JOIN US JUNE 17, 2017

Michigan’s original 100-mile mountain bike race! The Lumberjack 100 always takes place on the third Saturday in June (June 17, 2017).  Registration will open on Bike Reg January 8th, 2017 at noon eastern. The Lumberjack 100 will once again utilize a 33-mile loop through Michigan’s beautiful Manistee National Forest and the Big-M Ski Area. The Michigan style single track is composed mostly of hard pack trail, occasional sandy sections, and fast rolling terrain offering 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, Founders Ale and awards has also make this a must-be-there event!
