同时我还参加了一些短距离的比赛，这给铁人赛的艰苦训练带来了乐趣。

I also am doing short RACES, which is fun after the strenuous training for Ironman.

对于马拉松而言长距离跑通常是指16英里或更长的距离，对于其他一些短距离的比赛，更短的距离也算是长距离跑。

For marathons, a long run is usually considered 16 or more miles, but for people training for shorter RACES, shorter runs can still be considered long runs.

如果你是游短距离冲刺自由泳的，那么你一定清楚大多数比赛都是在百分之几秒间分出胜负的。

If you are a sprint freestyler, you know that most RACES are won by hundredth of a second.
