gnaw bone shirt and medal

For those of you unfamiliar with Brown County, Indiana, the terrain will bring you shock and awe! Vicious 600’ ridges, breathtaking natural beauty and wicked trails abound. Gnaw Bone is about one mile out of Nashville, IN, an artisan community with over 200 galleries. A picture postcard of a town and definitely worth a visit, just 3 miles from the race start.

All entries include a custom technical gender specific fit t-shirt and finisher medal (Finisher medal will be a handmade laser cut steel)! Overall awards to first male and female in all distances. Age group awards 3 deep in all 5 year age groups for all events!

Home of the the world’s most difficult 10K. Expect double your road time and triple the effort!

Note: The other race distances, 5K, 13.1M, 26.2M, 50K, and 50M are … We might say, “challenging”, so as not to scare you off, but then, we’d be lying! Come join us at the bone and see what you’re made of.

The Dirt Crew, at your service and doin’ it in the Dirt, just for you!
