Sprinters and distance runners are both runners, but almost everything about how they train and what their bodies do is different. One is built for short, maximal power; the other for sustained, efficient endurance. Here is how they compare and why their training looks nearly opposite.
Sprinting leans on fast-twitch muscle and the anaerobic energy system for short, maximal efforts. Distance running leans on slow-twitch muscle and the aerobic system for sustained work. Most athletes are stronger at one end, though training shifts the balance.
Sprinters do short, fast reps with long, full recovery plus serious strength and power work. Distance runners do high aerobic mileage with shorter recovery and threshold work. Doing too much of the other kind blunts your strength.
The 400 and 800 sit in the middle and borrow from both, which is why those runners train speed and endurance together. And every runner benefits from clean mechanics, whether the race is 100 meters or 5k.
