About the race

The RUDUM 30 is a new single loop ultramarathon centred on Rudry in Caerphilly, Wales. It follows sections of the Rhymney Valley Ridgeway Walk and the Cambrian Way and explores the local hills of Mynydd Rudry, Caerphilly Common, The Garth and Cefn Orr. The event was created as a new version of the RIDUM to mark the organiser's 10th anniversary. The route crosses the River Taff and uses the Taff Trail at Nantgarw, climbs The Garth (307 m) and reaches ridgelines toward Cefn Orr (259 m).

A later loop visits Mynydd Machen (362 m) and Mynydd y Bwlch before returning to Rudry. The course accumulates 5,180 ft of elevation and runs over mixed surfaces including woodland path, trail, grass and some tarmac, with about 90% trail and 10% road. There are three checkpoints on course: two fully stocked aid stations and a midpoint water station that also serves as a drop bag point. Entries include no cut off times, a finisher medal, pre and post race care, a race manual, professional medical cover and support from The Teulu volunteer team.

A shorter option called the RUDUM HALF follows the latter part of the route. Organisers provide downloadable GPX route files via plotaroute.com to allow last minute updates and better navigation. Mandatory kit includes trail running shoes or hiking boots, waterproof jacket, 1 litre minimum water container, charged mobile phone, downloaded GPX route, head torch, survival bag, a reusable cup and a pack or race vest to carry equipment.
