Horribly Hilly Hundreds
June 14, 2025
Since 2003, Horribly Hilly participants have enjoyed a day of riding that results in an awe-inspiring accumulation of 10,000 feet of elevation gain in the Driftless Area of Wisconsin. Choose between the 100K, 150K, and 200K routes. The day is capped with a meal featuring quality local food and beer.
