Inspired by his father's prostate scares, a 40-year-old will take on a marathon challenge with a niggling ankle injury to raise awareness for urology.

Not only is running 26 miles a personal goal, the effort is all in aid of a charity close to the heart of Tony Norris, of the Drive, Esher.

His father, Steven, 69, has had a few prostate scares scares in the past five years, so Mr Norris, a lawyer, is running for the Urology Foundation.

Mr Norris, who is married to Suzanne, and has two children, Ollie, five, and Hugo, three, said: "I've always wanted to run a marathon but I'd never got round to doing it or even a 10km run."

In the week before the race, Mr Norris said: "I'm a little bit nervous, I'm actually carrying my ankle injury still."

More than £2,000 has been donated and Mr Norris hopes complete the race in under four hours.

He said: "Urology isn't something you think about until you are personally affected. My dad had a couple of prostate scares and it is concerning when there is something wrong with someone you love and care about."

He has been training since June and will run alongside his wife, who will be running the half marathon distance, on Sunday, October 19.
