Good Morning and Happy Holidays,
I would suspect the same thing motivates them that is motivating myself. Although I never broke 17:00 in a 5K, I still enjoy competing simply because I love to run and simply cant see my life without participating in the sport.
Lets be honest, even on this site, there are very few people who ever made it to the elite level. Yet, here we all are, posting about running and non running experiences.
Sometimes, it isn't about being at the top level. Perhaps there is much more joy in knowing you are performing your best and being around all the action in something you love.
