As a runner you’re going to find yourself at a crossroad. Should you work up a sweat outside or do you pay your local gym a visit and run on their treadmill for 30 minutes? This is a question that many runners face and while some may think that both are exactly the same, there are clear differences and advantages to outdoor and indoor running.

Cardio can be boring. We get it. There is nothing more uninteresting than running on a treadmill or completing 30 minutes on an elliptical machine five times a week. That’s why it is good to find aerobic training activities that are not so repetitive.
