Welwyn Half Marathon and 10k
Welwyn Half Marathon and 10k start and finish on the 400m athletics track at Gosling Sports Park in Welwyn Garden City. The half marathon leaves the stadium, passes through the leafy outskirts of Welwyn and follows the Cole Green Way, a traffic-free former railway path, with a short loop before returning to the track for the finish.
- Half marathon 21.1 km route via Welwyn outskirts and Cole Green Way
- 10k multi-terrain course sharing the first 5 km with the half marathon
- 400m Fun Run free children’s track event with on-the-day registration
The 10k follows the same opening section as the half marathon, then branches onto its own loop back to the stadium. A free 400m fun run for children takes place shortly before the main races; parents may join. The day includes a warm-up led by personal trainers and a professional commentator at the finish. Food and drink are available from caterers.
The event is licensed by UK Athletics and is chip-timed by Event Chip Timing. Every finisher receives a custom-designed medal, free professional race photos, and a selection of snacks and goodies. The organiser works with Alzheimer’s Research UK as a charity partner. Transfers to a future ATW event are permitted but refunds and transfers to another person are not; transfers can be made up to 48 hours before the original event.
