Each event is a six hour timed challenge event based out of the Cyclopark Complex at Gravesend (although the routes won't actually be in the Cyclopark area). The route is a mixture of trail, bike paths and tarmac and although it's not flat there's not too many hills!
Runners are invited to complete as many loops within the time limit. Run a marathon, run an ultra, run less, as long as you complete one loop you're a finisher!
