ATW Welwyn Half Marathon and 10k

The ATW Welwyn Half Marathon and 10k takes place in Welwyn Garden City, starting and finishing on the 400m athletics track at Gosling Sports Park. The event is fully licensed by UK Athletics and utilizes professional chip timing to ensure accurate results.

Participants can choose from several distances:

  • Half Marathon (13.1 miles)
  • 10 km
  • 400 m Fun Run

The half marathon course leads runners out of the stadium through the outskirts of Welwyn before joining the Cole Green Way. This section follows a disused railway line that provides a traffic-free path. After a short loop, the route returns along the same path, concluding with a final lap of the athletics track. The 10 km race is a multi-terrain course that shares the first 5 km with the half marathon before following its own loop back to the stadium.

A free 400 m children's fun run is held on the track shortly before the start of the main races. Registration for this activity takes place on the day of the event. Before the races begin, personal trainers lead a warm-up session. A professional commentator greets runners at the finish line, where every participant receives a custom-designed medal, professional race photos, and a selection of snacks.

On-site facilities include quality food and drink caterers for spectators and participants. Limited paid parking is available at the venue, with further parking options located in the town center. Visit the organization's website for the most recent information.
