You don't need to participate in formal races to enjoy the ability to go fast and/or far. Even before Strava, people would "race" each other in group rides whenever a hill comes up, and themselves whenever they hit their standard loop. Plenty of non-racers have turbos to get them through winter, some of them use Zwift to make it a little less boring.
