Dathan Ritzenhein - Post-collegiate/professional

Post-collegiate/professional

Ritzenhein began his professional career on December 31, 2004 when he finished 3rd in a 10 km road race in Italy. In January 2005 he won the prestigious Belfast International cross country race, and seemed to be in great form. Ritzenhein won the U.S. Cross Country Championships in the 12 km for his first senior national title. Before the World Cross Country Championships expectations were high and some prognosticators even predicted a top 10 finish, but Ritzenhein faded after going out with the leaders and ended up placing 62nd. Ritzenhein's 2005 track season began with a 13:22.23 5000m personal record and a 7:43.95 3000m. In a much anticipated 2 mile race that included high school rival Alan Webb, Ritzenhein ran 8:23.45, which was a solid performance, but was overshadowed by Webb's 8:11.48 for the American record (the next year, they would switch times). A few days before the U.S. Outdoor Track Championships Ritzenhein injured a nerve on his foot while kicking around a soccer ball bare foot with his dog. This injury effectively ended his season.

On February 19, 2006, Ritzenhein faltered in the USATF national cross-country championships at Van Cortlandt Park. Leading with Hall and Jorge Torres for several circuits of the 12K course, he dropped off badly near the end as Ryan Hall ran away from the field. Ritzenhein finished nearly a minute behind Hall and finished fourth in the race. He qualified for the team but appeared to be hurting badly after the race, leading some to question his fitness heading into the IAAF World Cross-Country Championships April 1–2. Ritzenhein was diagnosed with walking pneumonia after the USATF national cross-country championships and forfeited his spot on the US team.

He again competed against Alan Webb in a 10,000 meter race at the Cardinal Invitational at Stanford University on April 30, 2006. Prior to the race Webb and Ritzenhein agreed to alternate leading the race for the first 24 laps. The last lap would be "every man for himself." Webb's mid-distance background allowed him to outkick Ritzenhein for the win, 27:34.72 to 27:35.65, a personal best for both runners. In the 5000 m at the U.S. Outdoor Track Championships Ritzenhein finished 3rd behind Bernard Lagat and Matt Tegenkamp. Ritzenhein's time of 13:16.61 was a personal record. He then went to Europe and ran two 5000 m races. He won his first race in Switzerland, and then ran respectably in an elite field in Rome.

Ritzenhein made his Marathon debut in the 2006 ING New York City Marathon, finishing in 11th place with a time of 2:14:01.

Ritzenhein finished second (2:11:07) in the 2008 Olympic Marathon Trials which automatically placed Dathan on Team USA for the Beijing Olympics.

In the 2008 Olympic Marathon, Ritzenhein was the first American Runner to cross the finish line, finishing 9th with a time of 2:11:59. His teammate, Ryan Hall, finished just behind him in 10th place.

In January 2009, Ritzenhein placed 2nd at the U.S. Half Marathon Championship. Three months later, he set a personal best at the 2009 London Marathon, finishing 11th in 2:10:00.

In May 2009, Ritzenhein and longtime coach Brad Hudson parted ways. He moved from Eugene to Portland, Oregon in order to train with Alberto Salazar's Nike Oregon Project.

On August 17, 2009, Ritzenhein placed 6th in the 10,000 metres at the World Championships in Berlin, Germany. He set a personal best of 27:22.28 in that race.

Just eleven days later at the Weltklasse Meeting in Zurich, Switzerland, Ritzenhein placed 3rd in the 5,000 metres, setting a new American record with a time of 12:56.27. He became just the third American to run under 13 minutes in the 5,000, as well as the third fastest non-African of all time in that event behind Dieter Baumann and Craig Mottram.

At the World Half Marathon Championships, in Birmingham, Ritzenhein placed third with a time of 60:00. That time is the second fastest American time ever just behind Ryan Hall's 59:43. Ritzenhein finished just one second behind the second place finisher. With his 1 hour and 25 second personal best time, Dathan became the first American to go home with a medal from these World Championships.

In the January 2012 Olympic Marathon Trials, Ritzenhein ran a personal best 2:09:55, but placed 4th, narrowly missing a spot on the US Marathon Team by 8 seconds behind the 3rd place finisher.

On the evening of June 22, 2012, Ritzenhein placed third in the US Olympic Trials in the 10k and successfully achieved the Olympic 'A' standard of 27:45.00. Conditions were extremely rainy and cold, and he had not yet achieved the Olympic 'A' standard before the race. He and his teammate and training parter, Galen Rupp, worked together to pace the race for the first 5000 meters, with Rupp pulling away to win it in the final three laps.

On August 4, 2012, at the 2012 London Olympics, Ritzenhein finished 13th in the 10,000m finals with a time of 27:45:89 behind winner Mo Farah (27:30:42) and second place finisher Galen Rupp (27:30:90).
