Christian Ramirez is a cable technician from Los Angeles, CA, who competed on American Ninja Warrior 3. He became known on the course for wearing a blue shirt and ski mask while running, as well as for his nickname; "The Blue Runner".
In qualifying, Christian had a fast but slightly sloppy pace through the first three obstacles, becoming just the second competitor to reach the Jump Hang. However, he had too much momentum and hit the front edge of the trampoline, shooting him forward and causing him to not get a good grip on the net with his right hand, sending him into the water and ending his run.
