My best friend and I have been hiking and scrambling in the mountains together for a couple of decades now. Back in the early Noughties we decided that we would complete our own version of the Three Peaks every 4 years until one of us croaks. The survivor then completes the challenge in the next due year on a in memoriam basis. Our rules are simple; All three peaks completed in one calendar year. Total walking time to be less than 24 hours (ex' summit stops) - although in reality if we exceeded this time we'd not beat ourselves up - especially as we are heading into old age. Our next challenge is in 2018 (this is one year overdue due to illness on my part) - again we are not going to fret about this. Crap happens in life. Our routes for 2018 are as follows: Snowdon - 5 Nails from Pen-y-Pass. Scafell Pike - Bit of a biggie this one but something we've wanted to do for a while now. Cockly Beck > Little Stand (nice scramble) > Crinkle Crags > Bowfell > Esk Pike > Scafell Pike > Scafell > Slight Side > The Woolpack Inn. This route might impact quite heavily on the 24 hr overall target time. Ben Nevis - Glen Nevis Gorge Car Park > Carn Mor Dearg via East Ridge > Ben Nevis via CMD Arette > Carn Dearg > Glen Nevis. Another hefty day and we may decide against the descent from Carn Dearg and take the Tourist Track down instead - will depend on how tired we are. Neither of us have descended from Carn Dearg before but I have ascended and from what I remember (did it sometime in the nineties) it is was very steep and a bit loose in places. *** Anyone else have any reoccurring mountain challenges in their life?
