I never ran a 10K run, even though I had thought about it and aimed at it. It was not indeed me. It becomes too boring for me to run. Although right now my only exercise is a 2.3Km walk/run every other night that takes me about 20 minutes to finish. In addition to a healthy exercise, it is a mean to depressurize the day.
Yesterday, however, M ran a 5K in 25 minutes and 27 seconds and broke his own record of 27 minutes. He just started running about two months ago. I am proud of him!
