Coniston Lakeland Marathon (Trail Race and Challenge) 3rd July 2011.
Both events had the same course; Challenge started 07:00, Trail Race started at 09:00.
Course was hilly in places, technical (rocks, climbs, tree roots, boggy bits, river crossing) but scenic.
[River crossing was temporary as local council had removed bridge for repairs, not presumed to be a feature for future years]
Reasonable water stations, but 18k gap between 2nd and 3rd. No biscuits, but plenty of Kendal mint cake.

Very enjoyable, definitely recommended.
One warning: Do not stop at peak for 15 seconds to take pictures for other people.....
