That bum ankle Mayor Rahm Emanuel complained about last month didn't end up keeping him out of Sunday's Life Time Triathlon.
The mayor was among the successful finishers, completing the race in one hour and 36 minutes. Of the 80 participants in Emanuel's age group, he came in ninth.
Emanuel has been an avid swimmer and biker but had said running was his weakness. Earlier in the summer he said he hit the sidewalk wrong while running and injured his ankle.
Around 10,000 people were expected to participate in the event. The National Weather Service had issued some choppy water warnings on Sunday for boaters and swimmers.
Triathlon officials said no injuries were reported.
The Life Time Chicago Triathlon serves as the fifth of seven events in the 2011 Race to the Toyota Cup. Participants in the weekend's events included former Olympians, professionals, physically challenged, service members, elite amateurs and first-time participants from 46 states and 19 international countries.
