Rabbi Landau, 28, cycled 20 miles with a damaged bike before he could find a mechanic to fix it. "I wanted to power through and finish after that, which I did. But I didn't get the time I'd hoped for, so I'll have to do it next year."
He was introduced to long-distance cycling last year by the chair of his south London shul, Dr Martin Wolfson, who completed Sunday's event on behalf of World Jewish Relief.
"We used to conduct meetings on our bikes in Richmond Park," Rabbi Landau said. "I knew how to ride a bike but nowhere near this level. Since then I've become faster and more meshuganah about it. I cycle really early in the morning, before my daughter Yiska wakes up, and do about 150 miles per week.
"In terms of mental health, it's a very stabilising activity."
Also riding for Jewish Care were Chigwell-based Rod Epstein and Richard Pearlman, who respectively raised £1,000 and £4,500.
Miles Allen, Mendy Freundlich, Shloime Kaufman, Johnny Marks, David Nathan, Abe Rosenfeld, Joel Sager, Alex Schajer, Simon Selouk and Moishe Vogel rode for learning disability charity Kisharon, raising a combined £8,000-plus. Kisharon CEO Dr Beverley Jacobson and her husband Alan also took part.
Mr Allen was the fastest finisher in 4:26. "It was exhilarating and I really enjoyed it," he said. "This was my first time riding for Kisharon. I entered on a previous year but got three punctures and couldn't finish. This time I set off early and I was very pleased with my time."
Cyclists Martin Wolfson and Dan Rickman raised more than £2,000 for World Jewish Relief and Simon Rosenblatt did the event for Norwood.
