Clapham Common 5k, 10k & Half Marathon September

The Clapham Common 5k, 10k & Half Marathon is a September RunThrough race held on Clapham Common in south London. All three distances are contained within the park, avoiding city streets. The half marathon begins first, with the 5k and 10k starting half an hour later. This allows runners to select a short, quick morning run or a longer, multi-lap course. The route follows mostly flat footpaths within the common and goes past the Clapham Common Bandstand. Each kilometre is marked with distance flags, and helpers are stationed around the course. The setup is suitable for runners aiming for a personal best, as well as those seeking a simple park race. Entry covers chip timing, complimentary race photos, water, post-race items, and a themed medal.
