The Lakes 24                                                                  Lakes

This route of 71 miles and 29,200 feet, devised and completed by Chris Upson, won the FRA Long Distance Award in 2003.  It ascends 24 Marilyns in 24 hours.  The start is at Martindale Hause, near Ullswater and the finish is on the summit of Swinside not far from Derwentwater.  The term 'Marilyn' was conceived by Alan Dawson in his book "The Relative Hills of Britain" which defines it as a hill with a drop of at least 150 metres, or roughly 500 feet, on all sides, in a similar way to the Scottish Corbetts.  This ignores absolute height, the distance from other hills and topographical merit to give a list of more significant, individual hills. It also excludes what some might consider to be "soft touch" hills that feature in some of the UK Big 3 rounds and their extensions.

As a worthy alternative to the Bob Graham, The Lakes 24 brings variety, objectivity and a fresh perspective to a view that may have become a little blinkered over the years. Surprisingly it has still to be repeated!
