This season, he had to compete as a walk-on. He was one of several walk-ons to be part of Michael Poston's journey, as shown on ANWNation.

Poston revealed that Castaneda was selected in Oklahoma City, but was picked to late to run the course (he was the eighteenth walk-on selected). However, Castaneda was later selected in Tacoma as the very first competitor to be picked.

His actual run was cut, but it lasted very short, as he failed just the second obstacle, the Lunatic Ledges.
