About this event

One True Grit events are a combination of running, mud and obstacles designed and managed by British Armed Forces. One True Grit is a hardcore 10k and 5K run across raw natural terrain, including open ground, woodland, lakes and thick mud. You'll tackle a series of seriously tough obstacles - both man-made and natural - designed to test your mental and physical strength, skill and stamina. You'll run, climb, jump, wade, crawl and swim through a course designed to challenge you on every level. We at One True Grit believe it is the toughest event on the planet.
