First, many people in fun run are mostly office workers or have requirements for their bodies. They think the gym is too expensive, but they have to go to work during the day and have no time, so they will choose to run after work. Some people who want to lose weight will choose not to eat and run, but in fact, people's blood sugar is generally low on an empty stomach, and running is a big exercise that consumes a lot of fat and physical strength. Running on an empty stomach can easily cause weakness and dizziness in human limbs.

Second, some interesting runners are unprofessional. They run whenever they want, and they often have leg cramps when they run. This is because they don't warm up before running, and they cramp after running for a while.

Third: People in fun run should pay special attention not to wear dark clothes because of the light at night. It is best to wear fluorescent or bright clothes or carry small lights with you, so that other people's cars won't come and cause accidents when running in the countryside or city streets at night.

Fourth: Like my former school team came out to run sprints, I know that during the competition, people can run faster than the whole sole with their toes on the ground, but fun running is not a competition. Many people will choose to touch the ground with their toes first, which will easily thicken your calves. If you want to lose weight, you should be careful not to run like this.

Fifth: fun run Many girls will run alone, but in fact, it is suggested that fun run should pay attention to the best companionship, or bring tools to prevent wolves with him. After all, you should always take precautions when you run to a desolate place at night.
