My range is usually 10-90. The lower and upper ranges also vary depending on windchill/ humidity. Overall, It’s just downright unpleasant on the other side of both of those temps. You also need the proper gear on both ends of the spectrum.

I won’t run on ice or if it’s super windy. We lived in MI for a decade and it gets very cold there. As long as the path wasn’t hazardous I’d be out there, barring frostbite advisories (frostbite risk with 5 minute exposure).

I’m far more sensitive to heat, so depending on humidity and the heat index, I usually cut off around 75 degrees, which means early morning or late evening runs. I’ll pass out if I get overheated, and fainting on the trail isn’t an ideal situation, so avoiding heat is a must.

min 20 (if it's not icy) max 85-90 depending on humidity

Maybe 10 is my minimum? But really it's about whether ice is on the street/trails.

My max is about 80-85.

My min is 10 air temp. With wind chill, I can go to 0 or a few degrees below.

Max is 90.

55 min
75 max

40 is my limit unless it's a race day or I NEED to do it because I'm training for something.

Guess I'm a wimp. I hate breathing in sub-30 degree air when I'm running. Last time I tried that, I spent the rest of the morning coughing my lungs up. Now I head for the gym when it's much below freezing.

I've learned that 25 (but no wind) is actually my ideal preferred running temperature. I don't have a "low" - I ran all through all the cold weather spells we've had this year. I am definitely a cold/winter weather runner.

Summer is awful here. I hate it. I might sneak in MAX 20-30 minutes, when it's hopefully not too sunny, humid, or with at least a breeze. I often quit running in the summer, period. I can't breathe in the thick air, so turn to cross training.

I don't run for my own fitness, I run for the dog, who loves the cold. So it's every day, with no minimum temp. I won't run on ice, though, for my own safety. The dog just skates happily along and crashes into things, but no thanks for me...

There's no magic temperature for me.

A lot depends on humidity and wind and clouds. I've gone running on days where 40 degrees/cloudy feels colder than 28 degrees/sunny.

Just out of curiosity, what’s the minimum temp that you’ll run outside and the maximum temp? For me I will not run outside unless it’s above 32 or below 80.
