Prince William and Kate, the Duke and Duchess of Cambridge, took a trip down memory lane Wednesday, visiting the university in Scotland where they met.
The parents of three, who recently celebrated their 10th wedding anniversary, also embarked on an adventure, racing against each other in land yachting.
William and Kate, known for their competitiveness, took off on the land yachts on the famous West Sands beach at St. Andrews.
The helmet-clad couple was joined by caregivers who took part in the sport through Fife Young Carers, an organization that helps local caregivers "maintain their physical and mental wellbeing through a range of outdoor activities, workshops and residential trips," according to Kensington Palace.
In addition to racing alongside them, William and Kate spoke with the caregivers about the difficulties they have faced during the coronavirus pandemic, according to the palace.
After the land yachting, William and Kate, who are on a week-long tour of Scotland, visited St. Andrews University, where they first met and fell in love as students 20 years ago.
Their return to the university saw the Cambridges talking with students about how they have coped during the past year-and-a-half of the pandemic, joining an interfaith discussion on support during the pandemic and learning about an initiative to help students' mental health.
William and Kate also planted the first tree for the St. Andrews Forest, which is designed to help the university become carbon neutral by 2035, according to Kensington Palace.
During their days as students at St. Andrews in the early 2000s, William and Kate started out as friends and later became roommates.

Jules Knight, a classmate of the couple, shared memories of the two in a BBC America special that aired after their engagement in 2010. He said William seemed smitten with Kate from the beginning.
"I think he, he just took a shine to her, really," Knight said. They "spent a lot of time together and were very good friends for a long time, and I think that blossomed into something more."
