On Sunday, Park City ultra endurance athlete Matt Garretson will begin the Iditarod Trail Invitational, a 1,000-mile human-powered race from Anchorage to Nome. A bike-packer for eight years, Garretson has sought to complete the Great Divide, Baja Divide, and Iditarod races. Last year the weather-dependent Iditarod race took 18 days. On a fat tire bike with studs, Garretson hopes to raise $50,000 for Alaskan villages affected by a typhoon.
