Sandringham, UK - Prince William had a busy couple of days as he celebrated Father's Day and his birthday back to back, all while hosting a charity race with his children George and Charlotte.

The Duke and Duchess of Cambridge have had a busy spring, from getting vaccinated, participating in countless charity initiatives, to a bit of race-car driving.

Instead of a lazy day at home with breakfast in bed for Father's Day, the Duke of Cambridge took two of his three children to Queen Elizabeth's Sandringham Estate to host a charity half-marathon.

It was a sunny, crisp day - and by all accounts it seems the children had a blast.

The team of three worked together on stage to announce the start of the half-marathon with the microphone and to cheer the participants on. The good times then continued as he celebrated his 39th birthday right after Father's Day.

He received sweet tributes from his father, Prince Charles, his grandmother, Queen Elizabeth, and countless fans on social media.

As People reported, William's relationship with his brother, Prince Harry (36) could soon be on the mend as well. In the coming weeks, the two will unveil a new statue at Kensington Palace dedicated to their late mother, Princess Diana.
