About the event

Brecon to Cardiff Ultra Marathon
The Brecon to Cardiff Ultra is a 70km, point-to-point, fully marked race that follows the stunning Taff Trail from the heart of Brecon all the way to the Welsh capital. A firm fixture on the ultra-running calendar, it’s the perfect choice whether you’re tackling your first ultra or chasing an early-season PB.

Your journey begins in the breath-taking Brecon Beacons National Park, surrounded by dramatic mountain scenery. From there, the route take in trails past tumbling waterfalls and crystal-clear reservoirs before heading south into a landscape shaped by Wales’s rich industrial heritage.

The opening 30km features scenic footpaths and forest trails, before reaching the halfway checkpoint at Merthyr — an ideal spot for a shoe change. From here, the terrain transitions to an off-road cycle path that carries you smoothly (and downhill) to the finish in Cardiff.

Your Entry Includes:
Participation in a classic, well-loved ultra
Electronic timing & live GPS tracking
Fully marked course
Checkpoints stocked with refreshments & hot food
Halfway drop bag service
Finisher’s medal
Free professional race photography by the legendary Tosh
Free car parking at the Cardiff finish
Coach transfer from Cardiff to Brecon on race morning
Comprehensive emergency first aid cover
And of course… a taste of true Welsh winter weather!
