Back to the hot weather. It was 90° after my aerobics class when I went to the fitness trail to run intervals, 9 x 1 min, with an abbreviated warmup since I'd come straight from the gym.

I actually had to back off the pace of the last two because I felt like I was starting to overheat. When I look at the track my HR wasn't outrageously high - topping out at 181, about normal for intervals - but I was starting to feel just slightly dizzy, so it was probably the better part of valor to take the last two not quite all-out. (Even though the trail is right next to the hospital. )

Then back to the gym for my shower, and after that it felt just FREEZING in there.
