Use the Torgue Tournament Sign-in Terminal to sign in to the tourney. Then proceed underneath the sign that says "Fully Torgued". Use the Catch-A-Ride station to your right to get a vehicle. Jump the ramp that has the red arrow on both sides. There are some other ramps you can jump over if you want to have fun with the vehicle.
After clearing the enemies, find Piston who is giving a television interview at the entrance to the Colosseum and talk to him, to complete this mission.
