The Event
Join us at this popular event taking place at Henley Leisure Centre and within the grounds of Gillotts School.
Henley-on-Thames is perhaps best known for the annual Royal Regatta, which attracts some of the world's finest rowers.
Conveniently situated just outside the picturesque town of Henley, on the edge of the Chiltern Hills & the banks of the River Thames and boasting a spectator-friendly course, the Henley Triathlon is one not to be missed.
There will be facilities available at the event including hot and cold food, refreshments, toilets and a large grass area ideal for family picnics and kids to play that all make for a great day out for the family!
Places are sure to fill up quickly, so secure your place and enter now.

Do you have children that can't wait to become a triathlete? Make a weekend of it and enter them in the Henley UK Kids Fun Triathlon on Saturday for 5-16 year olds.
The Kids event has been over-subscribed for the last few years resulting in entries closing early, so be sure to avoid disappointment and book early.
Due to the venue being a school playing field, dogs are not allowed on the site.

HOW IT WORKS
A relay team can consist of two or three people.
Each member of the relay team completes one or two of the three disciplines in the triathlon.
The swimmer completes the swim, then the swimmer passes the electronic chip to the cyclist inside the cycle transition area.
The cyclist completes the cycle course and passes the electronic chip to the runner in the transition area.
The runner completes the run and hands in the electronic chip at the finish line.
All team members can cross the finish line together and collect their medals.
Awards
We award first place in the Female Relay Event and first place in the Open/Mixed Category Relay Event.
All Open/Mixed Category teams can consist of two or three people, male or female.
