however, I was full of energy and I completed the whole session with bags of power to spare. My heart rate was a lot lower (162bpm compared to 172) and I was always ready for the next big effort; I even managed a 5 minute 330W interval at the end (peaking at 370W). I just goes to show what impact the 8 pint hangover had when I last tried this workout. As a result I will raise the power levels for future sessions to make sure I am completely exhausted at the end.

I'll analyse the differences between the workout and the race later (link to follow), but I am quite surprised how closely the workout and actual race match.

Oh, Happy New Year.

30 minutes of fun

28 Dec. After a morning on the ski slopes of Xscape at Castleford, I didn't really feel up to doing much on the turbo but I guilted myself into it. By the time I finally got everything set up I was running a bit short of time so I planned a single 30 minute interval at 300W (roughly 95% FTP) while watching a repeat of the 4th Stage of the 2011 Tour De France. It's the one where Roy goes on a solo break and is slowly chased down (I won't ruin the end for you but it's a good stage).

I was doing well for the first 15 minutes, averaging a healthy 309W, but I though this would be difficult to maintain for the next 15 so I dropped it down to 300W. At 23 minutes I had a strange wobble where I felt like stopping, so I backed off for about a minute and then got back on the power and finished with an average of 304W (96% FTP) for the 30 minutes.
 
This is actully quite a good workout and the 23 minute wobble shows me that it is probably an area that I need to be working on and trying to extend my duration at higher power. So, more of this or 2x20 I think. It's just a shame they hurt so much!

The End of the World workout - Local Hero

Well, after hundreds of years of countdown I was getting ready for the Mayan prophecies to come true and for the World to end today. I thought that, if I was going to die, I may as well choose a hard workout to die to. Sufferfest's Local Hero seemed to fit the bill so I fired up the laptop, The Best of Thin Lizzie and set to work, expecting the World to end sometime during the 80 minute session. It didn't, so I had to complete the whole painful session.


During the second interval (around 25 minutes) I started to feel weak and I was starting to make excuses to give up, but I knuckled down knowing that this would be the last workout for 5 days so I really had to make it count. I didn't want to eat lots of mince pies over Christmas knowing I'd let myself down on a key workout. I did back off completely on the recovery intervals though to make sure I had enough in my legs for the work intervals and I really struggled to achieve the hardest part of the last 4 intervals; legs burning, sweat dripping, head drooping etc.

The Hunted - partial

I like the Sufferfest videos, so when I was struggling for motivation today I thought I'd do the first two thirds of The Hunted as it manages to hide some hard work within an interesting profile. I'm planning a hard session tomorrow so I decided before the start that I wouldn't do it all.

Everything was going well until the very last interval (2.5 mins at 340W) when I got the quits and backed off. I immediately felt like I'd let myself down and kicked in again to complete the interval. If I wasn't saving something for tomorrow I think I would have been able to complete the whole work-out.

Back in the game!

I've been under the weather for the last 2 days, generally feeling listless but not actually ill, no cold-like symptoms despite being close to people with colds. I haven't had a proper cold for 2 years and I seem to get run down rather than properly ill. After my average performance 2 days ago and a night on the sofa yesterday I wasn't expecting much from tonight's turbo session. I planned a longer version of Shorter Harder where I add repeat intervals (in reverse) at the end of the main set. This would allow me to stop if I needed to. But, I didn't need to......


Heart rate (red) was under control throughout, power (black) was always what I needed to do or more and I got to the end of the 90 minute session feeling quite good. Stats: 90 mins (32 in Zone 4) and approx 1250 kCals.

So again I am a little confused how my performance seems to vary so much from day-to-day, but it probably helps to explain why my race results can also be very variable. It's only when you see variable performance in a controlled environment that you can start to work out just how much performance varies.

Sufferfest: Local Hero

When I last did Local Hero it was after a rest period and I thought it was relatively easy, so I was interested in repeating it following 2 days on the turbo to see if it was still achievable. I felt fine for the first 30 minutes or so and then I started to get the quits after 50 minutes and I was trying to convince myself that stopping at 60 minutes would be fine and that I had done all that I needed to. In my head I was doing worse than the last attempt and I was happily making excuses to stop and hating myself for making them.

I then took the rest of the session an interval at a time and each interval minute-by-minute until I got to the end at 80 minutes. But, I got to the end and that's what really matters. The 400W peaks in the last 4 intervals really started to hurt but were short enough to endure the lactic fire and hang on for the recovery.


The stats are very similar to the last attempt and any variation is probably down to the recovery intervals rather than the work intervals.

Glossary

This is a description of the terms, abbreviations and concepts that I use in the blog. There are better guides on the internet, but this is how I understand them in the context of this blog.

FTP - functional threshold power. This is the maximum power I can output for a 60 minute period. As I have never done a 60 minute test I use a 20 minute maximal test and subtract 5% from the result. For example, I recently completed a 20 minute power test at 322W, so I can calculate an FTP at 322x0.95 = 307W. The highest 60 minute figure I have ever recorded is 291W but I still use the 307W figure for planning workouts.

Bikescore or Training Stress Score (TSS). This is a measurement used to estimate the training stress of a workout. If I did a 1 hour workout at FTP I would record a TSS of 100. 30 mins at FTP is 50, and so on. I don't like this figure very much as I find it very blunt and it hides a multitude of information. For example, a 60 minute FTP ride gets 100. A 3 hour ride at 175W gets 100. The 1 hour ride would kill me and the 3 hour ride would bore me.

Lactate Threshold Heart Rate (LTHR). The exercise intensity at which blood lactate starts to accumulate faster than it can be cleared. The highest average HR I have recorded in a race was 174BPM which is taken as my LTHR (based on training industry norms). Since I got a power meter I use HR less but I always have an eye on where my HR is compared to LTHR. In steady state I start to feel uncomfortable at around 162BPM and I'm hating life at 174BPM. My HR on a turbo is different to my HR on the road or racing so there is difficulty using a race LTHR as a real guide on the turbo. Also, as HR varies from day to day, LTHR is really only a guide.

Interval. Basically an interval is a period of exercise where power output is at a certain level. For example, I may do a pair of 20 minute intervals at FTP or 5x5minutes at 120% FTP. The theory is that doing hard work for short periods allows you to stress your body more effectively. I'm lazy and sometimes mix the term Session with Interval when I really mean Interval.

Traditionally these are written as the 'number of intervals' x 'duration of intervals (usually in minutes)', for example 2x20 or 3x15. There is, by definition, a rest interval (RI) between the work intervals but this is not usually stated.

KiloJoules (kJ). A measure of the work done during an interval, session, ride etc. The greater the number the more work has been completed. It is often used as a proxy for calories (kCals) burned during exercise as there is a conversion rate of roughly 1:1 between them.

Powerzones. There are 7 power zones based around a rider's FTP.


Zone 1 - Active Recovery - 0-55% FTP
Zone 2 - Endurance - 55-75% FTP
Zone 3 - Tempo - 75-90% FTP
Zone 4 - Threshold - 90-105% FTP
Zone 5 - VO2 Max - 105-120% FTP
Zone 6 - Anaerobic - 120-150% FTP
Zone 7 - Neuromuscular - 150% FTP+

Sweetspot. To confuse things, the sweetspot is further defined as 88-94% of FTP. This is generally considered to be the most efficient region to train in if you're looking to improve FTP.
 
The Quits. During hard workouts I often get a dose of the quits or the weakness. It's the point where I pathetically want to give up and do something else. Usually accompanied by whimpering.
