ATW Welwyn Half Marathon

Step into the vibrant Welwyn Half Marathon and 10k on October 3, 2027, where runners start and finish at Gosling Sports Park's impressive 400m athletics track. The half marathon route ventures through Welwyn’s leafy outskirts before taking you onto a serene traffic-free path along Cole-Green Way, an old railway line now transformed into a runner's paradise. After completing a short loop back to this scenic stretch, runners reverse their course and return to the finish line at Gosling Sports Park.
Running in autumn offers cool temperatures and crisp air, making it ideal for distance racing. The race is licensed by UK Athletics and features professional chip timing from Event Chip Timing. With a 3-hour cut-off time, participants can enjoy safety and support throughout their run. Pre-race warm-ups led by personal trainers and post-run commentary add to the event's atmosphere.
The day also includes a free 400m Children’s Fun Run on the track at Gosling Sports Park starting at 9:15am, allowing kids and parents alike to enjoy some pre-event fun before the main race begins.
