Oh yea, did 60 miles in March. Came in at Front Royal and parked the car at the first ranger station/bathroom area, about mile 2 or 3. Then 30 miles down and 30 miles back. It's a tough ride! You're either haulin' down a hill very fast, or slogging up a hill pretty slow. There are no flats. Up and down and up and down. Try to go on a week day if you can, there's almost no traffic. Weekends can get very crowded. Make sure you pack your own food and water too, there are very few places to stop for supplies. I wore a backpack with extra Gatorade and sandwiches. It's great fun though!
