Agree. When I rode from SF to LA, 10-15 miles was the "warm-up" portion of my average training ride! I found the ride tough, but enjoyable... but I had a relatively light bike, 30 gears to choose from and a low gear of around 26". Personally, it sounds to me like the OP is either 1) a troll, or 2) completely unprepared for the proposed trip.
