But, most of us run/bike more slowly on hot, humid days when we're going any sort of distance. It must help if you're running a 100m sprint to have hot, humid days, but it doesn't help my 10k run or 40k bike times.True. But on the other hand, I often race track (cycling) at the LA velodrome. And despite having pristine pine boards, is a slow-ass track. I chalk it up to its overly refrigerated and dry air (I get a cough every time I spend a day there). And of course being at sea level. It's 3/3 for the things that increase air density.
