Ran it (or large portions of to) in 2016, good challenge, pissed down the entire day spoiled it a bit. The last few flat miles back in to Horton from Ingleborough were grim on that limestone pavement though. Go for it ! If you want something local, check out the Charnwood Hills race, Anstey thru Braggy & the golf course to Beacon Hill and back roughly speaking. Organised by Bowline Climbing Club, usually entries go live in Oct ish for Feb race and it always sells out very quick. 14 ish miles.. https://www.bowlineclimbingclub.co.uk/hills-race
