This mini game appears after your first date with Damien. It features a running simulator that appears to be paying homage to Wii Sports Resort.
Craig texts you that he has the runs. You give him a diarrhea cure, only for him to say he meant he wants to go running. You leave your reality show to go with. At the gym, the treadmills have a new interactive mini game where a mini you and a mini Craig run on scenic pathways, passing other avatars.
On the switch, you toggle the left joystick rapidly to run.
