A full marathon with height gain/loss of 6000 feet - Easily the hardest marathon in Britain. A run for really very exceptionally hearty man fellows and lady fellows, entirely on rough tracks, and including superb views over the North Downs, the Mole Gap, Denbies Vineyard, and Dorking, when you can wipe the stinging sweat from your eyes. 2018 will be the last year for this event.
