If you want to breathe crisp and clean fresh air with unrestrained lungs you need to be spending time out in the open during the winter months. Reconnect with nature while running for maximum mental health, cardiovascular and strength benefits. Jogging throughout the city or in the gym can get very boring after a few miles. This is where trails come in. Change your running environment and make it more fun and challenging by swapping out hard asphalt for softer ground, even if that’s snow.
