Dathan James Ritzenhein (born December 30, 1982) is a retired American long-distance runner, and current head coach of the On Athletics Club (OAC). He held the American record in the 5,000 metres (12:56.27) from 2009 to 2010, until it was broken by Bernard Lagat.[2] He is a three-time national cross country champion with wins at the USA Cross Country Championships in 2005, 2008 and 2010. Formerly a Nike athlete for the majority of his professional career, Dathan joined the Hansons-Brooks Distance Project team in 2017. In early May 2020, he announced his retirement from competition. He signed with the Swiss shoe brand On shortly thereafter in June 2020 and currently acts as the coach for the OAC in Boulder, Colorado.
Ritzenhein was a standout runner at Rockford High School in Michigan and the University of Colorado at Boulder. He was part of the stellar high school class of 2001 that also produced American high school and overall mile record holder Alan Webb and American half-marathon and marathon record holder Ryan Hall.
