Only The Brave takes place at Thetford Forest and is celebrating its fifth birthday, at the same time the charity celebrates its 20th anniversary.

To mark the milestones, the event, which last year saw nearly 2,000 runners take part, will see new obstacles including the kit carry bag challenge, 24/7 clock climb and the rotor scramble, as well as a new route through Elveden estate.

The popular race is set to take place on Sunday, March 29, and provides a six and 10 mile course, with 20 to 35 obstacles, lots of mud, slides, straw bales and challenging hurdles.

The event raises funds for EAAA, which operates operates two helicopters covering East Anglia every day of the year.

In February the charity launched a new campaign to raise an additional £1m annually to help them become a 24/7 service.

The charity will be offering an early-bird rate until the November 30.

Spokesman Catrina Miller said: "This obstacle course is for everyone and hosts competitive runners sprinting for the time, people who want to have a fun team day out with their friends or work colleagues, people who want to set themselves a challenge to people who want to just take part in a fun event and raise money for EAAA."The early-bird rate provides several options ranging from £25 upwards.

Every entry will receive an OTB official t-shirt, a medal and a goody bag when they finish the course.
