The best friend of a Birmingham surveyor who was stabbed to death is to run the London Marathon in his honour.

Guy Moreve turned to running to cope with the grief of losing Paul Tanner. The pair grew up together and shared a flat in the city centre when Paul was murdered in a robbery.

Now Guy, aged 25, is to run the marathon in Paul's memory and to raise cash for Marie Curie Cancer Care.

Guy, a marketing executive with Yellow Pages, said: "Paul was a great friend - we'd known each other since we were four; the flat felt empty without him. That is what drove me to go running.

"While I was running it gave me chance to think about things and I could take all of my frustrations out on the road itself. It was initially a cathartic process for me.

"But what started as way of getting out of the flat soon turned into a quest to do something positive."

Paul, aged 23, was walking through St Paul's Cathedral, in the Jewellery Quarter, to his nearby home when he was confronted by three robbers. Antwya Bennett (17), from Newtown, forced Paul to hand over his wallet containing £40 but still plunged a knife into his chest. He was jailed for life last year. Guy has raised almost £5,000.
