A climbing competition (or comp) is usually held indoors on purpose-built climbing walls. There are three main types of climbing competition: lead, speed, and bouldering.

In lead climbing, the competitors start at the bottom of a route and must climb within a certain time frame, making sure to clip the rope into pre-placed quickdraws along the route. Speed climbing can either be an individual or team event, with the person or team that can climb a standardized route the fastest is the winner. Bouldering competitions consist of climbing short problems without a rope, with the emphasis on the number of problems completed.
