Why would Sam quit professional running to suddenly join the army? Doesn’t make much sense to me as he is one of the top US runners and has a good chance at Olympic qualification in 2020.
Is he a full US citizen? I know he lost his sponsorship with Nike, could this be something to make money as he might not have enough?
Just seems odd that someone would want to leave pro running to join the military.
He's 33 and he's not suddenly joining the army, he joined it years ago
