recently back from a successful solo unsupported completion of the Rigby round of the cairngorms. will write something later, but suffice to say the conditions were appalling and it was a matter of survival after the first 10 hours. got really, really lost. took 54 hours without sleep in the end (despite doing first 8 munros out of 18 in 13 hours) due to getting lost and exceptionally demanding conditions. now have frostnipped fingers and feet. An amazing experience to look back on. in good weather and with a moon it would have been a quite different experience (and a much shorter one) but in some ways I'm not sure that it would have been better. once i've got the time I'll write a bit more.
