The brother of Katherine Kendall is planning to run a marathon to raise money for his sister to have life-changing neurosurgery. He is appealing to Star readers to help by collecting sponsorship pledges from friends, neighbours and workmates.

Oliver Kendall (22) said he has never run a marathon before, but is determined to do anything he can to help Katherine (18). He is very fit, having captained the Manchester University Athletics team last year and has been training on roads around the family home in Frimley Green.

He sees the pioneering operation, available only in America, as his sister's only chance for a cure for her severe epilepsy.

His gruelling 26 mile run will start and finish outside the Star office in Victoria Road, Aldershot,at 12 noon on Sunday, May 5, and he is not trying to set any records, but is fairly confident that he can finish the course.

His route will take him through Ash, North Camp, Mytchett, Frimley, Camberley and back through Farnborough to Aldershot.

Meanwhile Katherine's mum Anna has been collecting door to door, along with some family friends, and they have had a tremendous response from sympathetic residents. Other friends have taken up collections at their workplaces and the fund is gathering pace, but the family still has about £125,000 to raise.

Any reader who would like to make a donation or help by collecting in their road or workplace for the Katherine Appeal charity can contact the family on 01252 836880 or log on to www.katherineappeal.com or write to them at 10 Chartwell, Frimley Green, Surrey, GU16 6HW.
