Starting alongside Cardigan Bay on the golden sands of Abersoch beach, the routes follow the coastal path past Tudwal’s Islands, Porth Ceiriad and and for the 20km, right out to Porth Neigwl (Hell’s Mouth), looping back round to finish back at Abersoch Beach.

This race is part of the Abersoch Triple Crown series which includes the Abersoch 10K and the Abersoch Triathlon.

2025 also includes the 2km Beach Blast for the younger runner, or those who prefer a shorter distance.

On the evening before the races is the 2.2km Torchlight Beach Run with 100% of the entry fee going to the Menter Rabar community. Bring your torches, glowsticks, anything that will light you for a feel good 2.2km run to the far end of the beach and back.
