At the end of the day us runners are an odd bunch.
Check out any given race, and you'll find of women of all shapes and sizes will cram themselves into the tighest lycra they can find, and reveal monstrous massive camel toes and jiggly flesh.
You also get the men who think that taking that extra slight bit of material off their shorts will make them 0.02 seconds per mile over a half marathon, resulting in near indecent exposure.
Would never wear tights....and have raced cross country in some very cold weather. But then again once you're at race pace it suddenly feels pretty warm. Track suit bottoms perhaps for ultra cold weather..ie snow, when it's a training run and you're not going to reach paces to keep you warm.
