Tanner, Rut and Adam visit Germany for the ultimate high-speed road trip; they get to battle it out at top speeds on the legendary no-speed-limit Autobahn.

The Appalachian Trail spans 2,168 miles from Maine to Georgia, and takes 3 to 6 months to hike. But what if you don't have that kind of time? Tanner, Rutledge and Adam are given the monumental task of driving a road-based version of all 14 states on the trail in just 1 day. With just 24 hours to complete their task they barely have time to stop and must come up with all sorts of ideas to save time.
