Kate Middleton Races Husband Prince William & Brother Prince Harry For Charity

Catherine, Duchess of Cambridge - commonly known as Kate Middleton to everyone, visited Queen Elizabeth Olympic Park in London on Sunday together with her husband Prince William and his brother Prince Harry.

Kate Middleton and the princes headed over to the London Marathon Community Track at the Queen Elizabeth Olympic Park in London, to support the 150 volunteers of Heads Together umbrella charity who are joining the upcoming 2017 London Marathon, reports E! News. Kate and the princes have been long supporting the charity that aimed to end disgraces about mental health.

The Royal trio competed against each other in a 50-meter (or 164 feet for those not using the English Metric System) relay race. Prince Harry took first place, William took second, and Kate came in last. The Royal couple then exchanged hugs after the race.

Kate, with her hair tied in a ponytail, wore a red puffer jacket, black skinny trousers and a matching black pair of sneakers. Her husband Prince William wore a white collared shirt under a navy sweater, olive chinos, and blue sneakers. His brother Prince Harry, on the other hand, wore a navy blue puffer jacket, matching it with dark blue chinos and olive sneakers.

"We want to normalize mental health; we want to get people talking about it, to make it more normal and to reduce the stigma. What you are doing and having so many of you here today, you've already seen the benefit of joining in," said Duke of Cambridge, Prince William, reports Mail Online. "By being a part of this marathon, we want to make it a mental health marathon," he added. 

Kate's two kids, 3-year-old Prince George & 1-year-old Princess Charlotte was not seen in the event. Kate and the princes will also not attend the 42-kilometer event to be held on April 23.
