Description

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.

Sprint competitors complete 2 laps of this super fun and speedy 9k course on closed roads. Heading out of transition under the shadow of the Wales Millenium Centre you will head along James Street and down Ferry Road. You will turn around at the Morrisons Supermarket roundabout and fly back up the road the way you came. You will then head along Lloyd George Avenue and thrill at the speed on this section, with another turn around to come at the top so that you get to fly down the avenue once again. The lap ends at the entrance to the Oval Basin and a the Wales Millenium Centre.

The Sprint run is a fast 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 Millenium Centre, the Senedd and so much more that you’ll have plenty to keep you motivated as you go for your PB! Once you get to the Senedd Building its time for your sprint finish; along Bute Place, around the corner and into the finish line in front of the Wales Millenium Centre with a famous Always Aim High welcome.

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
