Sprint 100m 200m 400m
- The race starts with a command: "on your mark" followed by "set" and then the gun is fired.
- The runners accelerate up to between the 40m and 60m marks, when they reach top speed.
- In the 200m races, runners only use 92 to 93 percent of their maximum speed.
- They reach their highest speed between the 100m and 150m marks.
- The time is registered when the runner's torso (chest) passes the finish line.
- That is the reason why most athletes lunge forward when they approach the finish line
- In the race, after the acceleration phase, it is important for the sprinters to run in as relaxed a mode as possible up to the 250-300m mark, when the lactid acid starts building up.
- From then on, the aim is to lose as little as possible.
- The best lanes are 3,4,5 and 6.
- The bends for the athletes in the inner lanes are tight while those in outer lanes can't see their competitors.
- The 400m is a lot about sprint endurance and the runners undergo a lot of lactic acid training in order to cope with the last 100m of the race.
