How heptathlon scoring works
The heptathlon is a two-day, seven-event competition for women in track and field. Rather than ranking athletes separately in each event, it converts every mark into points using the official World Athletics (formerly IAAF) combined-events scoring tables, then adds the seven point totals together. The athlete with the highest sum wins. This calculator applies those exact tables so you can score a full competition or a single event from your own marks.
The seven events, in order
- Day 1: 100 metres hurdles, high jump, shot put, 200 metres.
- Day 2: long jump, javelin throw, 800 metres.
The scoring formulas
Every event uses one of two formulas, and the points are always truncated down to a whole number (never rounded up):
- Running events (hurdles, 200 m, 800 m): P = a × (b − T)c, where T is your time in seconds. A faster (smaller) time gives more points.
- Jumps and throws (high jump, long jump, shot put, javelin): P = a × (M − b)c, where M is the distance or height. Jumps are measured in centimetres and throws in metres. A larger mark gives more points.
The constants a, b, and c are fixed for each event and set by World Athletics. The parameter b is the "baseline" mark worth zero points, so a mark at or below b (or a time at or above b for runs) scores nothing.
The official coefficients
| Event | a | b | c | Unit of M/T |
|---|---|---|---|---|
| 100 m hurdles | 9.23076 | 26.7 | 1.835 | seconds |
| High jump | 1.84523 | 75.0 | 1.348 | centimetres |
| Shot put | 56.0211 | 1.5 | 1.05 | metres |
| 200 m | 4.99087 | 42.5 | 1.81 | seconds |
| Long jump | 0.188807 | 210 | 1.41 | centimetres |
| Javelin | 15.9803 | 3.8 | 1.04 | metres |
| 800 m | 0.11193 | 254 | 1.88 | seconds |
Reference points
- 7291 — the world record, set by Jackie Joyner-Kersee (USA) in Seoul in 1988; it still stands.
- ~6500–6900 — the range that typically wins or medals at the Olympics and World Championships.
- 1000 points in a single event marks an elite benchmark: roughly 13.85 s in the hurdles, 1.82 m in the high jump, 17.06 m in the shot, 23.80 s in the 200 m, 6.48 m in the long jump, 57.2 m in the javelin, or 2:07.6 in the 800 m.
