Who do you think won in a race between Kate Middleton, Prince William, and Prince Harry? The three royals were in London on Sunday to support the runners training for the upcoming London Marathon as part of the Heads Together program, which is spearheaded by the royal family and aims to change the conversation about mental health. While they were at the track, the group decided to have a friendly competition to see who was the fastest. The Duke and Duchess of Cambridge faced off against each other and Prince Harry in a 100-meter dash, much to the delight of the event's attendees.
