2x20 at FTP

I didn't do my planned Chain Gang ride due to heavy Yorkshire fog so I did a 2x20 at FTP (306W) turbo session instead. I didn't know how I'd feel after yesterday's session so I was pleased when the first session went well and I achieved 307W. The second session started off OK but I had a bit of a wobble at 16 mins and my power dropped off and I started to have those thoughts about a hot shower and a nice cup of coffee. I was determined to complete the session as planned following my mid-week display of humiliating weakness and a short while later I found the reserves needed to complete the session on target, albeit with burning thighs and quite a lot of whimpering. Black line = power. Red line = HR.

Looking back this has been the most turbo time I have ever done in a week and I've tried to specifically target Zone 4 (276-322W) and Zone 5 (322-378W). I'm going to have a day off tomorrow so that I can do a harder session on Monday.
