Meet the man who will ride 500km around Regent's Park

London cyclist Justin McKie is going to ride 500 kilometres for charity - but he isn't undertaking a mammoth trans-continental haul. Instead, he will ride 113 laps of the Outer Circle of Regent's Park on October 3 in a 'Zoodax' to raise funds to plant new trees in the iconic green space.

"Cyclist numbers have grown in London and in Regent's Park particularly and we want to say thanks," said McKie, who belongs to the Regent's Park Cyclists group.

"With pollution levels killing thousands each year we need more trees (and less cars). With cyclists getting killed in London, Regent's Park is our safe haven to exercise in London. There are no others. "

Money raised by McKie's efforts will go to a fund that will replenish the park's landmark cherry trees, which blossom in pink every spring. The idea is for cyclists to put something back into the park that they use and love.

Donations can be made via the Regent's Park Cyclists Money Giving page.

Regent's Park Cyclists' mission is to promote and support responsible cycling in the park.
