AN intrepid mum has completed a gruelling 100 mile race inspired, by her nephew who has an incurable kidney condition.

Mum-of-two Shirley Anderson beat her nearest female competitor in the Grim Reaper Ultra Marathon at Grimsthorpe Castle in Lincolnshire, by an incredible three hours.

Shirley, aged 45, of Sandymoor, who works for Persimmon Homes, said: “The race went very well overall, however it was painful at times.

“You go through so many emotions when you’re running massive distances and this was no different.

“When I was running through the night I thought about how pleased I would be to finish and that I wouldn’t be running a 100 mile race again.

“However when the sun starts to come up you get an extra lease of life and it really picks you up. I even managed to find a sprint finish.”

The rules state that the race must be completed within 26 hours, but Shirley finished it in 21 hours 38 minutes, beating her own target by 22 minutes.

Shirley added: “Upon finishing I was elated and I am already starting to think ahead to my next 100 mile ultra marathon and achieving a faster time.”

Shirley, who has two teenage children, was running for Kidney Research as her 12-year-old nephew, Harry, has a rare condition affecting his kidneys.

Shirley has raised almost £900 so far. Over the years, she has donated around £9,000 to various charities including Marie Curie, Macmillan Cancer Support and Get Kids Going.
