Karie first competed for West Springfield High School, which he attended from the summer of 1993. Despite knowing little English language at the time, he joined the track program. In the spring of 1994, Karie ran his first ever high school mile race in 4:40 (min:sec).[4] Less than two years later, Karie beat Seneca Lassiter in the 1995 VHSL Indoor State Championships for the 3200 meter race, running a time of 9:21.07.[4] Topping off the end of his time with West Springfield High, Karie was named Gatorade track athlete of the year in 1997. To this day Karie is recorded in the all-time top 25 Virginia high school track runners for disciplines varying from the indoor 1000 meters, 1600 meters, and 3200 meters.
Collegiate
For a brief period Karie went to Lindenwood University, but would develop his collegiate track career with University of Arkansas, which was again becoming a recognized track school in the era of coach John McDonnell. In an interesting twist of fate, high school rival Seneca Lassiter was one of Karie's team mates on the Arkansas track team. On April 24, 1999, Karie along with Arkansas teammates Lassiter, Michael Power and Matthew Kerr ran a 4 x 1-mile relay in a time of 16:07.96, the seventh fasted time ever recorded for this relay distance.[6]
