^ A lot of sense.
I did it in 2014. I set off in the warm sun but had heeded the advice and had a gilet and arm warmers. Half way round the heavens opened and it got cold.
It’s a tough course – not WW territory IMHO. At times the climbing is mental. I had a triple and 11-36 and was glad of it. Next time I’ll use an auxiliary battery for my Garmin.
In 2014 a number of very fast people converted to the 100k – don’t start fast – you’re probably aiming for about 13hrs for the 100miler?
It is VERY rocky. At one point you’ll descend through a track consisting of boulders the size of TVs.
It’s also great fun with a tremendous atmosphere!
