    Whether you are racing or touring, long-distance cycling can be very rewarding. 1. In general, it is more important to prepare your mind and your gear (齿轮) for the challenge ahead than it is to train your body. The best way to physically train for a long cycling trip is to take a long cycling trip! There are several steps for you.

Stretch first! Warm up for at least ten minutes before each long-distance cycling session. 2. This way, you can reduce the risk of injury.

Pace yourself. 3. Try to keep up this pace as best you can. Use a lower gear so that you don't wear yourself out. Try to keep up a rate of roughly 90 rpm(revolutions［旋转］per minute) on a low gear to go easy on your muscles and lungs.

Shift gears. When you come to a hill, change into a lower gear so that you can more easily reach the top. 4. Throughout the ride, stay aware of how hard you are working. If you are struggling to push the pedals (踏板), you should switch into a lower gear to conserve your energy.

5. Even if you feel strong, stop every 10-20 miles to give your body a rest and ensure that everything is running smoothly. Rehydrate (补水) by drinking some water, and boost your energy levels with a quick snack. Keep doing so until you arrive at your destination.
