The Chepstow Running Festival, taking place on Saturday, 16 August 2025, is a vibrant summer event held at the iconic Chepstow Racecourse in Monmouthshire. Participants can choose between three scenic race distances—5K, 10K, and Half Marathon—with all routes following a traffic-free, undulating loop around the historic horse racing track. The 5K involves one lap, the 10K two laps, and the Half Marathon covers four laps, each supported by clear signage, chip timing, and an enthusiastic team of marshals. Runners of all abilities are welcomed, from first-timers to seasoned racers, and every finisher receives a unique medal, professional race photos, and post-race refreshments. With a festive atmosphere and stunning views along the Welsh-English border, it’s a perfect summer race-day experience for individuals, families, and running clubs alike.
