Prince Harry opens London Marathon Expo at ExCeL

The 29-year-old hairdresser said: "I am a little bit nervous about Sunday but I think the fact that I am running for a charity that has helped my family in the past is going to keep me going and get me through it".

This will be Steve's 22nd London marathon appearance, and if all goes to plan this could be his 700th sub 3hrs30mins, which will further improve his record for running 700 marathons in the fastest average finish time.

In previous years, Mr Sharp has raised money for many charities but is not doing so this year to give donors a year off.

Heads Together is the charity of the year for the 2017 Virgin Money London Marathon and brings together inspirational charity partners that have achieved great progress in raising awareness and providing vital help for people with mental health problems.

This year's marathon is designated the "Mental Health Marathon", which carries a personal connection for Frazer after suffering with his own mental health and finding solace in running.

The campaign wants people to feel comfortable with their everyday mental wellbeing, they are able to support their friends and families through hard times, and ensure fear no longer prevents people talking or getting the help they need.

The first dozen runners in the queue for their official numbers were chosen to meet the Prince and they posed behind him as he cut the ribbon.

"For me it really embarrasses the sport", said Florence Kiplagat.

One of the runners who is making his marathon debut is Stuart Richards. From Canary Wharf, the route heads west taking runners through the City of London and along the Victoria Embankment, towards Westminster and the finish line - past Buckingham Palace - at The Mall.

Roey Freilich has also been involved with Emunah for many years, and says: "I thought it was a good opportunity". I am 54. This is my 11th marathon & my link for my Just Giving Page is www.justgiving.com/justgiving/Clare-Lowery5.

She said: "I have lost two family members - Michael's uncle Tony McLoughlin and my nephew Adam Sumner to cancer in the past year".

"So because of my nephew who died, it made me more determined to get in".

Five-time Olympian Jo Pavey insists she wants to be at the World Championships to win medals - not just pick up her 2007 bronze.
