We, at Keira Henninger Races, are proud and excited to hold the inaugural running of the Griffith Park Trail Marathon this spring. We created this event to give an opportunity for runners to accomplish running on trails longer than they ever imagined possible. This is a faster course with some solid good hills, and up to fourteen flat fast runnable miles. You will cross paths with historical landmarks that Griffith Park offers, and experience the magic that this special place holds.

This course will have seven well stocked and well manned aid stations, and no detail will be overlooked in the process to make this the best experience a runner could have on the trails. All runners will have 8 hours to complete this magical Trail Event.

It will start and finish in the same location as our sister race the "Griffith Park 10k" , and even touch on some amazing parts of our Griffith Park Trail Half Marathon course.

Important Participant Information

To protect the natural beauty of the park and for the enjoyment of the participants and other park users, we are limiting the number of entries to 400 runners only.
