Hiking is one thing. Hiking with major elevation changes and lots of miles is quite different. I would recommend walking at least three miles a day 3x4 times a week starting a month prior to your trip to get your body used to it and gradually increasing as time grows closer. We do small trips like that before our big trips and it seems to help quite a bit. We went to Oregon in June and hiked @ 40 miles over 6 days and last year in Utah, we did @ 60 miles in 7 days.
