King Frederik and Queen Mary were joined by all four of their children as they took part in the annual Royal Run event.
Crown Prince Christian, 19, ran in the 5km race in Viborg, just weeks after completing his military training, while his younger siblings participated in the one-mile family run.
Princess Isabella, 18, and 14-year-old twins, Prince Vincent and Princess Josephine, proudly posed with their medals after the race.
King Frederik kicked off the day’s events in Ribe, with Royal Run being hosted in five different cities across Denmark.
The Danish monarch founded the race in 2018 to mark his 50th birthday and it has since become an annual fixture in the royal calendar.
The monarch said of his family’s participation: “I am proud that the whole family is participating today. He [Crown Prince Christian] has completed his military service and is in the best shape he can be.
Prince Vincent, Princess Josephine and Princess Isabella were all smiles as they took part in the one-mile family run, with the teenagers all sporting the Royal Run kit.
Vincent was first to cross the finish line, and appears to have inherited his father’s enthusiasm for the sport.
Message from the siblings
The trio proudly posed with their medals after the race, writing in a joint Instagram message: “Thank you for the support for this year’s Royal Run.”
The Danish sported a pair of bright pink Nike trainers to run the 5km race and he beat his dad’s time!
Christian crossed the finish line in an impressive 21 minutes and 15 seconds, with Frederik completing his 5km in Horsens in 25 minutes and 44 seconds.
Queen Mary shared a rare glimpse inside the family’s residence, Fredensborg Castle, as she prepared to set off for her race.
The candid snap showed her making a fuss of her dogs, Grace and Coco.
“I’m on my way now,” she wrote in the Instagram caption, “Had to leave two behind that were less pleased when they weren’t going to come. I’m looking forward to experiencing the Royal Run in Korsør.”
Queen Mary took on the 5km event in the city.
