Actually ran quite many, these two times has the representative point. I generally do not run a lot, although from junior high school has been running, but I think a one-time exercise is too large, harmful to people. I haven't had more than 15km of a single run so far.
--Two days ago just heard that Xiamen half marathon (21.3 km or so) someone at the end of 4.5 kilometers away, and reached the end, respectively, the sudden death (a total of two places. )。 Therefore, everybody likes the movement to be good, must in the own right and for. Be sure to remember: extremes meet.
Marathon 42 km down, it needs to be very well prepared to do. In addition to mental preparation, but also let oneself can not speak of the body also adapt, ready to do. If the conditions are really not there, do not reluctantly.
This is from the running app's point of view I ran the fastest 10km:
This is the most interesting way for me to run the path:
Running apps are not accurate. This not only has the hardware aspect the factor, the software and the algorithm factor also has. Of course, the factors of the objective use condition also exist. --just use the app for entertainment and timing (the most common watch for timing is accurate) and don't create app dependencies. So far, no reliable running app has been found.
The above roadmap, in fact, is far too much of an error, even considering the various possible suggestions made by app developers. In particular, the second, two of the line between the playground, not only a busy road car to the car, there are a lot of walls and buildings, run into such lines, must also have yellow pharmacists and Zhou Botong like the Qinggong.
The ancients said that the letter is not as good as books, the app is more unreliable than the "book" is much more. Don't be encouraged by app advocates to do things that are more than you can do. Take advantage of them and not be used by them.
