let me explain my situation so my question will make sense. ive been on a health kick for almost a year, watching what i eat, hitting the gym, and riding my bike when there isn't 22in of snow on the ground (that was just the last snow fall) when im at the gym on the treadmill i am able to run a 5mph pace for 1/2 hour with no issue. but if im out side running on a path or down the streets i have a very hard time running the same speed for the same distance. using music with a beat dose seem to help but i still struggle. so what helps you and what can you recommend.
