The ATW Welwyn Half Marathon and 10K start and finish on the 400m athletics track at Gosling Sports Park in Welwyn Garden City. Both races head into the leafy surroundings of Welwyn, with the Half Marathon extending onto the Cole Green Way, a former railway line transformed into a traffic free route through the Hertfordshire countryside.
Half Marathon runners follow the Cole Green Way before looping back towards Gosling Sports Park. The 10K shares the opening 5K before branching onto its own loop and returning to the stadium. Both distances are chip timed and UK Athletics licensed, with clear course marking, supportive marshals and a final lap of the athletics track providing a distinctive finish.
A free 400m Fun Run takes place on the track before the main races, giving younger runners the chance to take part. Spectators, refreshments and finish line support add to the atmosphere, while the leafy surroundings, traffic free sections and stadium setting give the event a memorable character.
