The Glen Lyon Corbett Round                                     Scotland

Corbetts are Scottish hills of between 2500' and 3000' in height with a drop of 500' on all sides. In contrast to the Munros this definition ensures they are all separate well defined peaks with a significant ascent.  There are 221 listed in total and this route links together the 13 clustered round the remote and beautiful area of Glen Lyon, north-east of Tyndrum in the Central Highlands. It was devised by Yiannis Tridimas and was first completed as a solo run of 96km with 6000m ascent in a time of 22-42 during 2012 having previously clocked up a round of 12 Corbetts the year before. Like Yiannis's other routes it is characterised by formidable, pathless terrain making it no less demanding than most other 24 hour rounds! 


The object is to complete the round of 13 Corbetts listed below within 24 hours by starting and finishing at Stronuich Reservoir (GR NN 507 421)
