a time-limit, but are not part of the accumulated time. The winner is the rider who accumulates the lowest combined time from the timed downhill sections. Enduros typically take place over one or two days, but week-long competitions also exist. A typical one-day enduro consists of 3 to 5 timed stages which take place on technically demanding, generally descending terrain, often with sections of singletrack. Stage Races (XTS) – Stage Races consist of several races – 'stages' – ridden consecutively, usually over a period of several days. A stage is usually similar in length and structure to a Marathon mountain bike race. The competitor with the lowest cumulative time to complete all the stages is declared the overall, or General Classification (GC), winner. Stage races may also have other classifications and awards, such as individual stage winners. Bike trials – Slow negotiation of man-made and natural obstacles where setting a foot down constitutes a penalty. Dirt jumping – Dirt jumping (DJ), similar to freeride, it is a competition of skill, differing that it involves the rider to jump off mounds of dirt to perform the best tricks with the best style. It differs to freeriding that the jumps are usually much larger and designed to lift the rider higher into the air and the bicycle is different from its counterpart. Mountain bike orienteering (MTB-O or MTBO) is an orienteering sport on a mountain bike where navigation is done along trails and tracks. The major focus becomes route choice while navigating at bike speed. Special equipment used is a map holder attached to the handlebar of the bike. The sport is governed by International Orienteering Federation. 24 hour mountain bike races are a form of endurance mountain bike racing where solo competitors or teams race for a period of 24 hours and standings are based on who has ridden the furthest distance in that time (typically, the most number of laps around a loop). Notable events The main events in mountain bike racing are the cross-country event at the Summer Olympics and the World Championships and World Cup organized every year by the UCI at various venues around the World. There are also other notable events in some countries, like Crankworx, a week-long event in Whistler, British Columbia, Canada; MTB Himalaya in India; Chupacabras, a race in Juárez, Mexico; The Nedbank Tour de Tuli in South Africa, Zimbabwe and Botswana, Cape
