Boulder

An explosive performance on routes (problems) with a maximum height of 4 metres and safety mats below. The athlete who solves the most problems in the lowest number of attempts wins.

• Boulder competitions take place on 4-metre-high walls equipped with safety mats.
• The aim of Boulder is to solve (complete) the most problems (routes) on four/five (round-dependent) boulders in the lowest number of attempts over a given period of time.
• Different problems are set for men and women.
• The problems are reset between the Qualification, Semifinals and the Final.
• In Finals, competitors can preview the boulder problems during a collective observation time (2 minutes per Boulder) but cannot attempt the problems. In Qualifications and Semifinals, the climbers observe the problems for the first time during their first attempt (no observation prior to the round).
• Competitors are kept in an isolation room before they perform their “on sight” attempt.
• The Boulder ranking is decided by the number of problems solved. The competitor who solves the most problems wins.
• One zone hold (approximately the halfway point on a problem) is set per problem.
• The Boulder ranking is based on: 1. Number of tops reached, 2. Number of zone holds reached 3. Number of attempts to top, 4. Number of attempts to zone.
