This past August I completed a 147 mile mountain bike ride in the SouthWest corner of Colorado called the San Juan Hut-to-Hut trip. Starting in Telluride Colorado and finishing in the lovely little town of Gateway Colorado, the ride leverages a fortified hut system stitched between miles of forest access roads and light single-track.

Preparing for a 5 day trip like this eventually came down to loading your bike up with panniers OR loading your upper-back up with a massive bag. Water and protection from the elements came first, with bike parts and sundry maintenance items not far behind. A close third was food and a flask of Gentleman Jack. In total, we were expecting to carry an additional 25-30 pounds of gear (which included daily water needs).
