This isn't a big deal, and just a technicality, but I was actually wondering a few times when watching post-race interviews.
In your opinion, when are you officially an "Olympian"?
Is it 1.) after qualifying; or 2.) after actually participating in the Olympic Games?
As an example, if a qualifier didn't participate in London for whatever reason (injury, boycott, etc...), are they still an Olympian?
(please don't be clever and say yes for Meb, Abdi, Ryan, etc.. just since they already participated in prior Games).
