We are the team behind Pegasus Ultra Running, Wild Horse 200 and Epona 100.
We’ve been working in the ultra trail running industry since 2012 and competing in events since 2010. This isn’t our first rodeo and it won’t be our last.
Our goal is to make Sirona 100 the gold standard of 100 milers in Wales. Taking all the good stuff, phasing out the bullshit and just putting on a proper tidy event that welcomes everyone with a smile and a cwtch… Google it if you’re not sure, a good excuse to learn some Welsh – it’s a great language.

The Epona is a tough event which you would expect for a 100 miler but the payoff is out of this world.
The views on the course are simply breathtaking but this pales next to the complete support of Rhys and the rest of the crew. I felt special at every single moment of this race right from the pre race phonecall, registration and pre race briefing through every checkpoint and right to the finish line, nothing was too much for the crew no matter the time of the day.
