What's amazing about the Bolder Boulder with 50,000+ runners is that you can see three different races on the same day. With my GoPro, I captured all three of them:
* "Personal best" run: My day's first 10k run in the AA wave.
* Fun run: My day's second 10k run, for fun, in a later wave with Amy and Tori (the blue and yellow Power Rangers.)
* Elite race: The elite runners finishing in front of 40,000+ spectators in the Colorado Buffaloes football stadium.
