Nike is announcing today that it recognizes Arien O'Connell as a winner in last weekend's Nike Women's Marathon with the fastest chip time, completing the full race in 2:55:11. She shattered her previous time and achieved an amazing accomplishment.

Arien will receive the same recognition and prize, including a Tiffany & Co. bowl, the full marathon elite group winner received. Arien was unfortunately not immediately recognized as a race winner because she did not start the race with the elite running group, which is required by USATF standards. Because of their earlier start time, the runners in the elite group had no knowledge of the outstanding race Arien was running and could not adjust their strategies accordingly.

Learning from the unique experience in this year's race, Nike has decided today to eliminate the elite running group from future Nike Women's Marathons. Next year, all runners will run in the same group and all will be eligible to win.

Nike has a proven track record of supporting athletes and we're proud to be able to honor Arien and other athletes who surpass their goals and achieve great accomplishments.
