Experiments:
1.In your yard (or other large area) mark two points between which you can safely run.
2.Run at a steady pace from one point to the other while someone times your run
3.Run again at the same pace as before, but this time hold the open umbrella behind you. Have someone time how long the run takes with the umbrella.
4.Did the umbrella slow you down? Without the umbrella, the main drag was the air resistance against your body as you ran. With the umbrella open, it provided a much larger surface area that also had to be pulled through the air. This created additional drag, which meant that you had to work harder to run.
