A criterium is a type of bicycle race that takes place on a short, closed circuit, often in urban areas. These races are typically fast-paced and feature multiple laps, allowing spectators to see the action up close. Riders compete against each other, and the winner is usually the first to cross the finish line after completing a set number of laps. Criteriums are popular in the cycling community because they showcase the riders' skills in cornering and sprinting. They often attract large crowds and can be part of larger cycling events or festivals, making them an exciting experience for both participants and fans.
