Waves Mud and Mountains is back! Following a superb turnout for our winter edition in November 2019, your favourite multi terrain obstacle race event will be back for a September 2021 outing.

Our challenging circuit pits competitors against the legendary natural elements of the Conwy Valley. Distance-wise, it’s around 8.5km, but this intense course will test your stamina, agility and mental strength to the max.

Once you’re over the line you can join us for some post-race R&R in our surf-side bar. There will be a complimentary beer or soft drink for every competitor and our usual buzzing post-race atmosphere.

Unless you know how to walk on water, you’re going to be running through our waves. That means pushing against the power of 6 million gallons of watery opposition over 300 metres to get to the other side of our lagoon.

This is where things get a bit messy. Once you’ve made it across our lagoon you can warm up with a short run through our forest trail to our obstacle field. You’ll be faced with a whole lot of mud and a variety of challenging obstacles.

Brace yourself. This is where you’re going to need a bit of grit to get you over the finish line. The last stage of your race is a run up the notoriously steep Dolgarrog Water Pipe incline. Just don’t look up. But rest assured you’ll enjoy looking down (once you’re at the top). It’s just a short and scenic downhill run back to the lagoon-side finish line. What a triumph!
