Endeavour Swanbourne is a gutsy, grueling off-road endurance event that allows you to plunge into the wilds of Buckinghamshire - streams, woods, fields, haystacks, fire - for a cross-country endurance race that will push you to the limit and beyond. A test of determination spirit and camaraderie, but above all spirit. Spirit is everything.
This is an event for all fitness levels, but you won't find it easy. From the 5k Kids' Endeavour, to the 5k adult event and the tougher 10k, there's something to challenge the young and the old. Many have felt the accomplishment of running, climbing, crawling and dragging themselves round the course.
