Event overview
Starting alongside Cardigan Bay on the golden sands of Abersoch beach, the routes follow the coastal path past Tudwal’s Islands, Porth Ceiriad, and for the 20K, right out to Porth Neigwl (Hell’s Mouth), looping back round to finish Abersoch Beach again.
Apart from enjoying the most mesmerising views, both routes offer exciting terrain, with tracks and trails for most of the route, a little bit of road and Abersoch’s famous beach thrown into the mix. By starting and finishing on the beach, these runs make more of this stunning location for the hub of the race, with more entertainment and activities for your post-race experience!

I love everything about this series. Friendly atmosphere, large crowds around the course, beautiful scenery and the finish is on the beach. They all combine to make each race special. Superbly organised and great finisher medals. Rhian R
Stayed the weekend, very well organised event, and huge numbers of spectators cheering me on from start to finish. Wife and kids also had a great day on the beach rounding it off as a perfect day. Alun V
A race I always look forward to as the course is so unique due to its challenging terrain, spectacular views and memorable finish along the beach! Jane E
