As I’m watching a child blasting a horn (not sure if it's a real one) to the tune of military music, a crowd suddenly rushes towards me - or so I think - but they simply dash past.
Then it clicks. They’re chasing after the royal carriage. The King has just swept by in front of them.
Members of the Royal Family are centrestage as they celebrate the King's official birthday.
The King and Queen are travelling in an Ascot Landau carriage, which was purchased during the reign of Queen Victoria.
Meanwhile, Prince William is on a horse called Darby, while Princess Anne is on Noble, and Prince Edward on Sir John as they make their way back along The Mall.
The Princess of Wales and her three children are travelling in an open carriage, smiling and waving to crowds along the procession route.

It has been a turbulent year for the Royal Family.
Since the last Trooping the Colour, we have seen the scandal around the King's brother Andrew Mountbatten-Windsor widen and more questions being asked around royal properties and finances.
But today is very much the traditional display of royalty - showcasing pomp and ceremony and the role of the King as head of the armed forces.

Some protesters are holding bright yellow placards reading "Not My King" - and that's also what they're chanting.
When the troops pass by, they seem to shout louder.
They're also holding up photos of Andrew Mountbatten-Windsor, the King's brother, who was stripped of his royal titles over his connections to convicted sex offender Jeffrey Epstein.

Image source, Getty ImagesThe anti-monarchy group, Republic, is protesting at Trooping the Colour today as it has in previous years.
The group says it is a public event and it has every right to peacefully protest in front of Buckingham Palace.
The Metropolitan Police say they have a policing plan in place to ensure Trooping the Colour passes off safely and peacefully, including minimising disturbance to horses taking part.
And the police also say they are "working with protesters to ensure we can balance these needs with their right to lawfully protest”.
The King and Queen are now leading a procession back up The Mall to Buckingham Palace, where a further salute will take place.
Then at 13:00 BST, members of the Royal Family will watch the Red Arrows flypast from the balcony at the palace.

There is some sadness today too.
Lance Bombardier Ciara Sullivan should have been riding this year at Trooping the Colour, but she died after falling from her horse during the Royal Windsor Horse Show in May.
In recent weeks, soldiers of the King’s Troop Royal Horse Artillery have paid tribute to her during a number of events and preparations for today.

We've seen the foot guards parade, now it's the turn of the mounted troops.
Pictured above are the King's Troop Royal Horse artillery.
Then come the Mounted Band of the Household Cavalry.

To his right is Queen Camilla, and the Princess of Wales sits to his left.
As the future Queen, she gets a prime seat - especially now that she is well enough to attend after her cancer treatment.
And, as an honorary colonel of the Irish Guards, she has a military interest in the parade.
Friends Emma McCarthy, from Swindon, and Sarah Fuller, from New Malden, are watching Trooping the Colour on The Mall.
Emma says the spectacle is one of her favourite days of the year.
"It is a day to celebrate our wonderful Royal Family, and the highlight is seeing the Wales children on the balcony.
"We come every year and stand in the same spot."

Image source, ReutersThe Trooping the Colour ceremony is in full swing at Horse Guards Parade, with the King and prime minister among those watching on.
The bands have been on full display, carefully keeping formation as they change direction, all while simultaneously playing their drums and horns.
A slow march has also been taking place across the square as the colour is handed over to an escort, who then parades it through the ranks.
Some of the guards have been standing still for 51 minutes as the ceremony takes place.

The colour, or flag, of the Grenadier Guards regiment is being trooped (carried) through the ranks of foot guards.
Next, the foot guards will march past the King followed by The King’s Troop Royal Horse Artillery and the Sovereign’s Escort of the Household Cavalry.
The King will then lead his guards back to Buckingham Palace, where a further salute will take place before the troops return to barracks.
Eight-year-old Sophie Moore, from Letchworth, won a ballot to represent Hertfordshire Brownies at Trooping the Colour today.
Proud dad Aidan says: "She's so excited to be seeing the King and Royal Family.
"It's her first experience of marching bands and she is loving the ceremony.
"If she could meet the King she plans to ask him what kings have for breakfast."

"Gosh there are so many horses!" one woman exclaims to her children next to me.
As troops and horse-riders march from Buckingham Palace, the public cheers and waves to them.
Many others simply stay silent and film the action.
The real winners are those who came prepared, bringing their own stools to stand on.
"You're not recording," a woman tells a child perched on a man's shoulders.
The screen of his phone still has a red circle instead of a square.
The child tries to flip his phone - and it promptly falls on the man's head.
The King has been greeted by a royal salute at Horseguards Parade.
He is now inspecting the troops.
Then the Trooping the Colour parade will get under way.

Second Lieutenant in the Grenadier Guards, Alec Goschen, has been chosen as The Ensign today - the solider who will carry the colour (the flag) of the Grenadier Guards.
He is 6ft 7in tall but reaches 8ft 6in when wearing his bearskin.
He is easy to spot, towering over his fellow soldiers.

Crowds are being treated to the sight of a royal carriage procession along The Mall.
The King, Queen and the Princess of Wales, who is joined by her children, are guarded by a Sovereign’s Escort provided by the Household Cavalry Mounted Regiment.
But the Prince of Wales is not sitting in the carriage with his family.
Instead, Prince William is riding in the formation of royal colonels alongside his aunt and uncle - Princess Anne, the Princess Royal, and her brother Prince Edward, the Duke of Edinburgh.
Prince William is travelling on a horse called Darby, Princess Anne is on Noble, and Prince Edward is on Sir John.

They are travelling in an Ascot Landau carriage, which was purchased during the reign of Queen Victoria.
The King is wearing the uniform of the Grenadier Guards, which is the regiment trooping the colour today. His uniform features the cypher of Queen Elizabeth II as he was personal aide-de-camp to his mother - the honorary position is only held by members of the Royal Family with military rank.
The King is also wearing a number of medals - ranging from Queen Elizabeth II's Coronation Medal (1953) to the Platinum Jubilee Medal (2022).
Queen Camilla is wearing a red, silk crepe, grenadier guards uniform dress designed by Fiona Clarke, along with a black beret featuring a white plume and Grenadier Guards cap badge designed by Phillip Treacy, and a grenadier guards brooch.
