Organiser’s Description

A classically simple but rather testing, muddy, lumpy, hilly and challenging, out and back multi-terrain course from Dorking, over the Greensand hills of Surrey. ”One of the true great trail marathons in the UK”. From 2015 the Marathon will take place only in odd-numbered years; the Half Marathon will take place each year.
