Yeah, it will be an interesting experience when I do my first tour. I’m used to riding (relatively) fast on the road, but the bike I use for that has narrow tires and no provisions for racks or anything like that. I built a gravel bike for touring that weighs about 7.5 lbs more than the road bike (steel vs aluminum frames, so that’s not a surprise) and has tires that are not slick, so it’s both heavier and has a higher rolling resistance. But it’s supposed to be a comfortable, all-day tourer.

For packing, I think my biggest question is, how many days of clothes? For example, if I were doing that GAP/C&O trip in, say, 5 or 6 days, I think I’d want maybe 3 outfits - if it rains one day, I wouldn’t want to put those on the next day, unless they’ve somehow dried already. Things like socks I can reuse, usually, but again if they get really wet, I’m not going to want to wear them again until they dry - but socks are also the easiest things to pack extra of. And I’d probably want at least one set of clothes to wear in the evening after a shower. Stuff like that is my biggest question.

I realize different people are going to pack differently, of course.

My brother lives just over 100 miles away by bike, and most of the trip is on either actual bike trails or at least on designated bike routes (East Coast Greenway, US Bike Routes, etc.) - only the first few miles by my house aren’t, and those are roads I’m very comfortable with, and the last mile or so to his house. Riding there one day and back the next would be a good test ride, I think.
