Guess this is what a self-inflicted beat-down looks like, charted over an hour forty five.
Buckets of sweat later!
The 45 minute warm-up was too long at 50% FTP. Not enough left in the tank, intensity wise, to hammer the second interval. It was all sufferfest from there.
On the flip side, trainerroad.com finally got their custom session builder deployed. Very nice.
