A very hot day for racing at the Racine half ironman distance race pushed athletes to their limits on a run course that featured a heat index of nearly 100 degrees. Overall, the average finish time was 6:09, and while the bike split average of 2:58 was speedy, the heat slowed runners to a 2:21 average.
Evidence of the heat's impact resulted in a 7% DNF rate and a higher than normal number of triathletes who rode too hard and suffered on the run (upper left quadrant).
