Think I did the the hardest workout of my build up to race season today. 3 sets of 7x80 seconds at 125%. 40 seconds rest between interval. 10 second ramp into each. ****ing hurt. I had to take some extended rest and back pedals. My legs were NOT cooperating. Riding at the same power after the intervals for cool down and my HR was 30 BPM higher than it was yesterday in a recovery ride. Was damn near throwing up a few times. But we got through it.
