What happens if a pentathlete falls off an obstacle?
I · Intermediate · Obstacle and swimming · 5 of 7The judge raises a yellow flag and calls "Fail". This is a warning, and the athlete may go back and try that obstacle again while the clock keeps running. A second failure on the same obstacle brings a red flag and "Stop". The athlete is eliminated, scoring zero for the obstacle event.
How it works
- First failure: the course judge raises a yellow flag and calls "Fail", "which corresponds to a warning".
- Going again: the athlete goes on to the end of the obstacle, turns round the frame and returns to its start along the outside.
- Second failure on the same obstacle: a red flag and "Stop". The athlete must leave the course at once.
- What it costs: elimination, which means zero points for the event but not the end of the competition.
- Touching the ground: forbidden between the platforms on the hanging obstacles.
- Mats and trusses: contact with the crash mats or the vertical trusses is a failure unless nothing was gained from it.
- Starting counts: putting weight on an element is the start of an attempt.
- Stepping back: starting an obstacle and then stepping back onto the take-off platform is a failure.
- Wrong lane: crossing into the other lane on a hanging obstacle means elimination.
- Obstructing: jostling or impeding the other athlete means disqualification.
- Before the wall: an athlete who failed the obstacle before the finish wall may be stopped before they start to climb it.
- Ignoring the judge: not following an official's instruction after a failed attempt means elimination.

Tricky cases
An athlete fails the big wheel once and the tilting ladders once. Are they eliminated?
No. Elimination follows a second failure on the same obstacle.
An athlete hangs from the first ring, changes their mind and steps back onto the platform. Is that a failure?
Yes. Starting an obstacle and then stepping backwards onto the take-off platform is a failure.
An athlete is eliminated on the sixth obstacle. Can they still swim?
Yes. An eliminated athlete scores zero in that event and may compete in the events that follow.
After a failure, can the athlete touch the frame on the way back?
Yes. Touching the trusses and running over the side mats while returning carries no penalty.
Why the rule exists
One retry keeps a single slip from wiping out an athlete's event, while the time lost going round is its own penalty. Stopping the athlete at the second failure keeps the race moving and prevents a tired athlete from trying a hanging obstacle again and again.
