Zara Tindall gets back in the saddle to compete on day one of The Burnham Market International Horse Trials

Zara Tindall was back in the saddle today as she competed at The Burnham Market International Horse Trials in Norfolk.

Teaming a chic navy double-breasted jacket with white jodhpurs, the daughter of the Princess Royal, 42, looked like she meant business as she elegantly drove across the impressive course.

The King’s niece, who shares daughters Mia, ten, and Lena, five, and son Lucas, three, with former England rugby star Mike Tindall, also donned a navy and white riding cap.

Beaming Zara looked to be enjoying the action as she dominated the track on day one of the event.

Her outing comes after it was revealed her brother Peter Phillips, 46, has split from ‘rock solid’ girlfriend Lindsay Wallace after three years together.

Zara’s illustrious riding career includes a gold at the European Championships in 2005 and a silver at the World Equestrian Games in 2006.

Last month, the royals kicked off the Easter weekend with an equestrian competition and joined the cream of British eventers at the Thoresby Park International Eventing Spring Carnival in Newark.

The Princess Royal’s daughter looked relaxed during the first international event of the British season, which is seen as a precursor to the Badminton Horse Trials in early May.

Wearing bright white jodhpurs and a navy jacket over a gray hoodie, with a navy and white riding hat, the royal also donned sunglasses as she put her beloved gelding Class Affair through his paces at the event.

Meanwhile, Zara’s brother Peter, who is said to be the late Queen’s favorite grandson, began dating his old friend Lindsay, 43, following his divorce from Autumn Kelly, 45, in 2021.

The couple have now gone their separate ways after the relationship ‘ran its course’, a source said the sun.

Peter and Lindsay, the daughter of an oil tycoon, are still friendly and no one else is believed to be involved.

Lindsay has attended various royal events with Peter, who is very close to his uncle King Charles.

‘They were friends before their relationship blossomed. But Peter and Lindsay have gone their separate ways as the relationship simply ran its course, says a source to the Sun.

A friend of the couple added Hello! that Peter’s work commitments mean that he has been traveling ‘non-stop’.

‘Peter and Lindsay made the difficult decision to separate as they spent less time together with work and family commitments. Peter’s business commitments and work in F1 meant he has been away traveling non-stop,” the source said.

‘Obviously it came as a shock as most people thought they were rock solid, it’s very sad. Peter has been traveling all over the world and has been incredibly busy and Lindsay is based in Scotland so it has been difficult for them to see each other.’

The late Queen’s grandson, who lives at his mother’s Gatcombe Park estate, does not receive money from the royal grant and works as head of partner acquisitions for rights agency CSM Sport & Entertainment and as an ambassador for ISPS Handa, as well as various other endorsement gigs.

In June, a friend of the king’s nephew told Hello that Peter has always been ‘extremely close’ with Charles and that ‘it meant a lot’ that he was able to take Lindsay to the Coronation concert.

The source told the show: ‘He’s in a great place at the moment and couldn’t be happier in either his private or personal life.’

The friend added that the pair look ‘so natural’ in each other’s company, adding that they are ‘incredibly happy’ together.

“Lindsay is truly a breath of fresh air and it’s clear to see that both Lindsay and Peter love life,” the friend continued.

Peter and Canadian-born Autumn announced their separation in 2020, with the divorce finalized in 2021. They share two daughters, Savannah, 13, and Isla, 12.

Meanwhile, stay-at-home mum Lindsay split from businessman of 11 years, Andrew, around the same time Peter announced his divorce.

Mum-of-two Lindsay knows Peter and his sister, Zara, from their school days in £45,000-a-year Gordonstoun.

Lindsay was in the same year as Zara at school and was among the guests at the royal wedding in 2011 to rugby star Mike.

Rumors of a romance between Peter and Lindsay first surfaced when he visited her in March 2021 – raising questions about whether he had breached lockdown restrictions.

Eight months later, he showed he was serious about his new relationship when he brought Lindsay as his date to his nephew Lucas’ christening. The pair were photographed in a car together ahead of the gathering.

Peter, the eldest child of Princess Anne and her first husband, Captain Mark Phillips, then took the very momentous step of introducing Lindsay to her late grandmother, Queen Elizabeth II, who is said to have been “delighted”.

Lindsay was introduced to her late majesty at a shooting party in Windsor and the meeting was described as ‘warm’ by a source.

A spokesman for Peter confirmed at the time that Lindsay had accompanied him to the joint christening of Zara and Mike Tindall’s son, Lucas, and Princess Eugenie and Jack Brooksbank’s son, August, in Windsor.
