If you are a fan of cross country biking or triathlon, then chances are you have heard of Linsey Corbin. After graduating from the University of Montana, Linsey has gone to become one of the titans of the sport of biking and triathlon. Simply put, Linsey is a certified badass. The next BIG Ironman race is coming up soon in Brazil, and Linsey gives us a insider look on how she prepares for one of the most grueling races on the planet.

What is in store for Linsey? How about a 2.4-mile swim, a 112-mile bicycle ride and a marathon 26.22-mile run?

According to Linsey's husband, also a UM grad:

Linsey asked me to provide SAG for her 7 hour day, so I suction cupped a camera to the truck and took 5,000 photos. Many were throw aways but here's a couple thousand.

The result is a really cool video, showing what it takes to prepare for a BIG race.
