The ultra event was won by Tom Marshall in 4:22:43 and Vikki Sivertsen in 5:04:27.
The course in Richmond Park, the host for all ten previous editions of the event, is the largest of the capital’s eight Royal Parks and the biggest enclosed space in London, provided the perfect setting for the competitors.
The event was started in 2005 and has grown in popularity each year. Public places for this year’s event sold out four months before race day, and the final Ultra finisher crossed the finish line just after 5pm having run and cycled well over 100km.
