The current is a HUGE topic for the folks at Ironman Chattanooga. If this video below (shot by Crushing Iron personnel) is any indication, there will be PR Swims all over the course on Sunday . . . but, I have read Friday current (due to energy demands) is typically way stronger than the weekends. We shall see . . . and we will also soon know if a lot of racers will be making the questionable choice of wearing a wetsuit. For race updates on Sunday, follow me on Twitter @miketarrolly.
