Runners from across Sussex are gearing up for one of their toughest challenges ever - and The Argus wants as many stories and pictures from the event as possible.

The London Marathon takes place on Sunday (apr 22) and people of all ages are putting the final touches to their preparations for the gruelling 26 mile event.

They will be raising thousands of pounds between them for a whole range of charities and many will be cheered on by families and friends as they pound the streets.

And The Argus wants to hear from runners after they have taken part in the marathon.

This includes stories, anecdotes and pictures.

Among the runners taking part is medical student Sarah Dwyer from Brighton. The 19-year-old is running for Cancer Research UK.

She was inspired to support the charity after her sister Katie died from a brain tumour in 2001 at the age of 11.

First time marathon runner Barry Waller, 61, from Worthing, is hoping to put a leg injury to one side and finish the race.

He said: "I have not been able to train properly for the last month so I am not going to get the time I was aiming for. It is going to take longer and it will be a bit more painful but I am determined to do it.

Barry is raising money for the Huntingdon's Disease Association.

Orthopaedic surgeon Nick Bowman from Little Horsted, near Uckfield, is raising money for the National Osteoporosis Society.

The 32-year-old, who works at the Conquest Hospital in St Leonards, said: "I am looking forward to it. I am injury free at the moment and all has gone to plan so hopefully it should all go well."

Keen runner Peter Everett, 66, from Horsham, is running for the homeless charity Shelter.
