I’m running the NYC Half Marathon in a few weeks under a charity. The race has 20,000+ runners but sells out pretty quickly and once it’s sold out the other way to gain entry is through fundraising for a charity. I chose a charity I’m genuinely passionate about and hit my fundraising goal. The charity mailed out some shirts with the name of the charity and the charity team. While I really like the shirt, it’s a bit large for me and not something I’ve run enough in to know how it will feel in a race or effect me with things like chafing. I usually wear the same set of clothes for races because I’m accustomed to running in them and I’m trying to run a competitive time to potentially qualify for the NYC Marathon. WIBTA if I didn’t wear the shirt?
