Welwyn Garden City has fantastic sporting facilities and is surrounded by some great sporting clubs and associations. We are excited to bring this mass participation event to the area for another year. The race will be organised by Active Training World under UKA rules and will be hosted at Gosling Sports Park, Welwyn Garden City.



The route for the race is a mixture of a residential setting and a rural section along the Cole Green Way cycle path. The race will also start and finish on Gosling Running Track.

The route is best described as undulating but quick with many personal bests reported in 2015-2017. It will be an ideal final preparation race for London or other spring marathons.

Kids Event:

Before the race (8:40am) we will have a free kids event called the Welwyn Micro Marathon. This will be a single lap of the track and kids of any age can take part. They can run, be pushed in a buggy or carried around the track and all finishers will get a medal. You don’t have to enter in advance – just turn up on the morning!
