If you've ever tried running alone, you know it can be difficult to get the motivation to go out and exercise. It's easy to come up with an excuse not to go -- maybe the temperature outside isn't right or the food you ate last night is disagreeing with you. Running is typically viewed as a solitary sport, but there are large groups of fitness-minded people out there.
Running clubs are exactly what they sound like: organizations for people interested in running. Each city has different rules and activities, but they're all bound together by the idea that a community is stronger than an individual.
