The Royal Parks Foundation is organising the event, which will start and end in Hyde Park on 12 October 2008.
Five categories of partnership are available to charities that want to get involved in the event, which will involve runners following a route through St James’s Park, Green Park and Kensington Gardens. The categories are Golden Oak Principal Charity (500-plus places), Silver Birch (250-plus), Copper Beech (100-plus), Elm (50-plus) and Sapling (50 or less).
Each place costs £117.50, with additional benefits ranging from a promotional area in the event’s charity marquee to a listing on the race website, depending on the category of partnership.
Sara Lom, chief executive of the Royal Parks Foundation, said the event would give small and medium-sized charities that are unable to get places in events such as the London Marathon a chance to participate.
“So many runs are in royal parks that we thought it was time to have one of our own,” she said.
