You could tackle the bleachers, traverse walls and experience a rugby stadium like never before in the Allianz Stadium race in London, or maybe you'd rather combat fire, mud and water in a country estate in South Wales. There are plenty of locations to choose from as well as three different obstacle races, the Sprint, Super or the Beast.
