The Trial 100 is a list of Britain's greatest mountains. The popular walking magazine Trail asked their readers to vote. The mountains are categorised into nine geographic areas. It is a great list as it is not a mathematical formula or geographic significance, more a list of human significance and ultimately experience. The figures below are the Ordnance Survey spot heights and rounded up to the nearest feet. If you spot any mistakes or out of date figures due to re-surveying let me know. The ticks indicate which ones I have bagged.
