How Modern Pentathlon Scoring Works
The Modern Pentathlon is a multidisciplinary sport consisting of fencing, swimming, equestrian show jumping, and a combined laser-run (pistol shooting and cross-country running). The scoring system is designed to normalize performance across these diverse activities.
1. Fencing (Ranking Round)
In a standard competition with 36 athletes, each athlete faces every other athlete in a one-minute bout. Achieving 25 victories (70% of bouts) earns 250 points. Every win above or below this mark adds or subtracts a specific number of points (usually 6 points in the 36-athlete format).
2. Swimming (200m Freestyle)
A time of 2:30.00 earns 250 points. For every 0.5 seconds faster or slower than this target, 2 points are added or subtracted. This equals 4 points per full second.
3. Equestrian (Show Jumping)
Athletes start with a perfect score of 300 points. Deductions occur for penalties: 7 points for a knockdown, 10 points for a refusal or fall, and 1 point for every second over the time limit.
4. Laser Run (The Combined Event)
The final event is a handicap start based on points earned in the previous three rounds. However, for raw scoring, a time of 13:20.00 (800 seconds) is worth 500 points. Each second faster or slower is worth +/- 1 point.
