2x20 at FTP

With only an hour or so before I had to do some chores I planned to do another 2x20 at FTP. The first session went well with a nice steady power output and a gently rising heart rate and beating the 307W target by 2W. The second session started well but quickly got ugly. After 12 minutes I started to have doubts I would be able to complete it with a highish HR and a lot of sweat dripping off my nose. It was then that the 'bouncing' started; periods of feeling OK interspersed with periods of feeling terrible but never feeling good. I've highlighted the suffering portion in the graph below:

Black = Power. Red = HR.

Normally I'd have stopped at this point, had a shower and put it behind me but I was determined to finish the session on target. With 3 minutes to go I started a hard push which lasted about 30 seconds before I had to back off and then with 2 minutes I started to ramp up to increase my average power from 304W to my target of 307W, rocking from side-to-side. I managed to finish with an average of 306W. So close but not quite there!

After a short recovery I was able to do some messing around to get my total calories up to 1000 and finished with a Bikescore (TSS) of 88.

Sufferfest: The Hunted

Feeling a little sore (a strange glute soreness I've never had before) and a poor night's sleep, I was expecting to suffer when I started Sufferfest's The Hunted. With BBC iPlayer fired-up and me sitting almost naked in a kitchen with all the windows and doors open, I clicked the start button. Things started off well enough, particularly as it takes 30 minutes before you get anywhere near a sustained FTP+ effort, but when it does it's a variable 9.5 minute feast of effort above and below FTP which raised my HR to my Lactate Threshold. After a short rest itI settled into the fairly relaxed 80% FTP session which allowed my HR to drop before the final 5 minutes of increasingly challenging intervals at around 115% FTP. With a couple of minutes to go I got the usual feelings of just giving up but I was determined to finish it and just grimaced and whimpered my sweaty way to the end.

Bikescore (TSS): 78. Black line = power. Red line = HR.

Afterwards I'm feeling quite smug that I've managed to complete 2 Sufferfests in 2 days. I'll probably have a day off tomorrow before beasting myself again on Thursday. 'You have to have easy days to make sure you can do the hard days' as a wise coach once said.

Sufferfest: Local Hero

After a day off the turbo yesterday and having a day off work today I was hoping for a couple of hours out on the roads to do some road sessions. Unfortunately the 2 days of continual rain has flooded all the local roads so I was doomed to another turbo session. I've had the Sufferfest Local Hero workout on Golden Cheetah for a while but I have never liked the idea of a 90 minute turbo session; today I thought I'd finally give it a go. Without the video I though it could get a bit monotonous so I ran old race videos at the same time to keep me entertained (more on that in a later post).

Here's the plot for today (complete with HR monitor faff at the start). Black line = power. Red line = HR.

Ignoring the warm-up and cooldown the session lasted 75 minutes with an average power of 263W (xPower 274) based on an FTP of 307W. At the end of the session I felt like I had some more left in my legs so I threw in a couple of extra  intervals taking the whole session up to 90 minutes with a total Bikescore (TSS) of 115. Looking at the trace you can see that the intervals just touch the top of power Zone 4 (light blue, 30 mins) and just into Zone 5 (green, 10.5 mins). My HR also looks like it was under control reaching  maximum of 168 so I was never bouncing off my Lactate Threshold and thinking about stopping or even that I was suffering too much.

So overall a good session and I felt a lot better than I expected to. Doing this workout again will probably let me know if the workout needs to be done harder or whether I was just well-rested for today.

Set-up

Mid-session data view.

I use Golden Cheetah v3 when I'm doing my workouts giving a live readout of key parameters. It's completely customisable and is great for post-session analysis too. Here's a screenprint taken at the end of today's session, showing the HR, power, cadence and speed traces in the main graph, short-term power and HR in the smaller graph, as well as target power, instantaneous power, cadence, HR and elapsed time in the smaller windows. The data is gathered from a Garmin HR strap (£32) and a Powertap G2 Pro+ hub (£loads). This data is recorded on the Garmin 800 (£250 ish) as well as straight onto my laptop via a Garmin ANT+ dongle (£25).

Success!

After a disappointing session yesterday I thought I'd repeat it with exactly the same set up.

Black line = power. Red line = HR.

 

As you can see, I managed to compete it and quite easily too. My heart rate was significantly lower than yesterday, with a peak HR of 167 compared to 175 which I think has something to do with my lower cadence (around 14 rpm lower than yesterday). I even managed a 480W blast at the end, just for fun.

 

So what have I learned? From day to day my performance varies a lot for no apparent reason. I just wish I knew why.

 



2x20 at FTP+

Tonight's Turbo Trainer session was a 2 x 20 min at FTP (target 306W) with 10 mins warm-up and 10 mins between the intervals. I felt OK for the first one (average 307W achieved) and had enough on the second to surge at the end (average 313W achieved). Again, it was a horrible hard and sweaty session and one I was pleased to get off the turbo at the end of. The 66 minutes went very quickly though.

Here's the trace showing a poor start to the first session (bike faff) and then a lot of power to try to get back to a 306W average. As I was above target towards the end of the first session I backed-off. The second session shows a big increase in power output from around 17 minutes. Black line = power. Red line = HR.

Start the experiment...

I have decided to record my attempts to improve my power over the next 5-ish months. While I have taken cycling and training semi-seriously over the last year I don't seem to have improved much so I think I need to be a bit more methodical about it.

After 5 weeks off the bike I went on a training ride yesterday and was very disappointed at my performance on the White Horse Climb (aka Low Town Bank climb on Strava) , which I usually love. For some reason I was struggling up in the granny gear and on each of my 3 climbs I got slower and felt weaker. At the top on the last climb I could barely breathe and my throat felt very constricted so I'm hoping it's not fatal.

Anyway, here's a section of the power and HR trace from the 3 climbs. Black line = power. Red line = HR.

When I got home I analysed the data (on the fantastic Golden Cheetah 3 software) and noticed that on each attempt my power was lower than the last and my HR was lower too, even though I felt like I was trying as hard on each climb. While my best time on the climb is 7mins 10 secs, my fastest on this day was a terrible 8:57 and my slowest an embarrassing 10:04!

So, time to do things properly and train with a method and a plan. While I've had the excellent Training and Racing with a Power Meter for a while, I haven't taken it too seriously, but now I think it's time to as well as inputs from other sources to develop a plan aimed at improving my power.

The first step was to complete a 20 minute power test. Having done several before I knew the importance of pacing myself and not going too hard too soon. I was hoping I could achieve 320W for the 20 mins so I started off just below this and let my power build through the test. With 1 minute to go I dug hard to use every last ounce of energy but quickly went into deficit and had to back off, then managed to surge for the last 30 seconds to achieve 322W. Incidentally, this is exactly the same result as a 20 min test I completed last November so I hadn't lost anything, which is good. By the end of the test I had given it my all, I was unable to speak and just slumped over the bike. I don't like doing these all-out tests because they are painful and relentless and on the very limit of what your body can achieve (at least they should be to be an accurate test).

So here's the power and HR trace from today's 20 min power test. Black line = power. Red line = HR.

Note how the power trace is quite smooth for the first 12 minutes or so, then starts to wobble a lot, before going manic for the last 2 minutes. In the last 2 minutes I go from feeling exhausted to OK and back again as my body loses then finds new reserves of energy.
