Sprint races are among the most watched events at the Olympics and World Championships. The 100m, 200m and 400m are decided by tiny margins, so the rules are strict and precise. Here is a simple guide based on the competition rules of World Athletics.
The sprint events
- 100m: run on the straight.
- 200m: half a lap, starting on the bend.
- 400m: one full lap.
- Hurdles and relays also follow sprint start rules.
The start
All sprints up to 400m use starting blocks and a crouch start. The starter gives two commands in English or the local language:
- On your marks: athletes settle in the blocks with hands behind the line.
- Set: athletes raise their hips and hold still.
Then the gun is fired. Athletes must not move before the gun.
The false start rule
Since 2010, World Athletics has used a strict rule: an athlete who makes a false start is disqualified straight away. There is no second chance, except in combined events like the decathlon.
Starting blocks are fitted with sensors. If an athlete reacts in less than 0.100 seconds after the gun, it counts as a false start, because research shows humans cannot genuinely react faster than that.

Lanes
- In the 100m, 200m and 400m, each athlete must stay in their own lane for the whole race.
- Stepping on or inside the lane line on the bend can lead to disqualification.
- Lane draws in later rounds depend on performance in earlier rounds.
The finish
The race ends when any part of the athlete’s torso, not the head, arms or legs, crosses the finish line. A photo finish camera records times to a thousandth of a second, and results are announced to a hundredth of a second.
Wind limit for records
For the 100m, 200m and the sprint hurdles, a following wind of more than 2.0 metres per second makes a time ineligible for records. Such times are marked as wind assisted.
World records
- Men’s 100m: 9.58 seconds by Usain Bolt of Jamaica, set in Berlin in 2009.
- Women’s 100m: 10.49 seconds by Florence Griffith Joyner of the United States, set in 1988.
Sprinting in India
The Athletics Federation of India runs national events, and the Sports Authority of India supports athletes through training centres and schemes like the Khelo India programme and TOPS.
Bottom line
A sprint is decided in seconds, but the rules behind it are detailed. One false start, a step outside the lane or too much wind can change everything.
