Finish Etiquitte

One thing I haven't seen discussed ... At the finish, if one has to run to the finish line on a beach/shore from the water, what is the etiquette on passing? i.e., person finishes swimming in front of me, but takes FOREVER getting out of the water to the finish line on the beach (walking slowly). Is it completely rude of me to run by him/her? -Would this differ between fun and more competitive races? -If the person was a different age group/sex, would that affect your approach? Thanks! (I'm new so if this is already discussed somewhere, please direct me.)
