Lowest temperature worthy of a shirtless run?

Exactly. I go shirtless when its above 55.

Think I've done it in the 50s and rain to avoid nipple chafe. But probably at least 60s for a humid day, and 70s for a dry, sunny day. All in degrees F for our international friends.

If you're running through the Arboretum, you can go to about 50F. If you're running around Library Mall/Memorial Union area, go 45F to show off to the hotties. If you're in your parent's basement on the treadmill, about 60F. If you're running past the deadbeats begging for change in front of Noodles & Company on State Street, 85F.

45 is about the lowest I'll go.

58° was the first temp that came to mind on a training run but I have run a roadrace shirtless in the high 40°'s when it was raining.

I never go shirtless!

I ran shirtless the other day in 45F and sunny. My morning runs have been about 10F, so 45F feels like summer.

That's what I'm saying. It's all relative...50F right now feels much warmer than it will in 4 or 5 months.

Depends on if there is sun or wind.

But, in college me and my friend had a basic rule of shirts off when it's over 40.

Just as a general observation, I've noticed that people up north in general tend to wear more clothes to run, no matter the temperature. So if it's 45 degrees out a runner down south might be shirtless while one up north would have at least a short sleeve and maybe a long sleeve shirt on.

you must have it backwards, people down south (even in mid states) wear so much more colthing at lower temps thatn northerners wear.

Definately seems backwards...

I know people in the south (from both coasts) who will rock sweaters below 60...

After your session in Club 5, you might be so steamy so as to not need a shirt - even at sub 30F.

never would have done this before coming to this locale, but i rocked it shirtless (with gloves) today for a 43 degree hour run

The hands are always the first to go.

I mean during runs...

RUnners down south.

Walking around is different, but on runs, runners from the south wear less clothes on runs then runners from up north.

Having lived in both places, that's just my general observation on watching people I've run with.

I'm most comfortable being shirtless until it drops under 50. If it's raining, then I'm going shirtless unless it's below 40. I hate wet shirts.

When I spent a semester in Wales in college most afternoons it was high 40s/low 50s, moderately windy, and damp I'd usually go shirtless

you do know that north is well... 'above' the south on the map, right?

Man, I wear a shirt up until 80F. Anything cooler than that and I will need at least a T-shirt. Anything under 70F and (if I even make it outside) I have to have pants, long sleeves, gloves and a hat. But most of the time at that point I'm inside on the treadmill.
