to kill time means that you're doing something while you're waiting for something. Are you sure that you go running when you're waiting for something else to happen? 

I Love Running

At first I ran to stsy fit and kill time. I ran l every night at the school playground. Then I started listenjng to music while I was running. It encouraged me to keep running for a long time and I gradually realized that running  is not just a boring sport. When I'm running, I can enjoy being in the moment with my regular breath. The feeling is really great after you have finished a long run. I started joining  running groups and contests like half marathons in my free time.. I realized that there are many people in Taiwan who are intent on running. Running with lots of people who love running is very enjoyable. Anyway, those are the reasons I love running. Feel free to join me anytime.
