The Epona 100 has always been about pushing limits - a full 100 miles across the wild heart of South Wales.

Now, we’re opening the door a little wider.

🔥 Introducing the Epona 100km 🔥

The same legendary course.
The same rugged Black Mountains.
A brand-new challenge in its own right.

The 100km distance is built for adventure - a bold step for those ready to test themselves, and the perfect gateway for runners dreaming of one day tackling the full 100 miles. Supportive, inspiring, and unapologetically wild.

Taking place on the same weekend as our 100 miler, the 100km will traverse the second half of the Epona route 🫶

Whether you’re chasing your first ultra milestone or stepping onto the Epona course for the first time, this is your invitation.

🌄 One course. Two distances. Endless possibility.

As the 2025 Epona 100 drew to a close this morning, the hills finally exhaled - humbled by the quiet determination of every runner, volunteer, and supporter who brought heart, humour, and grace to one of the wildest journeys on foot ⛰️

Through every high ridge and low moment, what shone brightest was the spirit of the community—resilient, generous, and a little bit wild in the best possible way 🫶
