On a frigid day at Hatcher Pass, north of Anchorage, Alaska, cross-country skier Holly Brooks glides up to a start line.

This race is just a practice with her Alaska Pacific University teammates. It's a chance for Brooks to test her skills before heading to Europe for the busy World Cup season, and then to Sochi in February for the Winter Olympics. Brooks is now a seasoned member of the U.S. Ski Team, but a little more than four years ago, she was on the sidelines.

On July 4, 2009, that all changed.
