Shawn is attempting to become the first woman to complete the nearly 1000 mile Iditarod Trail Invitational (ITI) solo. Running over 100 miles per day with her husband Tony by her side, she endures harsh conditions, navigating whiteout storms and narrowly avoids falling into a hidden tree well. After Tony leaves in McGrath, she continues alone, passing other dropped out racers. Slowing her pace but determined, she pushes on through the remote Alaskan wilderness towards her goal in Nome.
