A "criterium" is a type of bicycle race that takes place on a closed circuit, typically featuring a short course of about 1 to 2 kilometers. These races are often held on city streets and can include sharp turns and elevation changes, making them exciting for both participants and spectators. Criteriums are usually timed events, with riders completing as many laps as possible within a set time limit. Criteriums are popular in competitive cycling, especially in the United States and Europe. They are often part of larger cycling events or festivals and can attract a wide range of participants, from amateur cyclists to professional racers. The fast-paced nature of criteriums emphasizes strategy, speed, and bike handling skills.
