Who races whom in the pentathlon obstacle event, and what is a false start?
A · Advanced · Obstacle and swimming · 4 of 4In semi-finals and finals the start order is the reverse of the standings after fencing, so the lowest ranked race first and the leaders last. Athletes stand on a starting platform until the signal. Leaving it or beginning to move before the signal is a false start and costs 10 points. A blatant early start means disqualification.
How it works
- In qualification: by world ranking obstacle time, the slower athlete first and in lane A.
- In semi-finals and finals: "the reverse of the ranking following the Fencing event".
- An odd number: the athlete in the first heat races alone.
- Called up: on the long whistle athletes step onto the starting platform and stay there.
- "Take your marks": they take up a starting position, and the signal follows when both are still.
- False start: leaving the platform, or beginning the start movements, before the signal.
- The price: "a deduction of 10 points".
- Blatant: disqualification for "a blatant attempt to start too early".
- Late: a late starter is not penalised, but the time runs from the signal.
- Not there: an athlete absent after three calls a minute apart is eliminated.
- Hands: gloves, tape, chalk and sticky substances on the hands are not allowed, on pain of elimination.

Tricky cases
An athlete twitches on the platform before the signal but does not leave it. Is that a false start?
It is if they began their start movements before the signal. The starter is the sole judge.
An athlete reacts slowly and leaves a second after the signal. Is their time adjusted?
No. Their time is taken from the moment they should have started.
Can an athlete chalk their hands for the hanging obstacles?
No. The penalty table lists the use of gloves, tape, chalk or any sticky substance on the hands under elimination.
Who is in lane A in a final?
The lower ranked of the two after fencing.
Why the rule exists
Reversing the standings puts athletes of similar standing in the same race and saves the leaders for last, which builds the event for those watching. The 10-point price for a false start is about three seconds of obstacle time, far more than an early start could gain.
