Track and field[edit]
The track and field team was under the direction of John McDonnell for over 25 years (since the 1977–78 academic year). McDonnell's men's teams have won 40 NCAA championships since 1984, including 11 cross country, 19 indoor track and 10 outdoor track along with 37 Southwest Conference Championships, and 38 of 40 SEC titles.[25] The Razorbacks, under his direction, won five National Triple Crowns, achieved by winning NCAA titles in cross country, indoor and outdoor track in the same school year. Arkansas and the University of Texas-El Paso (UTEP) are the only teams to have ever won the National Triple Crown. The track and field Razorbacks men completely dominated the sport during the 1990s, winning 24 of the 30 available titles. Now under the direction of coaches Chris Bucknam, Doug Case and Travis Geopfert, the men's track and field team still dominates the NCAA. They have won multiple triple crowns along with one National Championship since taking over in 2008.
