IF YOU RAN WITHOUT SACRIFICE, CONGRATULATIONS. YOU JUST JOGGED. Running hurts. It always has... It teaches us that good things do not come easy. It teaches us that hard work will be rewarded and laziness will be punished. Don't expect to learn those life lessons from running's shiftless stepchild; jogging. Next time you suffer on the roads or trails, suffer proudly. It means you run like an animal.
