Dathan Ritzenhein's 2012 season was one of success and redemption. He finished in the dreaded fourth place position at the U.S. Olympic Trials marathon before redeeming himself by grabbing at spot in London in the 10,000m. His season concluded with a personal best time of 2:07:47 at the Chicago Marathon. The former American record holder in the 5,000m, Ritzenhein was the top finishing American in the men’s marathon at the 2008 Olympic Games in Beijing, finishing in ninth place in 2:11:59. Just prior to the 2004 Olympic Trials, Ritzenhein incurred his third career stress fracture in his foot. Despite the pain, Ritzenhein competed at the Trials and ended his 10,000m race in Sacramento in 22nd place, fully breaking his foot in the process. Having already secured the “A” qualifying standard for the Olympics, Ritzenhein earned his spot on the team when Meb Keflezighi decided to only compete in the marathon at Athens, and Bob Kennedy was unable to finish his Trials race due to a sore Achilles. Ritzenhein owned the American 10,000m collegiate record (27:38.50), four Big 12 Conference titles (2003 cross country, 2004 indoor 3,000-m, 5,000-m and outdoor 5,000m), four All-American titles (2001, 03 cross country, 2004 indoor and outdoor 5,000m), the 10,000-m school record (27:38.50) and the nation’s only undefeated cross country season in 2003 to capture his first and only NCAA crown. During 2003-2004, he won the Pre-National Invitational, Big 12 Cross Country Championship, NCAA Mountain Region Championship, and NCAA Championship just 10 weeks after resuming training following a femoral stress fracture to cap off the nation’s only undefeated season (792-0). During the outdoor campaign, he finished sixth at the Stanford Invitational in an Olympic Trials “A” Standard, American Collegiate Record and 31-year CU School Record 27:38:50 in his first-ever 10,000m on the track. Decided to forego his collegiate eligibility to turn pro during the summer of 2004. Dathan married Kalin Toedebusch on June 30, 2006.
