Phoenix Park was buzzing with energy on Saturday morning as over 1,000 athletes took part in the RDJ Dublin City Triathlon 2025. More than just a race, the event is about challenging limits, setting new goals, and celebrating every achievement, no matter the size.

Hosted by the Piranha Triathlon Club, this flagship premier multisport event offers something for everyone, with Sprint, Standard, Try-a-Tri, and Aquabike formats designed to welcome both seasoned triathletes and first-time participants.

A highlight of the day was the Corporate Relay Challenge, where nearly 60 teams competed in a dynamic course featuring a 750m swim, 20km cycle, and 5km run, bringing team spirit and friendly competition to the forefront.
