With this crazy heat wave going on, I've been day dreaming of cooler weather. I prefer temperatures around 20 degrees (68F).... Give or take a few degrees. Temps in the 30's are just brutal. If you take the humidex into account, we've had temperatures in the 40's the past couple of weeks.
As much as being injured sucks.... I'm really glad that I don't have to do long runs in this furnace!
