The race is a checkpoint race. The mission is located inside the Vice Point Mall and can be started by entering the parked BMX bike on display on the northwestern wing of the mall. Once the mission begins, the player must collect 50 coronas within 4 minutes and 30 seconds while on the bike. The coronas are located around the mall, even inside some of the store interiors. There are three types of coronas the player must collect; green coronas, which can only be collected by preforming a wheelie, blue coronas can be collected by preforming stoppies, and red coronas can be collected in anyway.
The reward for completing Mashin' Up The Mall is $500. The player's time is also recorded in the Stats menu. The player can activate this mission again if they want to beat their time.
