King Charles Continues Busy Royal Week with Trophy Awarding Duties at Royal Ascot

Queen Camilla, Princess Anne and more royals joined the King at the horse racing event's first day, arriving in carriages as part of the Royal Procession

King Charles and Queen Camilla's busy calendar is continuing with Royal Ascot!

After attending Trooping the Colour on Saturday and Garter Day on Monday, the royal couple attended the first day of the horse racing event at the Ascot Racecourse on June 18. They led the way in the Royal Procession, which typically marks the start of every race day. Four horse-drawn carriages entered the racecourse at precisely 2 p.m. local time to kick off the event.

King Charles, 75, looked dapper in a suit and top hat, following the event's strict dress code requirements for the Royal Enclosure. Men are asked to sport morning dress (in black, grey or navy only) with a waistcoat and necktie ("patterns of a patriotic nature, for example a national flag, are acceptable," the dress code states). Black or grey top hats are required but can be removed when inside a restaurant, private box or seating areas. Socks must cover the ankle.

Queen Camilla, 76, sported a blue ensemble by one of her go-to designers Fiona Clare with a coordinating hat.

King Charles and Queen Camilla rode with the Duke and Duchess of Wellington. Traveling in the second carriage were Princess Anne, Peter Phillips, royal racing manager John Warren and Lady Gabriella Kingston (in her second appearance with the royals since the death of her husband, Thomas Kingston).

Queen Camilla's sister Annabel Elliot and her nephew Ben Elliot took part in the Royal Procession as well, riding in the third coach.

Although they didn't take part in the Royal Procession, Zara and Mike Tindall were also spotted at the first day of Royal Ascot. King Charles' niece, who won a silver medal in an equestrian event at the 2012 Olympics in London, is a regular at horse racing events.

Princess Eugenie was also spotted at the event.

Queen Elizabeth was a great supporter of the equestrian event, and 24 of her racehorses won at Royal Ascot through the years. Her heir has continued the tradition, and one of the races taking place on June 18 was renamed the King Charles III Stakes. The King is expected to hand out the trophy to the winner of the race.

Meanwhile, Queen Camilla will present the award for the St. James's Palace Stakes, and Princess Anne will congratulate the winner of the Conventry Stakes.

King Charles recently resumed public outings amid his cancer treatment. After spending months working mainly behind the scenes or taking part in small audiences, the King quipped during a May 9 outing to the Royal School of Military Engineering that he was glad to be "out of my cage."

He was honored on June 15 at Trooping the Colour, the British Army's annual celebration of the British monarch's birthday in London. Instead of riding on horseback as he did in previous years, King Charles took part in the procession through the city seated in a horse-drawn carriage alongside Queen Camilla.

Two days later, King Charles joined members of the royal family at Windsor Castle for Garter Day. The Order of the Garter ceremony has been held annually since 1948, celebrating the oldest and most senior order of chivalry in the U.K. King Charles, Queen Camilla, Prince William and more took part in the Garter Day procession wearing ceremonial garb: the order's blue velvet robes and hats topped with a white ostrich feather.

Later this month, King Charles and Queen Camilla will host the Emperor and Empress of Japan during their state visit to the U.K.
