Well, many people do care. You don't have to be elite to want to run faster. Keep in mind there seems to be no good reason to exercise more than 30 min 3-4 times a week, but many runners choose to do a lot more than that. For that matter, there's no good reason for most of the things people buy or time they spend on the hobbies and other leisure activities they pursue. I can assure you, they will not need to focus their marketing efforts on convincing people to care about going faster. A great number of amateur runners already do. (Not all, different runners are motivated by different things.)
