The first question you get asked after a race? Your time. But is that the only reason you are there? To PB?

A personal best may offer some immediate gratification but in the quest for happiness and more consistent motivation is it worth reassessing why you were there in the first place? Runners in particular are heavily target driven but we should make a distinction between onward progress and staying restless vs. winding up perpetually dissatisfied. 

Ask yourself how was the atmosphere, competitors and spectators? Did you travel somewhere new or try something different? Did you learn something about yourself? Did you forget the stress of work? Were you inspired by your team mates or fellow athletes? 

Did you inspire somebody? 

Almost certainly yes.
