Start your race with the exclusive opportunity to swim in Cardiff Bay. Cardiff Bay is supplied by two rivers to form a 500-acre (2.0 km2) freshwater lake around the former dockland area south of the city centre. You will swim across the bay to the bottom of transition.
Your bike route is TBC, but will heading out of transition under the shadow of the Wales Millennium Centre and be a lapped course on the flat roads around Cardiff Bay area.
The run is a fast two loops of an out and back run route, showing off the sights of Cardiff Bay along the way. Heading out of transition first towards the Norwegian church and along the cycle path, taking in the sites of industrial heritage that Cardiff is so renowned for. The route is flat and fast especially as you run along the Barrage. The route back gives you views of the Pierhead Building, the Wales Millennium Centre, the Senedd and you’ll have plenty to keep you motivated as you go for that place on the podium and at the World Championships! Once you get to the Senedd Building it's time for your sprint finish; along Bute Place, around the corner and into the finish line in front of the Wales Millennium Centre.
(Bike route to be confirmed.)
In the interest of athlete safety and the safety of our volunteers on the course, there will be strict cut-off times in place.
Timings are subject to change. Confirmed timings will be detailed in your final instructions which are emailed to athletes 10 days prior to the race, and they’ll also be available 10 days prior to the race online.

The Sprint distance was my first ever triathlon. I'd definitely recommend this event to anyone, and I've already entered for next year's Olympic distance. David J
This is my 3rd Cardiff Tri at Standard distance and again it did not disappoint... It’s my hometown race and once again, I’ll still come back next year. Eleanor P
This is a very fast course with a pan flat bike and run course. The swim is also very simple... Sam A
Great event. Wanted to take part in this because of its sheer size. Glad I did it was brilliant. Darren V
Last year's Sprint was my first attempt at triathlon. I loved it so much, I entered this year's Olympic distance the following week. David J
The event itself was absolutely amazing! Loads of support even on a rainy day and the transition area in Roald Dahl Plass just made it even more special. The Swim was excellent and really fast in the calm waters of Cardiff Bay. Chris W
Loved Cardiff Tri - completed as my second Olympic distance. Registration day before was nice and easy, good set up of stalls to grab some clobber and we got socks, a cow bell, foam hand and energy bar on sign up. Sarah W
I wouldn't hesitate to recommend this one. A well organised event with a super friendly events team. Victoria W
