Princess Kate and Prince William have a competitive side, so they didn't mind getting a chance to settle it on the track.
As part of their Heads Together campaign, the royal couple joined Prince Harry at the London Marathon Community Track to take part in a relay.
They participated in the first leg of a relay, each one running 50 meters. Harry beat his brother with Kate coming in third, but not by much.
“You nearly beat me!” William playfully told Kate at the finish line, PEOPLE reports.
The trio often participates in events to raise awareness for mental health. They were at the race on Sunday to chat with those training for the London marathon to raise money for the Heads Together team.
