The European gold medallist has revealed that he will be taking part in a charity race at Punchestown on 28 April.
The race is in aid of the Punchestown Kidney Research Fund and Bertram is also encouraging people to sign up to the organ donor register.
“The Punchestown kidney research race is something that I’m really looking forward to,” said Bertram. “All donations would be greatly appreciated and if I could encourage you to carry a donor card also that would be great.”
The charity flat race was first held in 1990 and is staged on the final day of Punchestown Festival.
