Oiy, so glad you are ok. I’ve never done anything even 1/1000th that difficult so have no advice to give other than that you probably shouldn’t do such epics by yourself (though good luck finding someone crazy enough to volunteer). Lots of protein, sleep, and stay off the bike a bit to give your body time to repair itself. Sounds like you just biked the equivalent of a marathon.
I saw a fair number of riders out and about. There was some kind of group ride or event in Luray I think. I saw quite a few identi-kitted groups riding in packs.
Or maybe it wasn’t their kits. Maybe it was the spots before my eyes…
