Oh yeah, it's a bit rough if it's your first time that long on foot. My first long trek was during our big snow storm back in February. It came out to about 9 hours covering just about 9 miles that day. My legs killed me for a week. Now it's not so bad, walking 10-14 miles around town. Hopefully I can pull 18 to my parents house. Somebody will be driving me home, however.
