A Hillingdon schoolboy who suffers from arthritis and a heart condition broke down barriers by beating his family in a 5K charity run.

Nine-year-old Harvey, who lives with his mum Rachael Shailes, younger sister Scarlett and older brother Taylor in Butler Street, Hillingdon, was determined to complete the run to raise money for the people who helped him at Great Ormond Street Hospital (GOSH).

The keen footballer was joined by his family, including Ms Shailes' partner Mark, at Battersea Park for the charity run.

Harvey, a pupil at Highfield Primary School, in Charville Lane West, Hillingdon, was diagnosed at the age of four with psoriatic arthritis, which is linked to the skin condition psoriasis, and is most common in middle-aged people.

He also has hypermobility and uveitis, an eye condition which causes inflammation of the uvea and a few months ago was diagnosed with aortic stenosis, a narrowing of the aortic valve in the heart, which restricts blood flow.

He was first diagnosed at GOSH and before getting weekly injections at home for his conditions he was admitted to the hospital three times a year.

"Harvey did all his stretches and was absolutely buzzing for the run," his mother said.

"It was a beautiful hot and sunny day, and the park looked amazing filled with blue Race for the Kids t-shirts. 

"The run started, and Harvey and his Brother ran off ahead – competitive as always – and agreed to meet us at the meeting point past the finish line.  Mark and myself followed them just a little  slower, along with my 4 year old daughter, Scarlett, who ran the full 5k with us, high fiving anyone she passed, and pouring water over her own head at every drink point to keep cool," she said.

Harvey finished the 5k in an impressive 30minutes, followed closely by his brother Taylor, with the rest catching up at a respectable 50 minute finish time.

A footballer for a youth team at Harefield United Football Club, Harvey had some big supporters in some slightly older players.

His grandad Kevin Moles pulled on his football boots for a charity match to add to Harvey's GOSH fund.

Proceeds from the football match, collection tins, collection buckets, and a donation from the club itself helped to raise an additional £800 to the £1000 Harvey had already raised.

Ms Shailes said: "There was a great atmosphere all afternoon, and along with the run in the morning at Battersea Park we all had a brilliant day for a great cause. 

"Harvey was absolutely shattered come the evening time, but went up to bed with a huge smile across his face.  Which was all I ever wanted right from the start."
