Lunch- 8. I wasn't suffering quite as much as yesterday but it was still pretty ugly. I'm really sluggish. Didn't make the whole 10 miles I wanted.
Pm 40 min in a 190 deg sauna, plus 5 min in a steam room. Hot. Sweaty. Websites say to heat acclimate by starting at 15 min and build up to 45-60 min, so the fact I could stay a long time right at the start was encouraging. Of course, they also say to not start heat acclimating until 2-3 weeks pre race.
