It thought we were finally going to see some 100°F temps here, but turns out it was just the "real feel" number that drives me nuts. However the dew point has been very high and all day, not just mornings, so it's been sweltering.

My afternoon rides have seen just 95°F temps. It's hot when slow, but as long as I can maintain 14 mph and am sweating, I seem to be cooling sufficiently. Speed up over 16 mph and I can't even tell it's hot. Slow down to 10 mph and I know it's hot.

Last Saturday I went for a 30 mile ride right about noon. Same temps but dew point was higher still. Sweltering! Still pretty much just the issue of losing cooling when slow. I did note that since it was about noon and the sun pretty much directly over head that there wasn't as much shade as there is later or earlier in the day. Also, I could feel the sun bearing down on my black cycling shorts but not near as much on my light colored jersey.

Might be nice to find some shorts or bibs with white or light colored outer panels, but dark inner panels for embarrassment protection of sweat stains, seat stains and other stains that look like urine stains! <grin>

Another thing I did was rest about an hour then go walking 4 miles with my wife. We both were miserable in the heat and I could tell I was much hotter than when riding that day. And most of the walk was shade. When getting home, I checked my body temperature and it was 99.6°F. I thought to check my temperature immediately after a 22 mile ride mid-afternoon yesterday and it was only 98.6°F - normal.

I think I'll try to check my body temp more often after rides, walks and other activities. I'm wondering how well it will correlate with my position that being able to maintain airflow around ones body is a big factor for cooling, Even when that airflow is created by hard effort to maintain speed.
