Mayor Rahm Emanuel's morning workout may be in jeopardy.
The mayor revealed during an unrelated news conference Friday that he hurt his ankle during a run home from his morning swim, according to The Sun Times.
Besides getting in the way of his daily exercise routine, the injury could hurt his chances at the triathlon he's been training for.
Last month, Mayor Emanuel revealed his workout routine with CNN's Wolf Blitzer.
The mayor told Blitzer he works out seven days a week, swimming one mile three days a week and riding a bike 25 miles each Saturday.
