Quick answer
A false start occurs when an athlete initiates the start outside the permitted procedure. Because sanctions and detection rules are competition-critical, current World Climbing rules—not an old summary—should be used for exact thresholds and consequences.
Why false starts matter so much
The start is one of the few moments when trying to gain a tiny advantage can immediately destroy a race. Elite margins are measured in hundredths, but anticipation must remain inside the legal start procedure.
How starts are detected
Modern Speed uses electronic start and timing equipment. This reduces dependence on a human observer’s reaction time and allows the competition system to determine start events according to the applicable rules.
Why we do not publish a permanent threshold here
Rule wording, thresholds and sanction procedures can change. A number copied from an old championship can become misleading. SpeedClimbing.com therefore explains the concept and points competitors to current World Climbing competition resources for the operative rule.
Training reaction without training guessing
Use realistic signals with variable timing so the athlete responds rather than memorizes a countdown. Evaluate the first several moves, not only the initial reaction. A marginally quicker launch that damages the next contact is not a better start.
What spectators should watch
If a race stops unexpectedly at the start, wait for the official decision. Do not infer the ruling solely from television audio, visible movement or an unofficial replay; the timing/judging system and current rules govern the result.
