Michigan’s original 100-mile mountain bike race is celebrating 20 years in 2025!
The Lumberjack 100 always takes place on the third Saturday in June (June 21, 2025). 

*PERMITTED BY THE U.S. FOREST DEPARTMENT

The Lumberjack 100 will utilize a special 4-lap route for the 20th anniversary in 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!) For the 2025 event riders can expect an approximately 25 mile lap with 90+ percent singletrack. Total elevation gain will be a bit higher than the standard 3-lap course in the 9-10k feet of gain range. You’re not going to want to miss out on this unique 20th edition. From the pro/elite racers, to those that will find victory in just surviving a race like the Lumberjack 100, the post-race meal, Blackrocks Brewery refreshments and awards also make this a must-be-there event!
