Luray Classic is a 83 mile loop trail located near Front Royal, Virginia and is only recommended for very experienced adventurers. The trail is primarily used for road biking and mountain biking and is accessible year-round.
My legs burned for a week. Okay, so I got a room and did it in two days, but at least I did it. Next time I will find a ride with a lot less vertical. My mountain bike is a lot of work for a cruise like this.
