“When you're in a funk
Almost every competitive runner I know goes through a period when he or she feels like quitting. I certainly include myself in that category. What's ironic is that the tools that help make an elite athlete - focus, effort, attention to the latest technology - definitely do not provide the answer to getting out of a funk. I find the best way to get your running mojo back is to lose the technology, forget the results, and run free. And forget that running needs to be painful or that it's punishment. (Definitely get rid of those echoes of countless coaches ordering you to "take a lap" because you dropped a pass or double-dribbled.) Run for the same reason you ran as a child - for enjoyment. Take your watch off. Run in your jeans Run with a dog (does he seem worried?) Run with someone older or younger, and you'll see running, and the world, differently. I know I have.
Run a trail you have never run before. Pick a new goal, race, or a large loop that keeps you motivated to get out on those bad-weather days. Do all and any of these thing often enough, and you'll remember why you started running in the first place - it's fun.
