What will happen if you ran in the rain?

Answer 1

nothing really, you would just get wet. The surfaces do become slightly slippier due to less friction but this usually isn't a major problem

Answer:

This problem is usually presented as "Do you get wetter if you run through the rain to get to your destination or walk?" and has confounded engineering students for years. The walk not run is wetter folks say you are in the rain longer and of courseyou get wetter. The run not walk folks insist that the runner not only gets wet from the rain falling but also sweeps out rain drops that never would have hit him if he walked and so of coursehe gets wetter.

The realist tends to feel that at some point in time you'll be as wet one way or the other.
