Early this summer I will be riding a century in south Texas with expected hi's in upper 90's. Five years ago I did the same ride and bike computer recorded over 100 at the end of the ride. No chance to ride in similar temp's before the ride. Any ideas on how I might simulate/acclimate myself to riding in hot weather? Have done quite a few centuries so I understand hydration, nutrition etc. I will not have a problem with the 100 miles. As an 80 year old I just want to have a safe ride.
