Richmond, West London, and 000's of excited Challengers eagerly await their start in the tented village. There’s 100km of trails ahead, over 60% of it off-road, with some wonderful countryside before the final climb over the South Downs with the coastline in view view at last - and the welcome finish line awaits down the home straight of Brighton Racecourse.

Whether you're a walker and new to endurance events, or even a marathon runner looking to 'up' the distance - you'll get the best support and hospitality through day and night. The Full 100km, with 1,500 metres of climb, can be done as a continuous Challenge - or as a 'Daylight 2 Day' option with camping at halfway. With Half and Quarter distance options available - there's a Challenge here for all.
