A 1988 graduate of Simpson College, Janvrin had an outstanding collegiate career, winning three NCAA Division III championships in the decathlon, including a (new-javelin) Division III decathlon record of 7528 points in 1987. In addition, Janvrin won individual titles in the pole vault (16-5 1/2”/5.02m) and 400m hurdles (52.02) in 1988. For years Janvrin was ranked as one of the world’s top decathletes, winning the 2001 USA Outdoor Track & Field Championships. He reached the pinnacle of his career in 2000 as a member of the U.S. Olympic Team in the Sydney Olympic Games. In Sydney, Janvrin, the oldest U.S. decathlete to ever compete in the Olympics, placed 21st and was the winner in the 1500m. He is the world record holder for most career decathlon wins (41) and the American record holder for most career decathlons over 8,000 points (26). After placing fourth in the decathlon trials, Janvrin just missed making the 1996 U.S. Olympic Team. Later that summer, he scored a personal-best 8,462 points, which, at the time, made him the sixth-highest performer in U.S. decathlon history. In the fall of 2003, Janvrin set a world record in the double decathlon, competing in 20 track & field events over two days in Turku, Finland.
