Wikipedia explains running as a means of terrestrial locomotion allowing humans and other animals to move rapidly on foot and is described as the most accessible sport in the world. This is the beauty of this sport that you can run on just about any surface and take it up at any age. Runners live by discipline and hold no exception - on where to run. Changing different running surfaces is beneficial for your body conditioning, improves your performance, eliminates boredom and is good for mind too.
However, not to forget that running is a high impact sport and not all surfaces are created equal. Due to the uneven surfaces, ranging from harder to softer surfaces; it involves different impact and stresses on the body which make their way up to the joints. There is no harm in varying surfaces as long as harder surfaces like concrete are rarely used. Switching surfaces teaches the body to adapt and avoid injuries due to repetition. Your shins, calves, hips, knees will all thank you together if you keep variations in your training plan.
Below are the comparisons drawn between different running surfaces explaining their properties:
Regardless of where you run daily, break the regular routine pattern, and explore the places, switch the surfaces, add more miles while you train yourself to be a better and injury free yourself. Isn’t that fun!
