The Cardiff Triathlon will play host to the standard distance race of the Welsh Triathlon National Championships in 2017.


Taking place on the 25th June 2017 at the Roald Dahl Plass, Cardiff Bay this is a truly unmissable event with a unique opportunity to swim in the iconic Cardiff Bay, cycle on completely closed roads and run the Cardiff Bay barrage. The finish line and transition is like nowhere else in the UK, situated on the Plass and directly outside the world famous Wales Millennium Centre.


To be eligible for a Welsh Triathlon Championship event you must be a member of Welsh Triathlon.
