The Olympic Stadium will host the start of many an ambition for athletes this summer, but for one runner it marks the end of a remarkable 310-mile journey.

Gap-year student Arthur Gallimore, 18, spent his Easter break travelling from Land’s End – via Cornwall, Devon, and Hampshire – on foot and is due to finish up at the Stratford arena tomorrow.

Charity-funded trips to eastern Europe last year inspired him to run 12 marathons in 20 days in aid of deprived children in Romania.

His aim is to raise �5,000 for the charity LimXpo, and he is more than one third of the way there.

He said: “After my second visit to the projects last summer I came back and wanted to do something to raise money for the charity.

“The work they do is amazing, the effort I am putting into this challenge is nothing when you look at all the time and effort that the charity workers will be putting in.”.

Arthur, from north London, will study medicine at Keele University later this year, with the ambition of becoming a doctor.

He has been backed by family and friends.

His father Simon, who once worked at the Carpenters Estate for the Media Trust charity, has been following him from the comfort of his car.

Mr Gallimore said: “He wanted to finish at the Olympic Stadium because of the Games this summer. Land’s End is a usual place to start but we thought John O’Groats would be a bit too far.

“As a man of considerable will and determination, when he sets his mind to something he usually does it.”
