The Birchwood 100 Mountain Bike Race stakes its claim as one of Wisconsin's most demanding and exhilarating endurance rides. Stretching over a grueling 100 miles of mixed terrain, this race beckons riders into the thick of northwest Wisconsin’s wild forests, rolling hills, and stinging trail sections where every pedal stroke counts. From the quiet rise of dawn to the long shadow of dusk, the race course pushes riders to engage with nature that asserts itself as fiercely as the competition itself.

Starting near the small town of Birchwood, riders taste the raw challenge immediately: elevation gains that test your legs and lungs, mixed with trails that shift between firm dirt, roots daring your tires to hold fast, and rocky segments that demand total focus. The forests here do not gently whisper encouragement; instead, they lean in, branches and roots alike ready to challenge even the most experienced riders.

The course rolls through private and state lands, featuring continuous undulating terrain with roughly 6,500 feet of cumulative elevation gain. This race is not just a test of speed but a study in stamina and steady navigation—particularly important since trail markings, while clear, require constant attention if you want to stay on route without losing momentum.

Hydration and nutrition strategy can make or break your ride on this course. Pit stops are limited and spaced out, so riders must carry sufficient water or plan for refill points carefully. Tough rubber tires with puncture resistance are highly recommended due to mixed rocky and root-laden surfaces. Footwear with excellent grip on pedals increases control over rough sections where balance becomes a silent partner in your journey.

Timing your race starts is also crucial: early morning starts offer cooler temperatures but limited light if delays happen, while midday risks heat that challenges hydration. The race usually unfolds in mid-September, striking a balance between the end of summer’s warmth and the crisp approach of fall—expect changing temperatures and rapidly shifting light.

To succeed here, respect the land as it commands you to work for every mile. The Birchwood 100 is an engagement with terrain that does not yield easily. It’s a ride that rewards preparation, mental grit, and an awareness of every twist and turn that the Wisconsin wilderness throws your way.

For those thinking beyond competition, the trails offer vivid colors as fall deepens, with bursts of reds and golds shading the path. Still, the forest remains a careful adversary, requiring respect and readiness every mile. Beyond the race itself, exploring Birchwood and its surroundings offers a grounding counterpoint, with friendly locals, rustic accommodations, and quiet moments to reflect on the ride just completed.
