Is stretching necessary when I run?

Stretching is beneficial to runners when done properly. It also reduces muscle soreness after running and results in better athletic performance, along with reducing lactic acid buildup after a workout. Whatever you do, take your time and stretch in a manner that is comfortable for you. Improper stretching remains the second leading cause of running injuries, which is why I wrote “The Runner’s Guide to Healthy Feet and Ankles” and includes the do’s and don’ts of stretching.
