Good stuff. Especially this:
I would recommend beginning a pre-acclimatization process at least one month before competing in this type of environment.
I always thought of doing this for the final 2-3 weeks before an important event because I've always heard it takes about 2 weeks to acclimate but there probably isn't reason not to begin a month or more out. Pretty timely advice for me at about 6 weeks out from a warm weather marathon. I was going to begin overdressing at about 2 weeks out but maybe I'll begin pretty soon.
