Nice one! Route copied over to the Wahoo.
Gearing wise, I'm going for 47x19 I think which is just under 66".
Oh really? Jeez, what kind of hills are we doing? Like Tuesday night hills for 66 miles?? So 72" is going to be uncomfortable then. Might need to get a 18t and new chain. Luckily I think I lost a kilo or so from my week in Morocco.
Route looks suitably hilly, then again there are tales of doing a 10 mile TT and then riding home over Mam Tor on 84" so make of that what you want!
