I ran for a small D1 school and used to run with shorts over tights until I was back home visiting and ran with some of my friends at the large D1 school where I grew up and I was told it was a 'no no' to run with shorts over tights so I stopped then and haven't since.

Edit: I do however run with tri-shorts or Underarmor boxer briefs under for a little extra warmth and so the world doesn't have to see my mushroom outline.
