The Gunstock Ranch Trail Run is back! Join us this October 18, 2025 for an incredible trail run through a working horse and cattle ranch on Oahuʻs north shore! Gunstock Ranch sits on 900 acres based against the Koʻolau mountains and offers breath-taking views of windward Oahu as well as the Hawaii Legacy Forest, a protected area filled with thriving native Hawaiian trees. The 5K and 10K routes are very challenging, unique, and offer a beautiful running experience. We are excited to welcome you to Gunstock Ranch for a special opportunity to run on our trails!
