The Blenheim Palace Triathlon returned for its 20th edition at the weekend with more than 6,000 people taking part.
The triathlon took place on June 1 and 2 in Woodstock, and saw an increase in entries from last year.
One notable participant was British professional marathon runner, Anya Culling, who recently completed the Wizz Air Hackney Half.
The Blenheim Palace Triathlon is thought to be the only triathlon in the world which takes place in the grounds of a UNESCO World Heritage site and it is one of the most-popular mass participation triathlons in Europe.
The triathlon caters to beginners with an accessible route, making it a favourite among newcomers to the sport.
Participants had the choice between a sprint distance consisting of a 750m swim, 19.8km bike ride, and a 5.4km run, or a super sprint distance consisting of a 400m swim, 13.3km bike ride and a 2.9km run.
All finishers received a medal, t-shirt and Blenheim Palace Triathlon swim hat for completing the event.
For more advanced athletes, the Weekend Warrior option allowed participants to push their limits by completing as many back-to-back triathlons as possible over the two days.
Four participants managed to complete the sprint distance eight times over the two days.
A host of clubs from across the country brought triathletes in their numbers to the event, including more than 100 triathletes from London-based Kensal Tri, Army Triathlon Association, and female participation charity Fund Her Tri.
There were also a number of regional clubs from Oxfordshire including Oxford Triathlon Club, Bicester Triathlon Club and Abingdon & Vale Triathlon Club.
Race director Andy Taylor said: "It’s been an incredible weekend here in Oxfordshire, the Blenheim Palace Triathlon delivered once again.
"All participants got to enjoy the incredible scenery and the variety of race distances makes it a really inclusive event."
He added: "We’re honoured to have organised the 20th edition of this iconic event and seeing the effort put in by the triathletes, staff, partners and volunteers is inspiring, congratulations to all involved.
"We’ve also raised a brilliant amount of money for charity and it’s wonderful to hear all the stories of individual fundraising successes from the weekend."
The 2023 event saw nearly 5,000 people take part including household names such as BBC Radio 2 presenter Jo Whiley.
Motiv Sports UK, which hosted the event, will also host the Oxford Half later this year on October 13. The event has already sold out in record time.
Entries for the 2025 Blenheim Place Triathlon are already open on the triathlon's website.
