The Findon Valley 5K & 10K is a Sunday morning running event held in October, beginning at Storrington Rise Car Park in Findon Valley, close to Worthing. The 10K race commences first, with the 5K starting soon after, requiring participants to select a single distance instead of completing both.
The 5K follows a hilly course, not a flat one: it departs the car park, crosses Cissbury Fields, reaches the vicinity of Coombe Rise Car Park, ascends towards Cissbury Ring, runs along the edge of the ring, and descends back to the starting point. Featuring 168 metres of elevation gain, it is suitable for runners seeking a brief yet challenging workout, and the event also accommodates beginners; the 5K route includes water and first aid stations near the 4 km mark by Nepcote Car Park.
