According to The World Athletics Council press release, it has approved an innovation to the regular competition format for the Paris 2024 Olympic Games, introducing a repechage round to all individual track events from 200m to 1500m in distance, including the hurdles events.
In the new repechage format, athletes who do not qualify by place in round one heats will have a second chance to qualify for the semi-finals by participating in repechage heats.
This will replace the former system of athletes advancing through the fastest times (q) in addition to the top placings in the first round heats (Q).
These events will now have four rounds – round one, repechage round, semi-finals, and the final, with schedules varying according to the specific nature of the event.
The new format means that every athlete competing in the events with a repechage round will have at least two races at the Olympic Games.
As the 100m already has preliminary heats, before round one, the repechage will not be introduced in this event. In addition, the repechage will not be introduced in distance events as the need for proper recovery between rounds makes the format impractical.
The final regulations of the format, including the timetable as well as a system of advancement in each event, will be announced well in advance of the Olympic Games.
