There's running, and then there's running.

Sunday's US Half Marathon happens to fall into the latter category, which means it's time to ditch the ratty tee you've worn to the gym since college and invest in some serious running gear.

Even though you'll probably look a bit, um, flushed by the end of the race, this week's look guarantees you'll still look fab when crossing the finish line.
