Your surface area doesn’t decrease from you having a higher speed. In fact, because humans are quite vertical objects, moving them fast along the horizontal axis means they actually have a somewhat higher chance of crossing paths with something dropping vertically.
This is the same for rain, by the way. But since moving at a higher speed typically means you get to your destination sooner and spend less time outside of a house, it’s still generally a good idea to go fast.
