American Dathan Ritzenhein can be seen in third place.

Finishing third behind 5,000/10,000 Olympic and world champ Keninisa Bekele of Ethiopia (12 minutes, 52.32 seconds), Ritzenhein's time of 12:56.27 broke the 13-year-old mark of 12:58.21 by Bob Kennedy.

Ritzenhein, coming off a sixth-place finish in the 10,000 in a personal-best 27:22.28 at the world championships in Berlin, had run a 5,000 best of 13:34.00 this year and a best-ever of 13:16.06 in '06.

"I was thinking he'd run in the 13:05 range," said Alberto Salazar, Ritzenhein's coach, who watched the race at Nike headquarters in Beaverton, Ore. "With his workouts and what he'd done in Berlin, I thought he was ready for a big PR (personal record). I'd be a liar to say I thought he was going to break the American record."

For much of the early going Friday, Ritzenhein was in last place. He had been warned by Salazar that the front-runners were shooting for a record 12:45 pace. In a Thursday phone call, Salazar said he told Ritzenhein to not to lose contact with the runner ahead of him.

Salazar told John Capriotti, Nike's head of track and field, who was in Zurich, "He might be in last but he ain't going to stay in last."

As runners ahead of him began to fade under the scorching pace, Ritzenhein started passing people. With 800 meters to go, he needed to run 2:03 for the final two laps to crack 13 minutes.

"With three or four laps left, he started blowing by people," Salazar said. "He has this unbelievable ability to grind by himself like that."

Ritzenhein reached second at one point, but was passed with about 150 meters left.

He became the fourth non-African to break 13:00 behind Kennedy, Germany's Dieter Baumann (12:54.70) and Australia's Craig Mottram (12:55.76).

"What Dathan did today validates what everyone in this country has been trying to do — to show Americans can run with the best East Africans," Salazar said.

"What we needed was a kid born in this country — here's a kid from the Midwest (Michigan) — able to run with them. This is a huge shot to prove you don't have to be East African to be a great distance runner."

Salazar, a winner of the New York and Boston marathons, has been coaching Ritzenhein for just three months. In April, after finishing 11th in the London Marathon in a personal-best 2:10:00, Ritzenhein decided to leave coach Brad Hudson, whose training group was in Eugene, Ore. By June, Ritzenhein left Eugene for Portland and Salazar's group.
