How does a lead climbing competition work?
B · Beginner · The route and the score · 1 of 3Each climber gets one attempt at a tall route, on a wall at least 15 metres high, with a rope that they clip into fixed points as they go. They have six minutes. The result is how high they got: the last hold they controlled, or a top if they clip the final anchor.
How it works
- The wall: not less than 15 m high and at least 3 m wide for each route.
- Roped from below: climbers are "belayed from below, secured by clipping the rope through a series of quickdraws".
- One attempt: "a single scoring attempt on a route in any round".
- The time: six minutes in world series events. The competition rules say it should not exceed six.
- Three rounds: qualification on two routes, then a semi-final and a final on one route each.
- How many climbers: up to 80 in qualification, 24 in the semi-final and 8 in the final.
- Flash, then on-sight: qualification routes are demonstrated beforehand. The later rounds are climbed without having seen anyone on the route.
- A last look: on walking out, each climber has 40 seconds to look at the route and get ready.
- The start: the attempt begins when the climber leaves the ground.
- The belayer: checks the knot and harness, keeps the rope neither tight nor slack and lowers the climber afterwards.
- Starting order: in the semi-final and final the best ranked climbs last.
The glossary has the lead event format, lead climbing, the attempt, the climbing time, the belay entry and the quickdraw.
Tricky cases
A climber slips off near the bottom. Can they start again?
No. A climber makes a single scoring attempt, and a fall ends it. A restart is possible only after a technical incident.
The six minutes run out with the climber still on the wall. What is the result?
The attempt is ruled unsuccessful when the time expires, and the result is the last scoring hold they had controlled.
In qualification, does a climber's result on the second route replace the first?
No. Both count: the ranking on each route goes into the qualification points.
How long does a climber rest between two qualification routes?
At least 50 minutes between finishing one and starting the next.
Why the rule exists
Lead tests endurance and reading a route under pressure, and a single attempt is what makes it tense: one slip ends the round. The time limit stops a climber from resting for long spells on good holds and keeps a round of 24 within a session.
