Olympic modern pentathlon competition format at Tokyo 2020
There will be 36 athletes competing in both the men's and women's events.
Modern pentathlon consists of five events: pistol shooting, épée fencing, 200m freestyle swimming, show jumping, and a 3200m cross-country run.
Fencing, swimming and show jumping are the first three events, and they are scored on points. The points will then be converted into a time handicap for the final challenge which is a combined event (pistol shooting and cross-country running).
The points leader gets to start first. The time advantage over his rivals depends on how many points behind the leader they were after the first three events.
The finish order of the run determines the medal winners.
As at previous Games the fencing part consists of two rounds, a traditional round-robin stage, plus a "bonus round".
The swimming portion will be scored based on time.
The athletes are then being asked to ride an unfamiliar horse over a show jumping course with 12 obstacles before the combined event determines the medals. .
Olympic Modern Pentathlon history
Modern Pentathlon is an event especially created for the Olympic Games by de Coubertin. It was first contested at the Games in 1912 and has been part of the program ever since. The pentathlon event in the Ancient Olympic Games, modelled after the skills of the ideal soldier at the time, served as inspiration for de Coubertin.
Originally, the competition took place over several days until a one-day format was adopted in 1996 in order to showcase in a more audience-friendly way.
Hungary's Andras Balczo remains the most decorated modern pentathlete in Olympic history with five medals. He competed at the 1960, 1968 and 1972 Olympics and took home three gold and two silver medals.
