4x8 steady state

Todys 8 minute efforts with 4 minutes between were 339, 350, 350 and 352. The first effort is always a warmup. I set the CycleOps to 340 watts. Effort two and three I went right to 350 from the start. The fourth effort I rode 2:30 at 340, 2:30 at 350 and then 3:00 at 360. HR was hitting 170 for the last few minutes of the last two or 93% of max or 106% of LT HR. Last years steady zone was about 10 watts lower but the last field test (2x8 minutes at 400) raised all of the zones.
