1. Ditch the pavement.
The trail I normally run on is an asphalt bike/walking trail that winds through my city for several miles. I love the convenience of it, but I’ve learned that you have to mix it up. Running on pavement all the time is going to kill your legs and knees (my dad actually had to have hip surgery after years of being a pavement runner). So I’ve also been hitting up a local hiking trail that’s completely dirt. Bonus? It has hills that force me to train harder.
