ATW presents the Bristol Triathlon, one of the UK's most-popular 'closed-road' Triathlon events, in a vibrant city known for its culture, creativity and green spaces.

The race is based around Bristol Harbour, starting with a swim in the Cumberland Basin, followed by a traffic-free ride on Portway under the famous Clifton suspension bridge and to round it off, an epic run alongside the River Avon.

Whether you are a novice cyclist enjoying the traffic-free route, or a serious athlete looking to post a PB, this 'closed road, traffic-free' event will be one you will remember.

This is a mass-start, non-drafting event with start waves through the morning from 7am, with two distances to choose from:
- Sprint - 750m Swim - 22km Bike - 5km Run
- Standard - 1500m Swim - 34km Bike - 10km Run

If you dont want to tackle all three disciplines yourself, there is also an Aquabike (Swim-Bike) on offer for both distances and a relay over the Standard distance.

This event is for athletes of all abilities and ages.

Following on from the public races, there will be a chance to watch the British Triathlon Elite Super Series from 12pm, showcasing the best of Britain's triathletes, making this a day of triathlon action that is not to be missed.
