heat, with the caveat that I live in San Jose CA to it does not get cold
note: cold to me is below 0 F. I grew up in montana and 40 below 0 (same F and C)
I can dress for cold but when it get's hot I slow down to avoid issues with heat.
I can see on my HRM that when it gets hot my HR goes up if I keep same speed on a route, so when is is super hot I slow down and don't let my HR get above the lower thresh hold that I ride to
