Camp Simcha's work with children with serious illness and their families has benefited by £16,000 as a result of its marathon squad.
Michael Jaeger, Jonny Phillips, Dalia Davis, Shlomi Rokach, Edward Tricker, Jonathan Taieb and David Rosenthal recorded times ranging from 3:30 to 5:49.
Mr Phillips was the quickest, on his fourth marathon for the charity.
"I'm feeling really good, especially because I did my personal best time," he said.
"I always run for Camp Simcha because I love what they do, particularly the focus they put on helping the whole family."
Mr Jaeger will also run the New York race as part of his fundraising effort. He is backing Camp Simcha because a son of friends is supported by the charity.
'I have seen first-hand the life-changing work Camp Simcha does," he said. "No one wants to be in that situation but Camp Simcha does amazing work to help families who are."
Chief executive Neville Goldschneider thanked runners for their commitment. They have raised a fantastic amount to help continue making that critical difference to families who need us."
Other charity runners included Leeds student chaplain Rabbi Eli Magzimof (5:05), who raised £1,400-plus for University Jewish Chaplaincy; Harvey Kaye (3:27), who earned £2,300 for Langdon; Adam Myeroff (3:43), who raised around £4,000 for Breakthrough Breast Cancer and additional funds for Langdon; and Antony Berkin (3:56), who brought in £3,400 for the Joely Bear Appeal.
