Their Royal Highnesses met some of the 700 runners taking part for Heads Together, the campaign they lead which is the Marathon’s Charity of the Year, before officially starting the mass race.

Thousands of runners wore the blue Heads Together headbands given to runners to show their support for the ‘mental health marathon’ and help get the country talking and start a new movement for mental health.

The Duke and Duchess of Cambridge and Prince Harry cheered on runners and met friends and family of Team Heads Together as well as handing out water to thirsty runners at Mile 22 and placing medals over their heads after the finish line.

The mental health marathon is a culmination of a year of campaigning to change the conversation on mental health. This has included a series of films featuring people from all walks of life talking about their mental health. Model Adwoa Aboah and London blogger Jo Irwin, who took part in the #oktosay film series, both cheered on Heads Together runners at the marathon.

The Duke and Duchess and Prince Harry are thrilled that so many runners have chosen to wear Team Heads Together headbands today. Regardless of the great causes they are running for, thousands of people have put on a headband to make this the Mental Health Marathon.
