Why is the Blenheim Palace Triathlon THE event for you and your colleagues?

The Blenheim Palace Triathlon is the UK’s second largest triathlon and the only triathlon in the world to take place in a world heritage site, each year welcoming over 7,000 participants of all ages and abilities to swim, bike and run around the spectacular route. After 2019’s sell-out event, we look forward to welcoming yourself and your company in 2020.

Over 30 companies took part in 2019 with over 700 participants. These companies and many more return each year to the event because it is a fantastic way to promote health, wellbeing and friendly competition in the workplace as well as providing an excellent focus for corporate charitable fundraising. The Blenheim Palace Triathlon also provides your company with the option to purchase a Corporate Hospitality Marquee along the finishing straight.


Held in the stunning grounds of Blenheim Palace, the event is a great opportunity for individuals and teams from companies of all sizes to come together outside of the office and take on a challenge together.
