Zara and Mike Tindall are set to miss the Royal Family's annual Easter Sunday Matins service at St George's Chapel, Windsor on Sunday, 31 March as they will instead travel to Thoresby Hall in Nottinghamshire to compete in a three-day equestrian event.
The couple, who are parents to Mia, 10, Lena, five, and Lucas, three, will not be joining King Charles as he makes his first appearance at a large-scale public event for the first time since his cancer diagnosis.
The Tindall's will not be the only family missing on the day as the Prince and Princess of Wales, Prince George, Princess Charlotte and Prince Louis are expected to spend the day at Anmer Hall in Norfolk.
It's believed Zara will compete with two horses in the Advanced competition at the Eventing Spring Carnival, which will take place from 29 March until 31 March.
Her father Captain Mark Phillips is returning for a second year as course advisor alongside BEDE Events' Stuart Buntine.
"They have a nice easy start and then the middle of the course, around the house, is quite serious, and then when they’re back across the road it’s a nice way to finish," Captain Mark Phillips said.
"It's a special place, Thoresby, the know the ground here can be excellent and that's what we hope for, and we've ordered a nice sunny day – but the sun on the riders backs and a smile on their face."
Buckingham Palace recently announced that King Charles and Queen Camilla will be joining other members of the family for the service - however they will be sitting separately to protect the monarch's health.
This will be the 75 year old monarch's first public engagement since he was diagnosed with cancer, after it was reported that he is very keen to get back to work and make appearances at key royal events in the summer.
While the King will be present, the Wales family will not as they are expected to spend the day at Anmer Hall in Norfolk following the announcement that the Princess of Wales is also undergoing treatment for cancer.
The home, which was given to the couple by Queen Elizabeth II after their wedding in 2011, is thought to be their favourite residence to escape to - and is somewhere where they have a wide circle of close friends.
Significant renovations were completed a number of years ago - including a new roof, a conservatory, new kitchen and several trees were planted to give the Prince and Princess more privacy. The refurbishments cost £1.5 million and was paid for using private Royal Family funds.
The family also lived in Norfolk all the time between 2015 and 2017 because Prince George was going to nursery nearby at the Westacre Montessori School.
