Seriously, no running at 80 degrees or above. It was 82 at 20:00 and the
sun was going down, so I didn't really have any choice. My legs felt
fine, but I just couldn't stay cool. My shirt was completely soaked. My
skin was wet before I even started sweating.
I think this would have been a fast run, but I was just overheating by
the halfway point. Still, it's the fastest 25 minutes I've done yet.
tl; dr - Waaah it's hot.
