I am a biker of about your speed.With friends, I completed the GAP/CandO in 2014. Yes, you can do the CandO in 4 days. We will be riding the CandO again this year beginning on July 8. We will overnight in Cumberland, Hancock, Shepardstown, and Leesburg. Then we will stay in DC. Other than Day 1 being @60 miles (plus whatever the PawPaw tunnel detour adds), our days are about 40+ miles each.
