Too good to walk?? Think again. Here’s some new literature demonstrating you can build strength and improve your running with walking breaks. One of my better times in the marathon came when I trained using walk breaks on my long runs.
It’s just one of those rules. Coaches, runners, and pretty much everyone else involved in the sport have traditionally emphasized that walking isn’t an option there. But new research and training methods indicate that walking may not be a sign of weakness, but a tool for becoming an even stronger runner.
