They are in nature. They are both sports that can be engaged in by one person. Unlike ball games, there is a definite victory or defeat. Except for the time gap in professional competitions, the two are just different carriers. You need a decent pool more than swimming, and running just needs a so-so road. Under the epidemic, it seems to be the best and only option for exercise. Swimming and running are also relatively suitable sports for loners, and there is no need to drag around and call friends. Since the isolation at home, I have been in a state of "don't approach strangers" for several days or even weeks.
At work, except for necessary meetings, I basically stare at the computer screen and murmur. It seems to have gotten used to it unconsciously, or had photo color correction services to learn to live with loneliness. After I started working from home, no colleagues around me used "See you tomorrow" to remind me that it was time to get off work. With the extension of the sunshine time, it is often seven or eight o'clock in the evening. I had to do something to remind myself that it was time to get off work, so I started running. It's about a year since I moved to Silicon Valley, but I'm ashamed to say that I may have only visited the park three minutes away from my house.
If you were talking about the number of walks around the house, the answer would probably be never, let alone running. In California, no car is equivalent to no feet, and people who are used to driving have forgotten the original purpose of their feet. Fastening my shoelaces, I took the first step, followed by the second and third steps. The rhythm of running often depends on the two or three steps taken at the start. Too slow or too fast will not work, it is best to maintain At a speed of "slightly faster but still able to catch your breath".
