Our love-hate relationship with running

How often do you have to push yourself to do something you know will do you good, even when it feels like a struggle?That’s what running is like. Even if you enjoy it, it can be uncomfortable – aching legs, burning lungs, and that nagging voice in your head telling you to walk the rest of the way.So many of us have an on-again, off-again relationship with running – and yet we keep coming back. Run clubs are booming, marathons are selling out, and more people are lacing up than ever before.So what is it about running that keeps us hooked – and what else might be drawing us in?
