How many meters is the most suitable for running every day?

This depends on your physique, and it needs to be done step by step, not too much at once. You can jog 50 meters on the first day. Gradually add a lot and accelerate at a constant speed, if only to enhance physical fitness. Running 1000 meters a day is enough to achieve the effect you want. The most important thing is persistence. If you want to practice long-distance running, add more. But don't overdo it. Just under 5000. Unless you want to be a professional in this sport.
