15th Anniversary Event
October 4th and 5th 2025
Our sport continues to grow, and one of the latest trends is to up the ante a bit by adding the challenge of completing a “series” of events. So Wheeler Event Management and Progressive Racing Productions have joined forces to present Mickelson Triple Dog Dare. If you complete either the half, full, or relay marathon at Deadwood Mickelson Trail Marathon in early June; any of the distances of The Lean Horse 100 in August (30K, 50K, 50 mile , 100 mile and 100 Mile Relay); and either the half, full, or Relay at Run Crazy Horse in October you will earn your choice of a Triple Dog Dare exclusive merchandise item!
If this sounds a bit daunting to some of the I-can-only-do-one-big-race-a-year runners, we’ve got you covered. Invite some of your craziest friends to join in! Giving you the opportunity to train together, travel together and brag together.
So join us for the Mickelson Triple Dog Dare by signing up for all 3.
Just running each individual race does not qualify you for the Triple Dog Dare swag. You need to register for the Triple Dog Dare specifically. You must register for the Triple Dog Dare on the Deadwood Mickelson Trail Marathon Registration page. There is a question on the form “do you want to complete the Triple Dog Dare?” Answer yes (the default answer is no)
Free! You will just need to register for each race separately. Links are below.
Stop by the awards tent at the finish of Run Crazy Horse to pick up a free Triple Dog Dare finisher item.
