I had an E - mail from the organiser (Dan) today, it reads: 'The trickiest part of the course is the first section through the forest. Once you’re through that part it’s a fairly simple trail to follow.

Please be advised that although it says the 1st manned checkpoint closes at 10:15, this is due to be changed after a number of runners raising concern about covering the distance if they were to set off at 9:30.

The times will all be confirmed after my site visit early next week.
