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.
