From the Organizer
This off-road marathon will be held at Red Lodge Mountain Resort. The Nitty Gritty is starting to earn quite the reputation. And that is, one nitty, gritty marathon with LOTS of climbing all on dirt roads and single track trails.
With a late August date, your summer of running and racing will be what prepares you for this “battle royal” event. Form a six, three or two runner relay team to tackle the marathon, or if you have the grit, try the solo hot lap, half, or full marathon!
The Nitty Gritty embodies our motto the most out of any race: low key, high elevation. While the terrain is challenging, everything else is lowkey and there is distance for all abilities. Dogs are welcome to run with you on or off leash, the beer and snacks might be the biggest draw….second only to the awesome people! Small but mighty, this race is for those who love trail running and everything that comes with it! Bring your bear spray, camp chair, and good attitude.
So lay the peer pressure on your friends, because its time to get down to The Nitty Gritty!
