The Dorset Ooser Marathon & Half Marathon are fully signed challenging trail races in the heart of Dorset by Badger Trail Events. 

We provide great support, first-aid cover, car parking, an entry fee that wont break the bank, toilets, free refreshment at the finish, medals for all finishers, and 4 aid stations.

We wanted hills, we were sure you would demand mud, and we knew you'd love a constantly changing route that will take you into parts of deepest darkest Dorset, via picturesque villages, old tracks, open fields, hidden holloways, ancient woodlands, and forgotten trails.
