The ATW Bristol Triathlon just got even better! We’re introducing a University wave, inviting local university students to take on this epic closed-road triathlon in the heart of Bristol. 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 starting at 08:00.  Standard - 1500m Swim - 42km Bike - 10km Run

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.
