During a training event for the London Marathon at the Queen Elizabeth Olympic Park, Middleton had some fun during a relay race against her husband, Prince William, and brother-in-law Prince Harry.
The three lined up and sprinted down the track toward their relay partners. The Duchess of Cambridge gave an impressive effort in a pair of New Balance sneakers and a sporty red jacket by Perfect Moment.
The event was held by Heads Together, which is a charity started by the Duke and Duchess of Cambridge and Prince Harry supporting mental health causes. The charity is also the London Marathon’s Charity of the Year.
Today, Middleton was back in her usual attire — a favored Luisa Spagnoli suit and Gianvito Rossi pumps — for an event at Place2Be, a children’s mental health charity that is part of Heads Together. The event marks the start of Children’s Mental Health Week.
