This weekend marks the unofficial start of summer here in the U.S., and already where I live we’ve started experiencing some summer-like heat and humidity (along with some very summer-like thunderstorms ⛈️).
I’ve started thinking ahead about summer already as I’ve been hearing — and probably you too — about the powerful El Niño that’s brewing right now in the Pacific Ocean, which could lead to some big changes in the weather we experience this summer.
And that made me wonder: what’s your threshold for running outside in the summer heat, what’s your red line between “sure, I love the heat!” and “this is too much, I’ll stay inside or run on my treadmill”?
How warm is too warm for you to run outside, and what is the hottest you’ve ever found yourself actually going outside to run? — Terrell



I've become such a wimp about running in hot weather. I used to be able to handle high 80s, even low 90s. Now I really don't want to run at all when it's in the 80s. That's when everything becomes painful (literally I get blisters).
Living in Texas, if I wasn’t willing to run in 80°, 90°, even 100° heat, I would not be able to run in the summer. I just grin and bear it, so to speak. Not a fan, and boy do I sweat a lot… I used to get up early to run before the heat set in (though the humidity is much worse early, before it has burned off). Now because of sleep issues, I just can’t get up that early anymore. So I try to run midday. In summers here, the hottest part of the day is 3-5pm. So if I run at lunchtime, it’s still hot, but I’m avoiding the worst of it.
