Marathon

So my husband is training to do the Detroit Marathon and we finally convinced my dad to do it. He is one of the most incredible athletes I know and he still has yet to run one. He keeps making excuses that he is too old or something. So a few days ago he finally agreed. He didn't start official training yet but I just got a text from him saying something like, "just did a light 7 mile run. the cool air was so nice." Yeah dad, so old. My 50 something year old dad is not gonna have a problem.  Excited for my guys to do this.
