When he first arrived at the U.S. Olympic Track & Field Trials, Trevor Dunbar of Kodiak, Alaska wasn't even sure he would get a chance to compete.
After Monday's performance, he is one great race away from making the London Games.
Dunbar, who qualified for the trials on a provisional basis, was allowed in the field on Saturday when a couple of runners with faster times backed out.
In Monday's preliminary race, he finished third in his heat to qualify for Thursday's final in a time of 13 minutes, 49.19 seconds. The top six in each heat plus the next four best times advance to the 16-man final, and Dunbar erased any doubt by passing three runners on the final lap.
Dunbar's time was the 11th fastest in both preliminary heats combined. The three fastest men in Thursday's final grab a spot to the Olympics.
Dunbar attends and runs track for the University of Oregon, where the U.S. Trials are being held.
