What time you generally leave to go up a hill in October? 4 hour route. Petty argument sorry.
Settle an argument as I'm feeling bored (and curious if im over cautious). If hill is quick I would still leave early to start route at 8am (gives you plenty of light if things go wrong etc). Friend says start after midday as route is only 4 hours.
Personally if the only good sunny weather window was the afternoon, I'd still leave early, or if it was horrendous in the morning I'd consider just not going up.
