Prince Harry, William, and the duchess of Cambridge, Kate, raced into a 50-meter sprint against each other on Sunday at London's Queen Elizabeth Olympic Park. It was one of their ways to promote mental health campaign which was called Heads Together.

The royalties were cheered by track stars and as well as amateur runners who trained for the April's London Marathon. Harry was able to cross the line and stride ahead of his older brother, Prince William. During the race, Prince William and wife Kate hugged at the finish line, CTV News reported.

On the other hand, Prince William was perhaps aware that his brother would beat him. Harry was considered as more athletic than him and even had equipped moments before the start of the race. One of their spectators who was a marathon world record holder, Paula Radcliffe said jokingly that Prince William should had been disqualified for staying into Kate's lane.

The royal trio had raced with each other which lead the first-leg of the five person relay, alongside joggers on the lane as well. Prince William was seen enjoying the rivalry between his brother and wife, and even joked at the starting line while saying, "Oh my hamstring" before he loss to Harry after a few seconds, ABC News reported.

Further, Prince Harry who is no stranger with the track also challenged Usain Bolt in his native Jamaica and showed the crowd why he was the favorite win during that day. The main purpose of the race was particularly to train runners and to promote the charity that was set up by William, Kate and Harry.

It is an umbrella organization of eight charities which were devoted to breaking the stigma surrounding mental health and to encourage all young people to join, open up and ask for help. The 150 runners who joined the race will be raising funds for one of the eight Heads Together Charity partners.
