Jess McClain was leading the U.S. Half Marathon Championships in Atlanta when she was mistakenly led off course by the lead bike, leading her to ninth place and leading Emma Grace Hurley and Ednah Kurgat back on course. The error cost McClain a significant lead and cost her a $20,000 prize. The win would have been McClain's first national championship and would have qualified her for the world championships. However, the USATF ruled that there is no recourse to alter the results order of finish. The Atlanta Track Club CEO, Rich Kenah, took responsibility for the mistake, stating that a pace vehicle left the official course during Mile 11.
