Most of the route follows footpaths across Clapham Common and passes the bandstand. This is a public park rather than a closed road, so you share the paths with walkers, dogs and cyclists, and the organiser advises against wearing earphones. The 10K has about 33 metres of climbing. Marshals, kilometre signs and arrows mark the way.
