The Horribly Hilly Hundreds lives up to its name as the Midwest’s most notorious cycling sufferfest. This Wisconsin classic draws over 1,300 riders annually who come to tackle what many consider one of the hardest single-day cycling challenges in the region. Demand has grown so intense that entry now requires a lottery system.

Three distance options test different levels of masochism. The full 200K covers 124 miles with a punishing 10,700 feet of elevation gain across 40 significant climbs, including a brutal 910-foot final ascent. The 150K delivers 9,300 feet of climbing, while even the “short” 100K option packs 5,700 feet of elevation into 66 miles. Organizers recommend a minimum 27-tooth rear cassette and suggest bringing extra tubes and spare parts.

The course winds through Wisconsin’s scenic byways around Blue Mound State Park, with the terrain featuring everything from rolling 50-foot bumps to sustained climbs that will have you questioning your life choices. Full-service rest stops provide crucial refueling opportunities, supported by sag wagons, medical assistance, and repair trucks positioned strategically throughout.

What sets this event apart is its reputation among seasoned cyclists as a genuine test of mental and physical fortitude. The community atmosphere balances the suffering—riders bond over shared misery and celebrate together at the finish. The event also serves as a fundraiser for Blue Mound State Park improvements, giving your pain a greater purpose.
