Scouting 100k gravel permanent routes. 63mi, 7300ft. 505 and 68J are probably too chonky for reasonable people. This is doable in the RUSA permanent time limit, but you’d have to pack all of your food and hustle. It goes Boulder > Lefthand > Lickskillet > Gold Hill > Rainbow Lakes > 505 > Caribou Rd > Nederland > Magnolia > 68J > Flagstaff > Boulder
