Why is it sooo hard to keep watts up on downhills?

    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?

    Yes indeed. This is the case for the majority of us. The neurological demands of generating power at speed/higher wind resistance is just way different. It's why in a race situation, you're better off trying to get aero at high speeds vs. trying to turn out the watts (assuming you don't run out of gears). But in any event, I definitely try to avoid descents when doing intervals! :)
