the heat of Los Angeles

pretty brutal, poor dude.
link.

Yeah that’s about 40 deg c,
I read an interesting article on training and racing in heat in a ride mag a few issues ago.
It was about a rider who was pulling long turns and maxing out in a hot race and suffered a stroke because of it.
The specialists in the article were saying anything above 36 is danger zone.
The risk of serious injury incl strokes was greatly increased.

Vets cancels if it’s 35 degrees or more.
