It was in the headlines last fall when Salazar, the leader of the Nike Oregon Project team, he was banned for four years for his aggressive experiments with supplements and testosterone. According to the report detailing the circumstances that led to Salazar's ban, Ritzenhein was one of the first athletes to question whether infusions of a supplement called L-carnitine were performed in accordance with anti-doping regulations.

Ritzenhein's career was marred by injuries. In his post, he thanked his coaches and support staff for helping him overcome the ailments.

I kept you very busy! he wrote. I had many setbacks along the way. But I always had people who were there to help put the pieces together and get back to the starting line.

Ritzenhein was a standout in the University of Colorado , where he won a cross country title in 2003 and finished second in the 5,000 meters at the 2004 NCAA Athletics Championships.

It was truly (an) incredible journey, he posted. I am looking forward to the next chapter!
