Welwyn Half Marathon – Sunday 27th February 2022

Welwyn Half Marathon


The Welwyn Half Marathon starts and finishes on the 400m athletics track at Gosling Sports Park. You will be directed out of the stadium, towards the Cole Green Way – a disused railway line which is now the perfect track to run along. After this traffic free section you will complete a short loop to bring you back onto the Cole Green Way again. You then complete the first section in reverse and finish with a track finish at Gosling Sports Park.

Taking place at the end of February this is also a perfect preparation race for anyone taking part in a Spring marathon.

This race will be operating a 3 hour cut off time, after which there will not be marshals and course signage available.

We are pleased to be able to give you the opportunity to complete a half marathon distance in a small scale, friendly environment. The race will be held under a full UK Athletics race license and be officially chip-timed by our professional timing partner, Event Chip Timing.

The race will start from 09:00am in a rolling-start format with athletes aiming for the fastest predicted times and the race win, leading the way. This format will avoid any bottlenecks from forming as you leave the stadium.

There will also be the Welwyn Micro Marathon around the Gosling 400m athletics track, for kids which will be free! This always creates a fantastic atmosphere before the start of the main event.

The course has traffic free sections, however any sections which are not, will be well marshalled, so you can be assured that the course is fast.
