A criterium, or crit, is a bike race consisting of several laps around a closed circuit, the length of each lap or circuit ranging from about 400 m to 10,000 m. Overview Race length can be determined by a number of laps or total time, in which case the number of remaining laps is calculated as the race progresses. Generally the event's duration (commonly one hour) is shorter than that of a traditional road race — which can last many hours, sometimes over the course of several days or even weeks, as in a Grand Tour. However, the average speed and intensity are appreciably higher. The winner is the first rider to cross the finish line without having been "lapped". Events often have prizes (called primes and are usually cash) for winning specific intermediate laps (for instance, every 10th lap). A bell is usually rung to announce to the riders that whoever wins the next lap, wins the prime. Success in road criteriums requires a mix of good technical skills — in particular, the ability to corner smoothly while holding the line on the road, as well as rapidly and sharply — and riding safely with a large group on a short circuit and exceptional "sprint" ability to attack other riders and repeatedly accelerate hard from corners. Criteriums are relatively easy to organise, do not require a large amount of space, and are good for live spectators as they allow them to see the riders pass by many times. They are the most common type of bicycle racing in the continental United States. They are also gaining popularity as a format for mountain bike events. Belgium's Flanders region hosts a number of criteriums, as does the Netherlands. The most notable of these are held in late July and early August, just after the Tour de France. However, criteriums in Europe are mostly held in the format of a points race. First, second, and third rider at every 5th lap gets 3, 2, 1 points respectively, with double points for the final sprint. It was a long tradition that after the Tour these criteriums were fixed to have favourable results for local favourites, who may be participating for show after having ridden in a larger race such as the Tour de France. Equipment Racing bicycles used for Criteriums often have subtle, but significantly different geometry from those used in other mass-start,
