I live in the northeast, temps here have dropped quickly this year and our highs are consistently 60s now with many days being 50s.
I am training for st George in 4 weeks abd don't want to loose all of my heat adaptation.
I don't have anywhere to train indoors that is climate controlled, basement and garage are the only options.
What is the best strategy to employ these last 4 weeks to keep me comfortable and somewhat adapted to heat?
As others have mentioned, heat probably won't be an issue. That being said, I can offer some advice. I faced something similar when I trained for IMTX, which is in April, while living in Chicago. My warmest
outdoor ride before the race had a starting temp of 32 and on the day of IMTX it was in the upper 80s.
I did heat acclimation training 2-3 times a week for the last 3-4 weeks before the race. I would run indoors in winter gear and then immediately take a very hot, long shower; about as hot as I could handle. A couple times I overdid it on the shower and got nauseous. I'd usually sweat profusely for 10-15 minutes after getting out of the shower.
I'd also did some of the my rides on the trainer with the temperature a little warmer than usual. I didn't do anything crazy on the rides-- I kept the fan on. Also, I did not turn up the temperature for long rides. The heat acclimation was mostly stuff from 90 minutes down. I figure that, unless you have a lot of fans running and windows open, you are always dealing with heat on the trainer so there was no need to overdo it there.
I was also able to get one run and one ride in while I was in TX in the days before the race.
All in all, it seemed to work well. I was definitely hot, but I didn't struggle with the heat any more than I expected.
