Frazer Jackson from Mile End joins workmate Kafi Kawafi from Finsbury Park and other colleagues at REPL consultancy and technology group on the route from Putney Bridge to Henley.

"People can go at their own pace," Frazer explained. "But some of us are aiming to do the whole route continuously without an overnight break. It's a test of endurance rather than a race."

More than 3,000 people are expected to take part fom 7am.

Molly Olly's Wishes was set up in 2011 following the death of Rachel and Tim Ollerenshaw's eight-year-old daughter Molly from a rare kidney cancer.

The charity grants children with terminal or life-limiting illnesses with their wishes and donates therapeutic toys and books to the youngsters and to hospitals.

The charity's mascot is a toy lion called Olly who has his own detachable mane which helps to explain and normalise the effects of chemotherapy.

Wellwishers can donate to Molly Olly's Wishes online.
