I’ve learned from experience that sleep is crucially important to cycling. Even for recreational cyclists like me. Even if I’m in bed, but awake, I’m just not running at full steam the next day. There are the obvious things, like it’s much harder to pull myself out of bed, and I have less motivation, but it’s more subtle, too; my legs haven’t recovered as much from yesterday’s riding. I’ve learned this is true enough (eg it wasn’t just that one time) that I actually plan my social life around it. But I’ve never really known *why* it’s true. Thanks for cluing me in!
