THE ROYAL BRITISH LEGION MAJOR SOUTH
Be prepared to get seriously muddy with this extreme 5K and 10K obstacle course around the 3,000-acre Eridge Estate run by The Major Series instructors from British Military Fitness. This is not for the faint hearted: obstacles include deep stench trenches, balance beams, blockade walls, wobbly bridges over lakes and a freezing ice crawl, not to mention the steepest hills and the thickest woods.
Pre-booking essential: entrants on the day are not permitted
