They may be royal and next in line to the throne but Prince Harry and brother William proved they weren't above getting stuck in this afternoon.
The duo donned their polo gear to take part in a charity match at Cirencester Park Polo Club in Gloucestershire.
And the activities appeared to tire out the flame-haired prince, who was photographed guzzling on a bottle of water after the event, reports the Daily Mail.
But ultimately it was his brother who looked the most exhausted - putting his palm to his face at the end of the match.
The brothers, who share a close bond, were participating in the Jerudong Trophy in a bid to raise funds for their chosen charities.
Billed as an intimate day by the event organisers, tickets started at £15 and offered punters the opportunity to watch the royals play in the horse-born sport.
The ticket price included access to the clubhouse restaurant and Tea Room and grandstand seating.
This year the annual event was held to raise awareness and funds for for The Household Cavalry Operational Casualties Fund, and two charities that The Duke and Prince Harry support as Patrons: Centrepoint, whose Patron is The Duke of Cambridge, and Walking with the Wounded, whose expeditions Prince Harry has been Patron of for a number of years.
And this game is just one in a series of charitable matches lined up for the royal princes this summer.
The Duke and Prince Harry have both been playing polo in support of their charities for a decade, and have raised over £10 million for charitable causes to date.
A love of all things equestrian runs in the family, with several members having played for Great Britain at international level.
Their aunt Princess Anne and cousin Zara have both competed at the Olympics in eventing, with Zara earning a silver medal with the British team; both are winners of the annual Sports Personality of the Year award.
Their love for the sport is thought to have come from their father Prince Charles. Both he and Prince Philip were keen players and often competed in tournaments.
The match today comes after a busy week for the pair who have attended war memorial events across the country.
But it hasn't been all work and no play as Prince Harry took time to meet veterans and stars of Hollywood on Thursday evening for the latest Christopher Nolan blockbuster Dunkirk premiere at the Odeon in Leicester Square.
The prince, a former army officer himself, quizzed survivors - now in their late 90s - about their experiences.
Harry learned first hand about the massive 1940 operation to save hundreds of thousands of servicemen from advancing Nazi forces when he met men who had been on the French beaches.
Prince Harry last played at Cirencester in 2015. The keen equestrian got heated as he galloped across the field and shouted at teammates.
