The 12 Hours of Acton is the newest and only race of it's kind in Eastern MT. Start time will be 10am and run until 10pm. For this inaugural year we're going to be doing two alternating loops around an hour each. Leaving from camp/aid station, soloist and teams will head out on a beautiful rolling loop of singletrack through sagebrush, forests, and sandstone formations. Each loop if roughly 4 miles and the goal is to run as many, or as little as you want in 12 hours. Their will be the normal aid station accouterments in camp as well as beer, burgers, and more. Camping will be available at the site and as there is no power or water, it is advised to bring a some portable shade and coolers to keep your goodies cool. I know i'll forget stuff so email me with any questions or like the FB page for weekly updates. Hope to see you all there this fall.
