The North Downs provides a fabulous backdrop to an incredible challenge with 50km, 25km, and 10km options to push yourself further. Walk, jog, or run across the best trails in Surrey all whilst fundraising for a cause. Head out from basecamp in Guildford along the North Downs Way and up to a spectacular view at St. Martha’s Church. Full 50km Challengers then head back towards basecamp through idyllic villages and the scenic Blackheath Common. This Challenge is easily accessible from London with excellent transport connections – the perfect Ultra Challenge for all!
