Organiser's Description

UPDATE 20th March - medal entries are now SOLD OUT! Thank you! No-medal entries are available.

Phoenix Running South Wales invites you to celebrate our 1st Birthday with us as at CAKEATHON on Sunday 29th March 2026.

This is one of our timed events where you choose how far to go - from 5km to 10k, half to marathon to ultra, you can complete as many, or as few, laps as you like of a 5.3km, 3.28 mile, out and back, course through Parc Taf Bargoed, a Green Flag park offering visitors access to an area of exquisite beauty and spectacular views shaped by the area's industrial past and recent redevelopment.

We welcome runners and walkers alike. Complete one lap, and you're both a finisher and a winner in our eyes or keep going and see how far you can get in the full 7-hour time . Everyone gets the fabulous bespoke finishers medal. There will be cake!

We operate our uniquely flexible rock up and run start times, so there is no waiting around if you arrive early and no added pressure if you're running a bit late. If you have any special start time requirements, get in touch, and depending on the distance you plan to run, we will try to accommodate all start time requests.

Not sure?  Well, the beauty of this format is that you don't even need to decide in advance - simply come and run a lap and see how you feel on the day and keep on going if it feels right.

Places will be strictly limited so don't leave it too late to enter.
