during my VO2max intervals today i came to some downhills at maybe 4% and with a headwind. i had to go 100% effort just to keep my watts near my targeted zone. as soon as the road leveled off, my preceived exertion was much lower with power in the same zone. then i hit a moderate upgrade and it's a piece of cake to hold the power in target zone. my cadence was relatively the same, slightly lower on the climbs.
anybody want to explain this?
