Join the CRUK Wave

The Henley Triathlon is also part of the UK Triathlon CRUK Wave, a  wave dedicated to raising money for CRUK. The CRUK Wave is aimed at encouraging more participants, of any age, gender or ability, to unite and take on a challenge for the purpose of funding life-saving research into all 200 types of cancer. 

For each CRUK Wave entry, UK Tri donates £10 (incl. VAT) to CRUK. This can have a huge impact – did you know that 10 CRUK Wave entries could cover the cost of testing one patient to diagnose early stages of oesophageal cancer? 

Join CRUK right now and we'll get you to the finish line. We've got training and fundraising advice to prepare you for the big day, cheering packs for your friends and family, and a dedicated team ready to answer any last minute questions.
