Distance runner Kara Goucher qualified for a second event at the US Olympic trials in Oregon on Friday, but her joy was tinged with sadness after her husband failed to join her in the squad for next month's Beijing Games.

The 10,000 metres world bronze medallist had already booked her spot in the US squad at that event and she will double up in the Chinese capital after clocking 15:01.02 in the 5,000 metres to claim her first national title.

"Winning that was a huge accomplishment for me and it was really awesome but right now I'm really sad," a tearful Goucher told reporters after watching husband Adam fail to make the 10,000 metres team.

He finished a non-qualifying seventh after successfully petitioning to enter the event ahead of seven faster runners.

Somalian-born Abdi Abdirahman won in 27:41.89 with Oregon collegian Galen Rupp second in 27:43.11. The third and final spot went to Jorge Torres in 27:46.33.

Adam Goucher was another 13 seconds back in 27:59.31 but was never a contender. He declined comment after the race.

His wife stayed among the leaders throughout the 5,000, then sprinted into the lead in the final bend.

Jen Rhines finished second in 15:02.02 with 10,000 metres trials winner Shalane Flanagan also set to double up in Beijing after taking the third and final berth in 15:02.81.
