Move with a Puropse

Game idea: run for a certain interval. The end of the interval is determined by some change in circumstance that the runner chooses. Things such as terrain change, runner exhaustion, runner thought, time frame (for faster sprinting, no more than 30 seconds), etc. At the end of an interval or transition, the runner changes pace. They can walk slowly or quickly, or trot very slowly, or move at whatever pace in whatever style they wish. 

The game is that the reason they create for their new way of moving... I had this better in my mind the other day while running. Suddenly I'd be running slowly because I heard a bird sound, and so I would listen to birds. Or I ran fast again because the terrain had interesting roots to jump over, and I would be running fast again. There is a justification or an explanation somewhere in this that is interesting, and can lead to fantastica thinking and fantastical movement.

Rethinking it: you run, or walk, or rather change pace, with an emotion or a feeling. Think of that feeling. Run with it deeply, walk with it deeply, have it affect your movements in a deep way. Then figure out how to remember why, and then instruct the other players on that feeling and that they should run with it. 

(Really needing to refine this idea, but there is something to noticing the emotion you're running with and somehow grabbing onto it to share with the group, so that they can run with it and see what it is like.)
