You can also look at it this way as for as for "no monetary returns."Sean has a business coaching runners. It certainly helps his credibility as a coach to have an extensive and impressive resume.
Just as someone writing books. They will write a book and by using their running successes will try to sell those books. Otherwise, why list those credentials.
By not getting paid by the race or sponsors doesn't necessarily mean they aren't earning money from these accomplishments. It helps their business.
Now, if it were someone who doesn't earn their living from a running-related business then it would be for no monetary returns.
