And just to clarify, don't be discouraged by this if you don't already use/own that gear. You don't have to spend a bunch of money on specialty stuff and ride with a biker diaper and go commando to be comfortable. Some decent fitting undies(synthetic boxer briefs are my favorite) and a decent seat are probably good enough. I ride in boxer briefs designed for athletic activity and regular shorts and I can do 60mi perfectly comfortably(never tried more). Same story for my touring partner. If you used to ride 80-100km on the weekend, you know what works for you. Just start getting in miles whenever you possibly can and go rock that trip!
