CNN —Fiona O’Keeffe produced a stunning performance at the US Olympic Marathon Trials in Orlando on Saturday, smashing the previous record by more than three minutes. In her first-ever race over the 26.2-mile distance, O’Keeffe booked her spot at this year’s Paris Olympics as she crossed the line in 2:22:10, improving on Shalane Flanagan’s record of 2:25:38 set in 2012. Emily Sisson, the US women’s marathon record holder, and Dakotah Lindwurm finished in second and third respectively to complete the American women’s team for Paris. The 25-year-old became the youngest-ever winner of the women’s trials and the first woman to win the event on her marathon debut. “A lot of excitement, definitely some nerves kicking in,” O’Keeffe told reporters about her emotions on the final lap.
