EUGENE, Ore. — Jeneba Tarmoh changed her mind after listening to her heart.

Choosing inner peace over a shot at Olympic glory, the 22-year-old sprinter withdrew from a runoff for the final Olympic spot in the 100 meters, deciding to concede it rather than meet training partner Allyson Felix at the starting line to break a third-place tie.

With that, the U.S. track trials were over. The final spot determined before the race was run.

Tarmoh notified USA Track and Field early in the day of her intention to withdraw from the Monday night race. Her heart, she explained, wasn’t into competing again.

Not after already securing what she thought was the third spot in the event at the trials on June 23.

In that race, Tarmoh crossed the finish line and looked up to see her name on the scoreboard in the third spot behind winner Carmelita Jeter and runner-up Tianna Madison. And then came all the rewards of making the Olympic team — a celebratory lap around the track and a medal.
