That's only 30 mins longer to cover an extra 5-6 miles.
I've walked the 3P a handful of times and jogged it slowly during jan / feb this year (stunning blue sky day covered in snow - definitely one of my favourite days out of the year). Aim to do the race next year. Obviously to date I've not done the race route up whernside which I can imagine kills the legs a lot!
Any idea what the FTOP winning time was this year? 2.10 seems a lot faster than I saw anyone running. First runner overtook me just after CP5 which is only halfway-ish and that was around 12pm I think. I guess a time of 2.45?
