Westport Triathlon — National Series

The Westport Triathlon is a Triathlon Ireland National Series event held on 15 August 2026 in one of the most scenic towns in the west of Ireland. Offering Olympic distance (1.5km swim / 40km bike / 10km run) and Super Sprint (400m / 20km / 5km), the race features a sea swim in Clew Bay, a bike leg to Croagh Patrick, and a run along the Westport Greenway.

The swim is in Clew Bay — a large sheltered Atlantic bay dotted with islands. Water temperature in August is typically 15–17°C. The bike course is an out-and-back to Croagh Patrick (Ireland's holy mountain) — mostly flat with some rolling sections and stunning views across the bay. The run follows the Westport Greenway, a converted railway line that provides a flat, scenic off-road running surface. Westport Triathlon has a reputation as one of the best-organised and most enjoyable events on the National Series calendar. The town fully embraces the event, and the post-race atmosphere in Westport's famous pubs and restaurants is a highlight. The Super Sprint makes it accessible to first-timers, while the Olympic distance attracts serious National Series competitors.

Registration through the Triathlon Ireland race calendar at app.triathlonireland.com. Olympic individual: €80. Super Sprint individual: €60. Relay teams: €90–€120. Triathlon Ireland licence or ODM required. The event is popular — register early.

Westport is in Co. Mayo — about 3.5 hours from Dublin via the M4/N5 and 1.5 hours from Galway. The town has excellent accommodation: hotels, B&Bs, and holiday homes. August is peak tourist season in the west, so book well in advance. Westport train station is on the Dublin–Westport line (3.5 hours, scenic route). Event parking is available near the race venue — check the event guide for specific locations.

The Westport Triathlon is one of 18 rounds in the Triathlon Ireland National Series. The Dublin City Triathlon (August) is the next major National Series event a week later. For a longer race in the west, the Hardman Waterville Half (July) or the Gaelforce Great Fjord Swim (September) offer endurance challenges. The Tribesman Triathlon (June) in Galway is the nearest National Series race earlier in the season.
