country season he finished in fourth place at the NCAA Cross Country Championships with a time of 29:11. His finish along with the second-place finish of teammate Jorge Torres helped lead Colorado to the team title. The following spring he competed in the 5000 m race at the NCAA Track and Field Outdoor Championships, finishing again in fourth place with a 14:01.02. His 5000 personal record during that season was 13:27.77. Stress fractures caused him to decide to redshirt his sophomore year in both cross country and track. In the fall of 2003, Ritzenhein once again competed in cross country. He won the Big 12 title, and then outkicked Ryan Hall of Stanford to win the NCAA Cross Country Championships individual title. His winning time was 29:14.1. In the spring of 2004 Ritzenhein ran a 27:38.50 in his debut at 10,000 m at Stanford. The next day he won the 5000 m at the Big 12 Outdoor Conference Championships. Ritzenhein concluded his collegiate season by placing second to Robert Cheseret of Arizona in the 5000 m at the NCAA Outdoor Track and Field Championships. Ritzenhein harbored hopes of competing in the Olympic Games at the end of the summer in Athens, but shortly after the NCAA meet he developed a stress fracture in his foot. He limped through the Olympic Trials in the 10,000 m, finishing last, but was able to make the team because the two other athletes with Olympic qualifying times did not go to Athens, Bob Kennedy having dropped out of the Olympic Trials race with an Achilles tendon injury and Meb Keflezighi choosing to focus solely on the marathon. Ritzenhein ran the Olympic 10,000 m, but dropped out mid-race due to pain caused by his stress fracture. Shortly after the Olympics he decided to forgo his remaining collegiate eligibility in order to run professionally. At this time he changed coaches from Mark Wetmore to Brad Hudson. 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.
