Since its inception in 2024, the Gila 100 has grown steadily, drawing participants who appreciate the blend of natural beauty and community enthusiasm. The event raises funds for local trail maintenance and conservation efforts, directly impacting the trails runners will traverse during their journey.

The race courses wind through various terrains, including forests, meadows, and rocky outcrops, providing runners with a mix of firm and slightly soft trail conditions underfoot. The start line at the Santa Clara Armory is also where participants collect their bib numbers before heading into the wilderness. Aid stations are strategically placed along both routes to ensure that runners have access to water, snacks, and medical support as needed.
