TikTok users in Los Angeles are going viral for a bizarre new trend where they run into Scientology buildings to see how far they can get before being stopped and thrown out.

The clips, often filmed in Hollywood, show creators rushing through the front doors, sprinting down hallways, and sometimes even using skateboards to push deeper into the building. The goal is simple: make it as far inside as possible.

The challenge has quickly been dubbed the “Scientology run,” with users trying to one-up each other after one viral clip claimed to show the “deepest recorded run.”
