Event Jersey ettiqette

[7rider]

As an ex marathoner the runner etiquette is that you don't wear the event shirt on the day of the run because you haven't earned it yet. Is it the same for cyclists? or do you expect to wear the event jersey on event day?

Geez. I just signed up for my first ever 5k, hosted by my Fitness Center. Admission comes with a t-shirt, which I was specifically told would be in just prior to the event, so I could wear it day-of, if I wanted to.

Huh.

Most bike rides that have jerseys, it's common to wear them day of. Some would argue it's tacky to wear dated jersey AFTER the event on other rides.....
