Rumble on the Ridge
Did somebody say more Cowbell?? Rumble on the Ridge is a take on the traditional Backyard Ultra-Last Person Standing. The event takes place on an old family dairy farm just 40 minutes west of Madison, WI in the heart of the Driftless Area. Participants will compete on a 1"ish" mile looped course, dubbed "The Drifty Mile", completing a loop every 20 minutes. Sounds easy enough right?....
To keep it interesting we change the route up every year and will not publish details until the day of the event. All we can tell you is it will be between 1-1.25 miles, there will be a minimum 250ft of elevation gain, and you will have 20 minutes per loop. The rest you will just have to show up to find out. The race goes until only one person has successfully completed every loop in under 20 minutes. We do have one more catch..... the route reverses every 4 hours so you can never get too comfortable.

The Driftless Trail
Driftless Endurance will donate $0.10 for every lap completed during the event to the planning and building of the Driftless Trail. The Driftless Area Land Conservancy (DALC) is leading this project to build the Driftless Trail which is a planned 50-mile loop that connects Tower Hill, Governor Dodge, and Blue Mounds State Parks. This is a foot-only trail, to be used for hiking, running, snowshoeing, or cross country skiing wandering through the woods, prairies, farms, bluffs and streams of Iowa County’s Driftless landscape. Participants have the option to add a donation to DALC during registration if they choose.
More information on this project can be found on the DALC website.
Camping and Lodging
Camping will be allowed on the farm on Saturday night ONLY!! This must be a tent or camper van as this is a private residence and there are no camper hookups or space for parking pull behinds or RVs. There are several camping and lodging spots within 20 minutes of the race venue for Friday night.
