Kieffer Pulls Out of Olympic Trials

Olympic hopeful and made the painful decision Friday to abstain from competing in the U.S. Olympic Trials, citing a right calf injury and left hip tightness.

Kieffer called the decision to pull out "heartbreaking," in a blog posted on her website Friday afternoon. She was set to run the 10K in the trials at 10:20 p.m. tonight in Eugene, Or.

The 24-year-old pro runner, who stood out as a track star during her days at West Islip High School, has struggled recently due to her injuries, but was hoping for the best in the trials.

"After spending an hour and a half in the medical tent yesterday it was pretty obvious that I’m not crazy, my body isn’t moving correctly or efficiently," Kieffer wrote on her site. "Ultimately I let my coach make the final call. My willingness to, and the possibility of, breaking a bone to place top 6 at the Olympic Trials didn’t sit well with him. That made it painfully clear – no racing tonight."

Despite her disappointment, Kieffer seemed optimistic about the future and wished her fellow racers well.

"Now it’s time to rest, recover, and rejuvenate with the love of friends and family. Good luck to all racing!" she wrote.
