"It's not engineering, it's physiology. 200w all the time is faster for less physiological demand than 300 uphill and nothing downhill. (Figures plucked from arris but for concept)."
"The idea of pushing more watts to go up a hill is a false notion anyway - those extra watts gain you height, which is regained in speed coming back down (unless you reach terminal velocity, which depending on your bike handling may or may not be terminal!). The only time you waste that energy is when you brake.
If you want to expend your energy where there is less aerodynamic cost... save it for the run"
Sigh, help, I feel a bit stupid here. I really don't understand this. Are you saying it is good to pedal downhil or not? I read the first of those quotes as saying extra effort uphill/none downhill is bad and the second as saying it's good, I know I'm misreading it but I've got to the point where the more I look the more confused I get
