This epic Mountain Biking Backcountry Tibet tour is a challenge is best described as adventure biking, designed for two-wheeled mountaineers. There are riders for whom 2-3 hours of climbing is worth an hour or more of non-stop descent. For these riders, when burning muscles and desperate pedal strokes are overshadowed by the seemingly futile experience of breathing, by screaming lungs gasping for one more mouthful of oxygen, their smiles get bigger and their sense of adventure grows deeper.
