After a day of running around Denmark—literally, as Monday was the annual Royal Run—the Danish Royal Family shared a snap of their surprising family tradition: spaghetti Bolognese.

“Traditionally, dinner with us is spaghetti Bolognese after the Royal Run,” King Frederik and Queen Mary shared on their social media accounts. “Thank you for this year – see you next year.”

The Royal Run, created as a 50^th birthday initiative for then-Crown Prince Frederik in 2018, is a registered run throughout the Danish kingdom. Each member of the Danish Royal Family heads to a different part of the country to run with the locals.

King Frederik began his day in Ribe, in the southwestern part of the country, sharing a selfie from a sailboat as he revealed that more than 97,500 runners had signed up for the Royal Run this year. “We’ve been looking forward to lacing up our running shoes again,” he wrote. “Soon the starting shot sounds…I’m looking forward to starting the day here in Ribe!”

The King also joined in a run in Horsens later in the afternoon, but was first treated to an open-air choir singing The Beatles’ classic “With a Little Help From My Friends.”

Queen Mary, meanwhile, ran in Korsør, in the Slagelse municipality where her eldest son completed his military training mere weeks ago. She shared a snap of herself petting her dogs goodbye as she headed out, captioning it: “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.”

Crown Prince Christian, now on a summer leave before he returns to Slagelse for lieutenancy training, shared a picture of himself from the backseat of a car on his way to Viborg in the heart of the country. His personal message read: “So I’m almost in Viborg, and I’m looking forward to running 5km with all the other happy and healthy runners.”

Princess Isabella, Prince Vincent, and Princess Josephine all ran in Copenhagen and Frederiksberg, sharing a group photo after receiving their medals for the One Mile race, and thanking everyone for participating. Later in the day, Princess Josephine signed off on her first Instagram post after she decided to run a second time, writing: “I also just took a 5.”

To end their race day, King Frederik, Crown Prince Christian, Prince Vincent and Princess Josephine all took part in a 10km run in Copenhagen. After his younger sister crossed the finish line, Prince Vincent told reporters how proud he was.

“I think it’s really cool that she’s taking all three races, I’m proud,” Prince Vincent said of his twin.
