Mountain biking is a sport which consists of riding bicycles off-road, often over rough terrain, using specially adapted mountain bikes. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain.
Mountain biking can generally be broken down into multiple categories: cross country (XC), trail riding, all mountain, downhill, freeride, street riding, dirt jumping and trials. The vast majority of mountain biking falls into the recreational XC, and Trail Riding categories.
Rock climbing is a sport in which participants climb up or across natural rock formations or artificial rock walls. The goal is to reach the summit of a formation or the endpoint of a pre-defined route without falling. Rock climbing competitions have objectives of completing the route in the quickest possible time or the farthest along an ever increasingly harder route. Rock climbing is similar to scrambling (another activity involving the scaling of hills and similar formations), but climbing isgenerally differentiated because of the use of hands to support the climber's weight as well as to provide balance.
Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with her or his mental control. It can be a dangerous sport and knowledge of proper climbing techniques and usage of specialized climbing equipment is crucial for the safe completion of routes.
