The special thing being given to those running the race is the privilege of running the race. I understand that it is a way for time qualifier entrants to distinguish themselves from charity runners, but that can also be done through bib # and corral and a variety of other means.
Look. It's a free country, and companies can sell whatever they want. But I am also free to point out when they are needlessly being douchebags and when a toxic running culture gleefully aids and abets this sort of behavior.
Alienating 11,000+ runners who worked hard to meet the BQ standard is completely unnecessary. Why not call it a "Boston 2023" singlet with roman numerals, like they sell for the other World Majors? Calling it a "BQ" singlet and then excluding 1/3 of the qualifiers this year (the 11,000 out of the 33,000+ who ran BQs) is what is colloquially referred to as a "dick move," and no amount of ad hominem attacks, browbeating or other BS will dissuade me from this fact, sorry.
I speak for the 11,000+ voiceless BQ runners, that 34 year old guy with a 2:54:35 who is being told he can't run (to make room for the thousands of charity and invitational entries and other time qualifiers with far more generous standards), and is now being told by Tracksmith "not that you wanted it, but just in case you were curious, you can't even buy a singlet with BQ '24 printed on it - this race isn't for joggers."
The running community needs to seriously self-examine.
