The sprinter Jeneba Tarmoh is in Los Angeles, training to run in a relay in London, and still struggling to understand how a close race at the United States Olympic trials nearly three weeks ago became a national controversy and left her without a spot in the 100 meters at the Summer Games.

In the 100-meter final at the trials on June 23, Tarmoh was unofficially declared the third-place finisher ahead of her training partner and friend Allyson Felix — good for a spot on the Olympic team. But after a review of finish-line photos, race officials deemed it a dead heat for third place, leading to days of drama over which of the runners would earn the Olympic berth.

United States Track & Field officials gave Tarmoh and Felix options: One could cede the Olympic berth to the other, or they could break the tie with a coin toss or a runoff. Ultimately, Tarmoh ceded the spot.

Tarmoh and her agent, Kim Holland, said in telephone interviews this week that they remained dismayed by how the disputed finish was handled, though they said the situation had not adversely affected Tarmoh’s relationship with Felix or Bobby Kersee, who coaches both runners.
