1. My running history:

I just loved to run when I was in college. After graduated, I kept running now and then. This habit was totally stopped after I entered a graduate school in China.

Then, I went to a US school. It was after I found my first job that I resumed my running hobby. Since then, I have been running for years.

2. Lunch Break:

Every one has one hour for lunch break at my working company.  In our lab facility, there is a loop track for vehicle testing, I was told that the distance for a whole loop is about one mile. I used to run at home during night time, started from last year, after I saw two of my co-workers running along the track, I joined them and we formed a 3-person lunch break running team. Typically, we run two or three times a week.
