i've never heard that. in fact, i've heard the opposite. bc you sweat more. That's why some ppl wear heavy sweats when they work out.

I don't know if you burn more, but I do know from experience that being cold makes you run a lot faster.

Hahaha, so true

I read an article about it once, don't really remember. I do know that running when it's cold makes it more difficult to breath because you're breathing in all that cold air at a really fast rate. (ie; during winter) I used to run a lot during the winter and I'd end up feeling sick. Makes sense...

either way - here's an article. No you don't burn more because you should be properly dressed:

ps. runnersworld.com has answers for everything

no, being cold doesn't make much difference. the body likes to hang on to fat when it's cold anyway so i wouldn't say being cold is ever a plus when it comes to weight loss.
