Swim. Bike. Run. Or Just Swim and Bike. Or Bring a Team. Wales' Toughest Coastal Triathlon Returns to Broad Haven.

The Pembrokeshire Coast Triathlon brings a full field of triathletes to Broad Haven, a stretch of golden sand at the southern end of St Brides Bay in the Pembrokeshire Coast National Park. Race the full standard distance triathlon (1.5k open water swim, 42k bike, 10k run), take on the swim-and-bike Aquabike, or split the distance across a relay team of two or three.

This is a serious test — the bike course climbs over 400m through rolling Pembrokeshire lanes, and the run's opening 3k along the Pembrokeshire Coast Path adds another 130m of climbing, with sweeping views over St Bride's Bay before you're back on the seafront. The event regularly forms part of the Welsh Triathlon Super Series (broadcast on S4C) and has hosted the Welsh Standard Distance Championships, so expect a genuinely competitive field alongside plenty of first-timers.

❤️ Support the Boardwalk

This year's race is once more raising funds for Support the Boardwalk.

The Course

Swim (1.5k): a rectangular open water course close to shore, never more than 200m out, at Broad Haven. Sea temperature is typically 14–16°C on race day, so wetsuits are likely to be compulsory

Bike (42k): mainly rural Pembrokeshire roads with over 400m of climbing, plus some fast flat sections on the final stretch from Haverfordwest back to Broad Haven. Roads stay open to traffic throughout, so normal road rules apply

Run (10k): starts with 130m of climbing along the scenic Pembrokeshire Coast Path, with views over St Bride's Bay, before quiet country lanes bring you back to the seafront at Broad Haven for the finish
