On August 17th, an Olympic-length Triathlon will be run in the heart of Indianapolis, just in time for this year's Olympic games in China. And while it may not be anything new for local organizers to create an event for the fitness and fun of residents, this event will have an interesting twist:

A leg of the event will involve athletes taking a swim in the canal downtown.

Swimming isn't normally allowed, and the idea has some people wondering if the artificial waterway is safe for exposure. But city officials and the event's organizers have tested and prepped the water to make sure it's extra safe.
