要提高中长跑的成绩，教练员要注意加强对运动员的步长训练、摆臂训练、速度耐力训练、心理素质训练和成绩测试工作。

The coach should attach importance to the training of pace length, arm swing, speed and stamina as well as psychological quality in order to improve their performance.

这个阶段强调轻松的耐力跑，但是记住不要把基础训练和健康跑混淆起来，你是通过增加你跑步的距离以及作一些速度和力量练习来打基础。

This phase emphasizes easy miles, but don't confuse base training with fitness running. You are building a base by increasing miles and adding some speed and strength work.

幸运的是，你可以两者都拥有。你可以按照增加长跑距离的计划进行训练，也可以按照提高速度耐力的计划来训练。

Fortunately, you can have it both ways. You can follow training plans that build the length of your long runs, and others that improve your speed-endurance.
