Super-fit Doncaster man Simon Boguszewski will be attempting to set a world record in the London Marathon on Sunday, April 17.
Simon, who lives in Bawtry, will be attempting to complete the gruelling 26.2 miles around the capital with a 40lb rucksack on his back.
The present record stands at four hours 44 minutes.
He will be raising money for the Yorkshire Kidney Research Fund, of which he is vice-chairman.
Last year he claimed a world’s best when he became the fastest person ever to navigate the 13.1 miles of the Great North Run from Newcastle to South Shields with a rucksack weighing a massive 80lbs.
Simon completed the run in a remarkable two hours 54 minutes, smashing the previous best by 31 minutes.
He began competing in running events carrying a heavy rucksack to raise money for kidney research after his daughter, Jasmine, had been diagnosed with a serious condition. The load that Simon carried on his back represented her weight.
Simon said: “During 2006 Jasmine was diagnosed with acute kidney failure. Initially her prognosis was not a good one but she fought very hard and with the support of both Doncaster Children’s Hospital and Nottingham City Hospital she was extremely fortunate to make a full recovery.
“Having witnessed the effect kidney failure can have on children at first hand my wife Jemma and I are determined to do all that we can to help support medical research and development work that the Yorkshire Kidney Research Fund are undertaking in this area.”
Since he began his fundraising challenges he has raised more than £20,000 for kidney research.
