Founders Brewing Company presents...
The Lumberjack 100 and the Michigan Ultra Single Speed Championship.
Michigan's only 100-mile mountain bike race! The Lumberjack 100 will once again utilize Michigan's beautiful Manistee National Forest, but with a new 33-mile loop snaking through the Big-M Ski Area for 2010. The Michigan style single track; composed mostly of hard pack trail, occasional sandy sections, and fast rolling terrain offers twists and turns that demand constant power, and total concentration as the trails quickly turn to nothing more than green blurs of forest. (If you're expecting easy, fire-road coasting, look elsewhere!) Ninety percent of the 33-mile, 3-lap race is comprised of this single track that will eventually push racers over 9,000 feet of total elevation gain.
From the pro/elite racers, to those that will find victory in just surviving a race like the Founders Lumberjack 100, the post-race meal/awards has also made this a must-be-there event for both racers and spectators alike. In addition to enjoying the catered meal; there will also be post-race prizes including a Cannondale Rush frameset, Velocity wheelset and other bike schwag awarded to random race participants.
The Founders Lumberjack 100 is proud to be a stop on the National Ultra-Endurance Mountain Bike 100 Series.
