Davis first gained fame while running for San Diego High School (the same alma mater as American distance star Meb Keflezighi), winning the 1986 Foot Locker Cross Country Championships - which at the time was the only high school national championship contested - on his home course before a national TV audience.[1]
As a professional, he won the 1993 USA Outdoor Track and Field Championships 3000m Steeplechase, and in 1998 he won the USATF 5000 metres.[3][4] On the roads he won the 1997 USATF National 5K Championship.[5] Davis ran an American Record time of 13:24 for the 5K on the roads in 1996, and that record lasted 19 years until Ben True broke it in 2015.
At the 1996 Summer Olympics, Davis won his semi-final in the steeplechase,[6] but because of an injury, he finished only 12th in the final.
