Now in its fourth year, Merrell’s Down & Dirty Obstacle Race is coming to Atlanta on October 12th 2014. You can choose to compete in either three or six mile  races, but both are packed with military style obstacles to test you to the limit!

Runners will gather at the Georgia International Horse Park, and will wind through local wooded areas and into the Olympic mountain biking course, with its tricky rocky terrain, before crossing the river and into the mud crawl.

The race costs $75 or $85 to take part in, depending on whether you fancy the three or six mile event, and you can register for the Atlanta Down & Dirty Mud Run right now. Races depart between 8:30 and 10:30am.

The Down & Dirty Mud Run is going to be venues across the United States throughout the year. Here’s the full schedule:
