Event overview

The ATW Welwyn event at Gosling Sports Park in Welwyn Garden City offers a half marathon and a 10k, plus a short children’s fun run. The course starts and finishes on the 400 m athletics track. The half marathon goes out of the stadium, follows routes through the outskirts of Welwyn and onto the Cole Green Way, then returns to finish with a lap of the track. The 10k shares the same opening 5 km as the half marathon, then follows a separate loop back to the stadium.
