Those who complete (compleat!) the Munros can record this fact and receive the magic number by writing in to The Clerk of The List (See here). Additionally, a list of current compleaters is published annually in the SMC Journal.

My last Munro was An Riabhachan, which I combined with An Socach first from Glen Strathfarrar. The weather was lovely when I made this walk and the views were stunning, looking at so many Munros in the neighbourhood, a nice surprise for an event like this!
