This event offers a 29-mile Ultramarathon and a Half Marathon, and it’s set to take place on the pristine grounds of the Grupe Family Ranch, a sprawling 9,000-acre private property.

This is no ordinary trail race – it’s a unique opportunity made possible by the generous Grupe family, who have opened their property to the Pacific Coast Trail Runs community. G-Bar Ranch, the namesake of the event, takes its title from the historic livestock brand associated with the ranch. It’s important to clarify that it’s not named after Greg, the race director, who may enjoy open bars at his events – this is about the ranch’s legacy.

What makes this year’s event even more special is its inaugural status. It’s the first time that trail runners will have the privilege of exploring the G-Bar Ranch in an official race capacity. You’ll be part of history, inaugurating a new era of trail running in this pristine location.

Whether you’re an experienced ultramarathoner or a newbie looking for a unique adventure, this event caters to everyone. The beauty of the Grupe Family Ranch and the historical significance of the G-Bar brand create a unique backdrop for an unforgettable day of trail running.

In a world where many trails have been explored, this race offers a chance to tread on new ground, forging a connection between the past and the present, and between the runners and the land. It’s an opportunity to make history and to run where few have run before.
