Major Series

British Military Fitness runs the award-winning Major Series Obstacle Race, which takes place up and down the country throughout the year. Voted the UK's 'Best Trail Race', the Major Series is the UK's most friendly obstacle race!

The 5k and 10k courses are littered with all kinds of obstacles, hills, mud and water. But, most importantly, are full of over 40 of the Major's finest troops, there to help you through the obstacles, but maybe challenge you to a few too!
