What is the first event in an Olympic heptathlon?

The women’s heptathlon rules are exactly the same as the men’s decathlon rules, except that the heptathlon consists of seven events, also held on two consecutive days. The first day’s events, in order, are the 100-meter hurdles, high jump, shot put and the 200-meter sprint. Second-day events, also in order, are the long jump, the javelin throw, and the 800-meter run.

The 100-meter hurdles is the first event of the heptathlon. The women’s race is run on a straight track and the runners must remain in their lanes.

The rules for each event within the heptathlon are generally the same as for the individual events themselves, with a few exceptions. Most notably, runners are allowed two false starts instead of one, while competitors receive only three attempts in throwing and jumping events. Competitors cannot pass on any event. Failing to attempt any single event results in disqualification.
