Tindall, then known by her maiden name Phillips, was part of the group that won silver at London 2012 in the team eventing competition. 

Her mother, Princess Anne, an International Olympic Committee Member, presented her medal.

She was then unsuccessful in her attempt to qualify for Rio 2016 and did not try for the postponed Tokyo 2020 edition of the Games.

Tindall is back in training but owns fewer horses than in 2012 and has to fit her practice sessions around being a mother of three.

She says having horses in stables at home makes things easier.

"When you finish around here you definitely know if you've got a good horse, a good combination," Tindall told Vogue.

"So it is one of the best events in the world where you can really find out where you're at in your training and the horse's future."

The 41-year-old is also hoping to compete in the Magic Millions showjumping event in 2023 and 2024 before the Olympic Games.

She qualified for both Athens 2004 and Beijing 2008, but an injury to her horse forced her to withdraw from the team on each occasion.

Tindall followed in her parents footsteps, with Princess Anne competing in the Montreal 1976 Summer Olympic Games in eventing and also winning individual gold at the Burghley 1971 European Championships.

Her father Mark Phillips won team eventing gold with Britain at Munich 1972 and then silver in the discipline at Seoul 1988.
