By Car
The major road route into Cardiff is the M4 motorway. The Cardiff Triathlon Registration and Event Village are conveniently situated a few hundred meters from the A4232 expressway and less that 30 minutes from the M4.
From the East or West: Visitors travelling along the M4 from the West are advised to leave the M4 at junction 33 and join the A4232. If you remain on the A4232 it will eventually lead you to Cardiff Bay.
From the South West: Visitors travelling from the South West of England should head North along the M5 motorway and then follow signs for South Wales and the M4.
From the Midlands and North: Visitors travelling from the Midlands and the North of England should head for the M50 motorway (junction 8 on the M5 motorway) and then onto the A40 (signposted South Wales, Monmouth). Continue along the A40 until you reach Monmouth when the road becomes the A449. Continue along the A449 until you reach the Coldra roundabout where you should take the 5th exit to join the M4.
By Train
You can reach Cardiff city centre by train from virtually any location within the UK.
For visitors travelling from London, Great Western Railway (GWR) operates an hourly train service from London Paddington and the total journey time is just 2 hours.
From Cardiff Central you can catch another train to Cardiff Bay Station which is less than half a mile away from the Event Village. There is also a shuttle service (Cardiff Baycar, service No 6) which takes just 8 minutes to arrive outside Wales Millennium Centre. The Baycar runs every 10 mins. Taxi and Bus services also operate to and from Cardiff Central and Cardiff Bay station.
The event organiser would recommend The Future InnsExternalLink in Cardiff Bay which is literally a stones throw from all the action. The Future Inns is a bike friendly hotel, so you can cuddle up to your beloved all night long. They will also offer you an early breakfast on race day so you're guaranteed to be well looked after.

Did the Olympic in 2022
The start time and cut-off times to be out of transition etc. seemed far too early.
Did the Olympic in 2022
You guys rock!
Did the Legend in 2022
The course was rough on the tarmac and had lots of ruts and obstacles to avoid. As a legend competitor it was very busy with other events which was nice but at a time challenging in some spots
Did the Sprint in 2022
The route wasn’t sign posted very well which resulted in me doing an extra lap then I should of which cost me a top 5 finish. When asked the staff for help they wasn’t very helpful as one of them pointed me the wrong way and the other didn’t know how many I was supposed to do for my event
Did the Sprint in 2022
The course wasn’t posted very well which resulted in me doing an extra lap and costing me a podium finish. The staff wasn’t helpful and missed informed me on how many laps I was meant to do after I forgot.
Did the World Triathlon Age Group Qualifier & British Championships in 2022
A great event
Did the Sprint in 2022
Well organised but not much atmosphere around the course! Good around the transition/finish area though!
Did the Super Sprint in 2022
I really enjoyed the triathlon, I would recommend it to anyone who has never done a tri before. The cycle and run was lovely and flat, the swim was a little choppy and and I would recommend doing some fresh open water swimming before the event.
Did the Olympic in 2022
Great experience, fantastic views
Did the Sprint in 2022
Can I say a big thank you to all the Marshalls . It was my first tri and sadly it went very wrong on the bike . I had a puncture at 12k so I had to be picked up by the bus . I was also one of the last riders mainly as I thought mountain bike won’t be that different to a road bike . However I was gutted at the thought of not doing the run and I was allowed to do it . This meant the world to be as I was never going for a time but it meant I’d somewhat done the three events. Although I haven’t got a time on the official results for me it was about completing it so thank you for allowing me to do the run. Next year I may be back with a puncture repair kit on my bike . Thanks again xxx

Hi there, I’m interesting in doing the Cardiff Triathlon (Sprint) and wondered if there are rules about which bikes you can and cannot use for the cycle? I really would like to use my Brompton folding bike which is perfectly fine but wasn’t sure if there were rules about the models being used. Best wishes, James
