I recently wrote about the Canadian triathlete Julie Miller, who was disqualified from the Ironman Canada race last summer and stripped of her first-place finish in her age group. Officials said it would have been impossible for her to complete the course as quickly as she claimed.
Other athletes suspected her of cutting the course, possibly by failing to complete one of the laps in the two-lap marathon, but no one could prove how she did it. Among other things, Miller finished the race without her timing chip, meaning that there was no information about her split times — interim times reflecting an athlete’s progress along the course.
