Enduro mountain biking is a type of mountain bike racing that combines elements of all racing disciplines, including cross-country and downhill racing. In enduro racing, riders are timed in stages that are primarily downhill, with neutral "transfer" stages in between). The downhills are timed, and the uphills are mandatory but not timed). Enduro racing is a multi-stage racing format comprised of timed downhill runs throughout the course of the event, which can be one day or multiple days, with anywhere between three to six stages per day. Between each stage is an untimed transfer, which is typically a climb. Enduro racing requires a bike that can both descend hard and climb efficiently. Enduro bikes are long-travel mountain bikes, meaning that they have more suspension than a typical trail bike, usually between 150-180mm of travel. Enduro mountain biking has quickly grown in popularity to become one of the most predominant genres of mountain biking. It has been a major component in shaping not only how we ride but the bikes we are riding.
