    1. saw a thing about Alex Dowsett's "how far can you cycle in an hour" thing tomorrow, which he's doing at a velodrome at altitude in Mexico... i asked a friend about the altitude part, and she linked me to this wild page wolfgang-menn.de/altitude.htm

    as you get higher up, there's less air to push through, which makes you faster. but also there's less oxygen to breathe, which makes you slower. but you can plot those two factors against each other, find the intersection and thus identify La Paz in Bolivia as correct at 3400m.

      the way cycling breaks down human exertion into quantifiable numbers is so fascinating. but the flip side is that those numbers assume arbitrary amounts of suffering on behalf of the cyclists.
