Boy you’re gonna be surprised o find out Tom Brady doesn’t represent every athlete. I also guarantee that when you are given USA gear that you wear it to bed and into the shower.
This is weird Instagram behaviour . This seems like an American thing.
To make money
Running is not really a sport. Fringe activity. The PGA is a sport, with this weeks Major working on 57 million dollar budget. TNT, Golf Channel have 225 production people on site and the track meet had delinquent kids asking questions on there web cast.
It’s not part of their job. No one is telling to pose for Instagram. It’s an ego thing. These people have nothing else going on in their lives besides running.
