Decathlon vs Heptathlon

The decathlon and heptathlon are track and field's multi-events, where the winner is decided by points across many disciplines instead of one. The decathlon is the men's ten-event competition; the heptathlon is the women's seven-event one, and both run over two days. That gender split is the historical norm, not an absolute rule anymore: World Athletics has begun keeping records for a women's decathlon too, though the heptathlon remains the championship event at the Olympics and World Championships. High school and college programs generally follow the same split, decathlon for men, heptathlon for women, and it's the format nearly every combined-events athlete grows up training toward. Neither event forgives a single bad performance the way a specialist meet can; a disaster in one discipline usually costs more than a personal best elsewhere can make back. Here is the full event order for both, how the scoring compares, and who actually competes in which.
