400 meters Race
- Track
- Sprints
The 400 metres is the longest sprint event in track and field, often referred to as the “long sprint” or “speed endurance” race. It demands both raw speed and exceptional stamina as athletes complete one full lap of the track at near-maximum effort.
This race tests a sprinter’s ability to pace strategically, endure lactic acid buildup, and maintain strong form and speed through the final stretch.
Key Demands and Challenges:
-
Effective energy distribution across all race phases.
-
High lactic acid tolerance and muscular endurance.
-
Maintaining sprinting form under physical stress.
-
Strong mental focus to follow the race plan and finish strong.
Basic laws:
-
The race covers a distance of 400 metres (one complete lap).
-
Athletes start from staggered positions and must stay in their assigned lane for the entire race.
-
An electronic start system is used; a start before 0.1 seconds is a false start and leads to disqualification.
-
Lane violations (leaving or stepping outside the lane) result in disqualification.
