U.S. Olympic Legend Edwin Moses' Wife Files For Divorce

Here's a hurdle Edwin Moses is gonna have a tough time getting over ... his wife has filed for divorce and claims he's been cheating on her ... this according to documents obtained by TMZ Sports.

But Michelle Moses, his wife of 9 years, says the track and field star has been running around behind her back -- so, she filed divorce docs citing adultery and "cruel treatment."
