The increasingly popular Henley-on-Thames Triathlon is in its ninth year and takes place at Henley Leisure Centre and Gillotts School.

The town 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 and the banks of the River Thame.

We want to encourage more women to have a go! Any age, any ability, just get together for the camaraderie and challenge, whilst raising vital funds for research into beating cancer. The event is aimed at all abilities, at all levels of fitness, from complete novice to club and pro triathlete, as well as charity and fun competitors.

UK Triathlon has dedicated a section of the event solely to The Pink Wave and is working in partnership with Cancer Research UK to raise money for research into all 200 types of cancer. Open to all women who want to take part. All abilities welcome. High 5's, cheers, and a lot of pink guaranteed!

Places are sure to fill up quickly, so secure your place and enter now.

The UK Kids Fun Triathlon Henley is now in its 8th year and held within the grounds of Henley Leisure Centre & Gillotts School, located just outside the pretty riverside market town on the River Thames.

Henley Triathlon routes

For the adult triathlon: The swim discipline takes place from the indoor swimming pool followed by the cycle course which is flat with some undulations and takes in many fields and trees in this rural route through the Oxfordshire countryside. The final run discipline is on grass around the picturesque grounds of Gillotts School.

For the kids triathlon:

The pool is 25 metres long, tumble turns are not allowed. Children will be started at 20 second intervals in the pool. The swim course is very straight forward and there will be a verbal briefing prior to each child starting. A swim cap will be given to each child and must be worn. Children may use their own swim cap instead if preferred.

The cycle course is fairly flat and on grass. The course is completely post and taped making it clear to follow and is entirely within the school grounds. Children will not be allowed to take part without a bike helmet.

The run is fairly flat and entirely on grass. The course is again completely post & taped and within the grounds of the school.The whole of the bike & run course will be post and taped, making it very easy to navigate for the children.

Parents/guardians, if you have a wristband, you are allowed into the cycle transition areas with your children to help them. The whole of the bike & run course is on hard compact grass, as well as being inside the school grounds, making it safe for the children.

    Interesting Course. Pretty hilly which adds an extra dimension. The pool was fine as long as you had your tactics right. I will definitely be doing it again next year!

    Did the Super Sprint in 2019

    This was my first Tri.
    It was a well organised event. It had a great relaxed, encouraging atmosphere.
  • Did the Sprint in 2019

    This was my first sprint triathlon. I thought it was really well organised with a great relaxed atmosphere. Everyone was really friendly and it didn't feel too competitive for a first timer. Everything went smoothly. The swim in the pool worked reasonably well for me as a reasonably slow swimmer, the cycle route was lovely and well signposted. The run - as four laps of a sports field was a bit tedious; it would have been nicer to do a circular route, but can understand why it is arranged the way it is. I enjoyed every minute of it. It was good to know that there were 2 transitions and to plan nutrition accordingly. I would definitely consider doing it again. Thanks to everyone who was involved in the organisation.

    Did the Sprint in 2019

    would have preferred an out and back run as running round the playing field is very hard work as its so boring. The event was overall marvellous. Loved the double transition as it avoids all the chaos. Bike ride was hard but good. Any chance of a single lap? I know its harder to marshall though so understand it may not be possible.

    Did the Sprint in 2019

    Very good course and event over all well signed for the cycle and run guidance from marshalls through out the event only thing that dropped the score and let down the day was the timing chip strap it came loose in the swim then came off just before the end meaning I had to stop then complete my last two lengths with it in my hand refitted in t1 for it to completely come off on the cycle again leaving me to stop and look for it not to find it other than that great day and event will definatly be doing it next year

    Did the Super Sprint in 2019

    Wonderful event! Very well organised with an absolutely lovely set of race volunteers and contestants! Everyone was so kind and supportive! Will definitely be coming back :-)
  • Did the Sprint in 2018

    As this event has two transitions, make sure to take a gel with you on the bike if you usually take one on the run - there won't be a place you can leave it in second transition if you don't have separate running shoes and bike shoes.Be prepared for things to get a little dicey in the pool - it's tiny and you will get held up as it's hard to overtake in such narrow lanes. Use those moments to catch your breath!
