Hit the Trail – 25% Off Women’s Solomon Trail Shoes + A Promo Code!: Trail running is one of my favorite outdoor activities. The varied terrain breaks up the monotony of running, and you have to be hyper-aware of your surroundings – one minute you might be hopping over a log, the next you might be splashing across a stream. It’s a good mental, as well as physical, workout! Trail running is also a great way to vary your workout and hit muscle groups that aren’t normally engaged with flat road running. You’re going to feel it after being out on the trails!
