“1st of 2 triathlons in 2022. Great atmosphere, great route, outstanding setting. Such a good event my wife has changed from spectator to competitor for 2023. Really recommend doing it and I want to be back as a Weekend Warrior next time! “

“Blenheim Palace Tri was my first triathlon. I found it to be very well organised and an excellent day out for both athletes and spectators alike. Contains beautiful scenery and is a truly unique event, plan to do again!“
