In reply to Full moon addict: Old mate of mine (Mike Sheldrake) did a sub-24 hour round of Coruisk many years ago - late 70s. Main Cullin ridge but I don't know what peaks he went over after Gillean - I think it included all the greater traverse + some more peaks. Certainly at the time there was no 24 hour challenge like that on Skye and it's quite possible that he was the first to do such a sub 24 hour circuit there.
