ATW Welwyn 10K

Event overview

Taking place in September, it's a perfect time for a half marathon!

The course is accurately measured and held under a full UK Athletics race license. The race is chip-timed by our professional timing partner, Event Chip Timing and your results will appear on PowerOf10.

This event is more than just a run. You’ll be warmed up with personal trainers, welcomed home by a professional commentator and your cheer-squad will be kept fed and watered by quality caterers while you run.

Running with friends or family? Purchase a Group Saver Ticket (minimum 2 people, max 10)

A free 400m Children’s Fun Run will also take place on the running track 15 mins before the half-marathon start (no need to book, just turn up to registration). Parents are welcome to run with their kids and use it as a warm-up for the main event!

Run this race every year and it is a brilliant out and back course that finishes on the running track allowing you to have your own Olympic moment. James M

Great event great atmosphere - enjoyable course. Thank you. Sam B

Good event, well marshalled by local running club. Really good quality T shirt, which came as quite a surprise for the modest entry fee. David S

My 4th ish Welwyn Half Marathon. As usual, the event starts off at the Gosling athletics track, and really pleased that the organisers have listened to feedback and you now run more of the track, which is a great exciting start to the race. Also the family fun run at the start is an excellent idea, more races should do this - my kids loved it. Well sign posted throughout, and a mix of different surfaces, with a couple of gradual gradients, make this a more challenging than your run of the mill pavement half. Really good race for local runners. James D
