The funds will allow young children to visit a residential camp in Wales.
A London Marathon runner from Surbiton insists she will not be challenging Paula Radcliffe to a run but has collected over £1,600 for a South West London charity.
Helen Brett, 56, director of business strategy for YMCA London South West, ran 26.2 miles to raise funds for the organisation.
Mrs Brett completed 59 training runs with a total of 383 miles in 15 weeks, while burning 32,250 calories in the process.
“It took me five hours, 52 minutes and 46 seconds, so Paula Radcliffe isn’t quaking in her boots just yet!” she said.
“It was a fantastic experience that I will never forget.”
Funds will go toward taking local children from vulnerable families for week-long activity and adventure holidays at a YMCA residential camp in Wales.
“Many of the runners were wearing black ribbons, and a 30 second silence acknowledged the Boston bombing,” she added.
“Refusing to allow such a devastating event to impact the spirit of the London Marathon, none of the runners that I spoke to had any doubts about being there. There was no question of not running.”
She completed the race without any injuries and the organisation thanked her and their sponsors for funding their community projects.
“We know that the young people who take part will really benefit from her big day and all the hard training that led up to it,” said Caroline Cronin, Head of Marketing & Communications of YMCA London South West.
Mrs Brett took up running in 2000 and completed a 16 mile half marathon in 2011.
YMCA London South West is a Christian charity that has been supporting the Kingston community since 1874.
