The reason why you get wetter when you're running, is due to you hitting more droplets of water as you run. Imagine you're sitting in a train that's standing still while it's raining. You'd see the water falling straight down. Once the train starts moving, you'd notice that the water seems to fall towards the side, diagonally down. The faster the train moves, the more the angle would increase until the rain seems to come from directly in front. What this boils down to is that droplets that would have missed you, had you been standing still, is not hitting you from the front, simply due to you running, and you end up getting wetter.
