Olympic medallist Jane Holderness-Roddam is set to return to eventing for charity.
Jane, who is now 67 years old, will compete in her first one-day event for 13 years on former four-star eventer Tiger’s Eye II.
They will be competing in the BE100open.
Jane was the first woman to represent Great Britain in eventing at Olympic level and won team gold in Mexico in 1968.
She also won Badminton twice, in 1968 and 1978, and Burghley in 1976.
Tiger’s Eye II, known as Bill, is a 20-year-old gelding with 310 British Eventing points.
By Java Tiger, he has competed at 30 international events, including four CCI4*s.
“Horses have been a part of my life since childhood, and caring for them properly is really important to me,” said Jane.
“Bill is still able to compete at the age of 20 in part because of the excellent care he has had from a dedicated team.
“Sadly, some equine animals working around the world are lucky to reach a quarter of his age. I want to help change that.”
Jane is a trustee for both World Horse Welfare and the Brooke.
In 2014, she travelled to Senegal to see the Brooke teams at work.
Petra Ingram, the charity’s chief executive, said: “We are so incredibly grateful that she has decided to go the extra mile, or should I say extra jump, for the Brooke and World Horse Welfare.
“The money raised will help us reach our target of helping two million horses, donkeys and mules by 2016.”
World Horse Welfare chief executive Roly Owers added that Jane had played a “pivotal role” in the charity’s work.
“I wish her the very best of luck with the event and I, along with all at World Horse Welfare, will be cheering her on,” he said.
