3．What is cross country running？Cross country is an outdoor endurance（耐久性）sport that can be mentally challenging and fun.（1）
You're not only putting one foot in front of the other；you're also thinking ahead to barriers and changes in the trail or course.
（2）However，before you begin training and racing，you should be aware of potential injuries and how to avoid them.How can you prevent cross country running injuries？The best ways for outdoor runners to stay healthy include the following running tips：
Stretch daily.For all runners and athletes，a regular stretching routine is an important part of conditioning.（3）
Warm up and cool down.Muscles and tendons（跟腱）are less likely to overstretch or tear if they've been properly prepared for running and racing.High-intensity workouts require more prep and post-workout cool down than low-impact activities.
Wear the right shoes.Make sure your shoes fit properly and that they are neither too tight-fitting nor too loose.（4）
Eat and drink enough.Competitive distance runners like to keep their weight low.However，consuming too few calories can harm your body，especially if you're a girl or woman subject to eating disorders.（5）It's effective to prevent injury and heat illness.Remember that especially in full sun or in humid regions of the state，you particularly tend to have heat stroke.Drink plenty of water before and after running.
A.Cross country running is a sport requiring money.
B.Tie double-knots to prevent tripping over undone laces.
C.It's mostly very safe in comparison to other team sports.
D.Have a well-balanced diet and be sure to stay well-hydrated.
E.You may encounter unexpected，non-natural barriers.
F.It is needed to keep your bones，joints，and muscles healthy.
