High-grade athletes, the first lap and the second lap time difference is 2-3 seconds. At this time the slowest is often the second 200 meters, or the third 200 meters. The difference between the first 400 meters for the best athlete and the second 400 meters is 1 second. The slowest part is usually the second 200 meters or the third 200 meters. 1500 meters run. Low-grade athletes running speed, each lap (400 meters) lower 2-3 seconds. The last 300 meters running speed is equivalent to the third lap speed. High-grade athletes, the first 400 meters faster than the second and third 400 meters 1-3 seconds, the last 300 meters running speed equivalent to the first lap level, or slightly faster. Outstanding athletes, the average speed of the first three laps is almost equal to the speed of the last 300 meters.
