Alex Collins beat players from Alabama and Ohio State in his final appearance in an Arkansas uniform.
A month after rushing for 185 yards and three touchdowns in the Liberty Bowl, Collins won the Marines obstacle course race at the All-Star Football Challenge at AT&T Stadium in Arlington, Texas.
He finished the course in 30.9 seconds, which was ahead of Ohio State linebacker Darron Lee (32.6 seconds) and Alabama linebacker Reggie Ragland (34.2).
The event took place Tuesday, but was taped and televised on ESPN2 Friday night.
