Triple D Winter Endurance Race: Twenty Years of Cold Questionable Ideas

The circus is still in town.
In 2007, a handful of ruffians pointed their bikes into a Dubuque County winter and called it a race. The early years (2007-2012) were louder, less legal, and considerably more dangerous. Twenty years later, the circus has a permit, a few more rules, and the same questionable sense of humor about frostbite.

The route: Dubuque. Durango. Dyersville. Three D's, one long thread of trail. Ride it, run it, or skate it. Riders have long favored the 52-mile round trip between Heritage Pond and the Dyersville trailhead, remote and scenic, with very little support. Bring what you need, and bring a sense of humor for the rest.

The acts: Juggle water bottles down the Heritage Trail. Tightrope a bridge barely wider than your tire. Walk it, pedal it, or skate it. Every ability is welcome under this particular big top. The only requirement is that you show up willing to be a little ridiculous in the cold.

The ringmasters: The Triple D is organized by the Tri-State Mountain Bike Riders (TMBR) of Dubuque, Iowa, and run entirely by their volunteers. Yes, your entry fees deliver piping hot food and beverages and endless frost - while the remains go straight to the club and its mission to make the Tri-state a destination for mountain biking and outdoor recreation, by building, growing, and sustaining the trails closer to home.
Twenty winters. Come write the next legendary story.
