About Blenheim Palace Triathlon 2026
Join The Theatre's charity team for the Blenheim Triathlon on 6th June 2026
Swim, Bike and Run your way around the iconic Blenheim Palace grounds, a UNESCO World Heritage site. There's a choice of triathlon distances - each beginning with a sheltered swim in the Great Lake, a fast closed road bike course though the palace grounds and finishing with a scenic run through the Palace parkland.
There are distances for every experience level, whether its your first triathlon, or you're a seasoned competitor. You can also compete as a relay team of 2 or 3 people.
Saturday 6 June or Sunday 7 June
Sprint (750m swim / 19.8km bike ride / 5.4km run)
Sprint Team Relay Team for 2 or 3 people (750m swim / 19.8km bike ride / 5.4km run)
Super Sprint (400m swim / 13.3km bike ride / 2.9km run)
Family and friends can buy spectator tickets to explore the historic palace, stroll through the stunning grounds and cheer you on. The Theatre Team will also be there to cheer you on as you cross the finish line!

Why do we ask for a deposit?
Your deposit of £50 does not cover the cost of the charity entry fee for this event but it helps reduce the risk to The Theatre of people not fundraising or withdrawing from the event.
If you do not meet the minimum fundraising target your deposit will be forfeited. All sponsorship monies must be collected by 12 June 2026.
If you withdraw from the race then your deposit will be forfeited unless you agree with us (The Theatre) a suitable replacement participant who is willing to take your place, meet the fundraising commitment and pay a deposit.
