Go through single player Nationals, and earn the Mils Mesas environment or enough points to purchase it. After getting this map, exit the mode that you are in, and go to single player. Choose the custom event option, then go to "Nationals". Select the Mils Mesas track. Set the play mode to "Single Play", laps to "10", and number of opponents to "0".
