Hey 7 - Here's your premium:

I have a bunch of these shirts that I wore when I ran and I LOVE them. Even though I no longer run, I still wear them (because they look nice) and I get lots of compliments from people. Wore one last week to the LBS and everyone thought it was cool.

I think runners get tired of the same old t-shirt that they get at races so it's nice to have the option of getting something different. The Annapolis 10-miler is famous for having a different "premium" every year and the runners love the idea.
