Chicago's plans for the 2016 Olympics include a Marathon venue situated in front of the Buckingham Fountain.
Organizers of Chicago's 2016 Summer Olympics bid say they have an ambitious plan to put on an environmentally friendly event if they win the chance to host the Games.
Chicago 2016 spokesman Patrick Sandusky says there's a great opportunity to showcase the city's parks and lakefront. Organizers tout a low-carbon event that has most sport venues along Lake Michigan.
Vehicles provided by the Games would run on low-carbon fuels or electricity, and venues would run on 100 percent renewable energy. Stormwater would be collected for reuse, and the event would use recyclable or reusable products.
The sites themselves would be built to green building standards.
Madrid, Rio De Janeiro and Tokyo also are bidding for the games.
The International Olympic Committee will choose the host city in October.
