For what might be described as true dedication, it'd be hard to beat Tremendi, who blogs at Diary of a Cold Water Novice. Here's how he describes himself:
I'm just a normal guy experimenting with some new ideas. Trying to get physically fit, in shape and toughen up using some unorthodox methods, such as cold water immersion and pain control. I also like to run shirtless in "any weather, any temperature" as part of my normal routine. My blog describes some of those activities. Why not take a look at my blog and make a comment or two. Maybe it will inspire you to run shirtless too.
Here's a taste of Tremendi's discipline, in his own words:
"I haven't yet hit a low temperature that I wont run in. The distance that I will run may vary depending on the temperature but I don't think I have hit an absolute minimum yet. It has been quite cold in the UK this winter but I have continued to run shirtless (i.e. in just shorts and trainers) all of the time.

I will do my normal 7km (4+ miles) circular route from home shirtless in just about any weather and temperature (a few Mondays ago it was -2C windy and snowing so probably with wind chill around -5C or -6C conditions) and another weekend I ran 10km shirtless in -4C with clear and windless conditions for an hour with a group of 3 other guys (who were all dressed for a Siberian winter!). The coldest I have run shirtless in was just over 4km @ -6C with a fairly strong
wind chill.
If it was really cold (like below -10C) I would probably do shorter (500m to 1km) "out and back" runs so that I could quickly escape the cold if I got to a point where I was really feeling the effects of hypothermia.
In the USA, I think a great place to run in such cold conditions would be around the perimeter of a large shopping mall. Then if you got really cold you could duck into the shopping mall to warm up or cut back through to where you parked your car!
The more difficult question in my view is what is the highest temperature you would run in - that to my mind is a far more dangerous situation for a runner.
I haven't entered any races yet and here in the UK I think that for an actual race (unless its a fun run) you are required under the UK Athletics rules to wear a vest or shirt to display your race number - so that really sucks!. It would certainly be one question I would ask of the race organiser - "Can I run shirtless?" - before I entered the race."
