Constantly changing the route of running training is a good way not only to get rid of routine, but also to reduce the risk of injury. This fact has long been known, but almost no one takes it into account.
Running the same route every day can decrease a runner’s concentration, just as a driver loses alertness when the monotonous environment does not change throughout the entire road. For novice runners, this relaxation often results in a loss of control over running technique.
However, the most important fact for runners who train for results is that monotonous training is very bad for improving performance. Even if your route includes all kinds of surfaces and big differences in altitude, but the route does not change for a long time, the body, the brain and the nervous system easily adapt to it. In this case, the body loses the impetus for further progression.
Of course, you can constantly change the pace and break your records in certain sections. But, as practice shows, a much more effective option is the usual change of direction on the next run. As well as periodic training with an unpredictable route, terrain and distance.
