Supermarket boss Jinx Hundal has completed a double marathon challenge for a cancer charity close to his heart - and is now looking for a worthy cause to support with a hat-trick of runs planned next year.

The 35-year-old who owns Budgens at Cromer was inspired to tackle the marathons by the courage of staff member Shirley Lodge who died this summer, aged 52, from the breast cancer she thought she had beaten a decade ago but which returned and spread.

In October he did his first ever run, in Amsterdam, clocking a time of 4hr 59min, and has now done another in Dublin, in 4hr 14min.

'I have really got the bug, and I think I have more fuel in the tank,' said Mr Hundal, who has now applied to do the London marathon for the NSPCC charity next spring.

'I would like to get under four hours, and am hoping to do three marathons in three weekends next year - and find a good cause to run for,' he added.

Mr Hundal thinks his two runs have raised �2,000 for Cancer Research UK and Norfolk cancer charity Big C.

'I have kept fit through hiking, but never put my poor little knees through a marathon. They really hurt and my legs were like lead towards the end - but my last 5k was the quickest - helped by the big crowds.'

Mr Hundal, who also runs stores at Norwich and Brundall, added: 'I did a really steady pace in Amsterdam, helped by a GPS device, but set it quicker in Dublin, and think I could beat four hours. I think Shirley would be really proud of me.'

Anyone with a charity for Jinx to support should drop ideas into the Cromer store or e-mail him at jinxhundal@gmail.com

? Cromer Hospital manager Helen Lloyd also did the Dublin run and has raised about �390 for the Cots for Tots appeal at the Norfolk and Norwich University Hospital.

She did the course in 4hr 7min, three minutes quicker than the London marathon this year.

The regular marathon runner, who lives at Marham, said: 'The course and crowds were great and the weather overcast, drizzly but warm until the last 200 metres when the rain poured down!'
