Over 500 hundred of devoted athletes recently took to the waters of Ohio Street Beach to help prepare for the swim portion of the Chicago Triathlon, the nation’s oldest and largest triathlon, taking place on August 28, 2016. The swim portion of the race is deemed the toughest and most intimidating part of the Tri. At these clinics, coaches are on hand to walk participants through everything from how to put a wet suit on, how to safely enter the water, and how to avoid being kicked by another swimmer, among other things.
