Former Southampton and England footballer Danny Wallace is approaching the end of his London Marathon effort in aid of multiple sclerosis (MS) sufferers.
Wallace, 42, who was diagnosed with the disease in 1996, is finishing the last miles of the 26.2-mile course today.
Only able to walk and prone to considerable fatigue, Wallace is determined to finish to ensure that his charity, the Danny Wallace Foundation, which supports both sufferers and carers, receives a huge boost to its coffers.
"It has been hard. I walk about a mile and then I have a break," he told the South London Press.
"I knew it was going to be a difficult thing for me to complete but I am determined, and as the miles have gone by I have settled into my stride.
"I am so pleased I will be raising cash for other sufferers and doing something really positive."
Wallace was joined by former boxer Michael Watson for part of the course on Wednesday.
Watson, who suffered from terrible brain injuries following a bout with Chris Eubank in 1991, completed the course in six days in 2003.
