Question

What`s the longest bike trail in america`s mainland?

Answer 1

The "Great Divide Route" is 2,500 miles of rough fire roads that cross summits of the Continental Divide 27 times, earning you over 200,000 feet in changed elevation. The entire trail stretches from Canada to Mexico. It will take an ordinary human 3 months to complete. But unlike any other transnational trail in North America you won't be squeezed by cars as you ride from border to border. It's a remote trail, in wilderness, with few amenities. Think of it as the Appalachian Trail for bicycles.
