Stage (bicycle race)

In sport
s, a stage, or leg, or heat, is a unit of a race
which has been divided in several parts for the reason such as length of the distance to be covered, as in a multi-day event. Usually, such a race consists of "ordinary" stages, but sometimes stages are held as an individual time trial
or a team time trial
. Long races such as the Tour de France
or the Giro d'Italia
are known for their stages of one day each, whereas the boat sailing VELUX 5 Oceans Race
is broken down in usually four stages of several weeks duration each, where the competitors are racing continuously day and night. In bicycling, a race with stages is known as a stage race.

s is crucial to race tactics: a lone rider has little chance of outracing a small group of riders who can take turns in the strenuous position at the front of the group. The majority of riders form a single large group, the "pack" (in French
, the "peloton"), with attacking groups ahead of it and the occasional struggling rider dropping behind. In mountainous stages the peloton is likely to become fragmented, but in flat stages a split is rare.
Where a group of riders reach the finish line together, they do not race each other for a few seconds of improvement to their finishing time. There is a rule that if one rider finishes less than one second behind another then he is credited with the same finishing time as the first. This operates transitively, so when the peloton finishes together every rider in it gets the time of the rider at the front of the peloton, even though the peloton takes tens of seconds, and possibly even a couple of minutes, to cross the finish line.
Riders who crash within the last kilometre of the stage are credited with the finishing time of the group that they were with when they crashed, if that is better than the time in which they actually finish. This avoids sprinters being penalised for accidents that do not accurately reflect their performance on the stage as a whole given that crashes in the final kilometre can be huge pileups that are hard to avoid for a rider farther back in the peloton. A crashed sprinter inside the final kilometre will not win the sprint, but avoids being penalised in the overall classification.
Mountains cause big splits in finishing times due to the simple laws of physics. Firstly, the slower speeds mean that the aerodynamic advantage gained by slipstreaming is much smaller. Furthermore, lighter riders generate more power per kilogram than heavier riders; thus, the sprinters and the rouleurs (all-around good cyclists), who tend to be a bit bigger, suffer on the climbs and lose lots of time—40 minutes over a long stage is not unheard-of. Generally, these riders form a group known as the "bus" or "autobus" and ride at a steady pace to the finish. Their only goal is to cross the line within a certain limit—usually the stage winner's time plus 15% -- or else they'll be disqualified from the race (at the discretion of the officials; on rare occasions a lead breakaway becomes so large that the entire peloton falls that far back and would normally be allowed to remain in the competition to avoid having only a small field still in competition).
Meanwhile, the lighter climbers hurl themselves up the slopes at a much higher speed. Usually, the General Classification riders try to stay near the front group, and they also try to keep a few teammates with them. These teammates are there to drive the pace—and hopefully "drop" the opposition riders—and to provide moral support to their leader. Typically, the leader will attack very hard when there are only a few kilometers to go, trying to put time into his main rivals. Gaps of two and even three minutes can be created over just a few kilometers by hard attacks.

A crashed sprinter inside the final kilometre will not win the sprint, but avoids being penalised in the overall classification.
Stages in flat terrain
Ordinary stages can be further classified as "sprinters' stages" or "climbers' stages". The former tend to be raced on relatively flat terrain, which makes it difficult for small groups or individual cyclists to break away from the peloton—there are no big hills to slow it down. So more often than not, the entire peloton approaches the finish line en masse. Some teams are organized around a single specialized sprinter, and in the final kilometers of a sprint stage, these teams jockey for position at the front of the peloton. In the final few hundred meters, a succession of riders "lead out" their sprinter, riding very hard while he stays in their slipstream. Just before the line—200 meters away is about the maximum—the sprinter launches himself around his final lead-out man in an all-out effort for the line. Top speeds can be in excess of 72 km/h (about 45 mph). Sprint stages rarely result in big time differences between riders (see above), but contenders for the General Classification tend to stay near the front of the peloton to avoid crashes.Mountain stages
Mountain stages, on the other hand, often do cause big "splits" in the finishing times, especially when the stage actually ends at the top of a mountain. (If the stage ends at the bottom of a mountain that has just been climbed, riders have the chance to descend aggressively and catch up to anyone who may have beaten them to the summit.) For this reason, the mountain stages are considered the deciding factor in most Tours, and are often attended by hundreds of thousands of spectators.Mountains cause big splits in finishing times due to the simple laws of physics.

Medium mountain stages
In larger stage races, some stages may be designated as "medium mountain" stages, or "intermediate" stages. These stages are more difficult than flat stages, but not as difficult as the mountain stages. They are often well-suited for a breakaway (as described below). Occasionally, the distinction between medium mountain and mountain in stage classification, decided by race officials, can be controversial. The Giro d'ItaliaGiro d'Italia
