ATW Welwyn Half Marathon

About this event

The Welwyn Half Marathon and 10K bring runners to Hertfordshire's autumn landscape for a race that starts and finishes on Gosling Sports Park's professional athletics track. The half marathon winds through leafy neighborhoods before joining the Cole-Green Way, a former railway line that's now a peaceful, traffic-free running path. The 10K follows the first 5km before looping back, offering a shorter option that still captures the route's character. Both distances benefit from chip timing and a UK Athletics license, with warm-up sessions led by personal trainers before the start. The finish line atmosphere keeps the energy high with a professional commentator and on-site catering to welcome runners home.
