WELCOME TO 2021 CIRQUE DU Griffith Park

We know you have many races to choose from and we thank you for supporting this amazing event in beautiful Griffith Park. Whether you’re a “newbie” running your first ultra, a 100-mile hopeful or a competative pro, we promise to give you a safe and professional race experience. Trail Run Events brings you 20-years of awesome races in beautiful places and Cirque is our crowning glory!


Join us at Crystal Springs Picnic Area for 6, 12, 24 hours & 100-miles of running on the dirt equistrian path around the beautiful Harding Golf Course. Located in historic Griffith Park, you can run to your heart’s content while the family takes in the sights of Hollywood or just enjoy the many attractions inside the park.

How far can you run, jog or walk in six or twelve hours? You keep going and going and we will calculate your mileage for you. Timed ultra marathon races are super fun because you always have someone to run with and with a flat course and support every 2.43 miles, the miles will add up! In addition to our Saturday events, we present a 100-mile run that is user-friendly for everyone! You know you want that buckle and we will help you get it!


Due to the possibility of race cancellation due to Covid-19, we have a feature where you can sign up for the race today but your credit card won’t be charged until we confirm our permit . Once we know for sure that the race is a “GO”, we will notify you to authorize your payment.

Think of it as an RSVP for the race or a waitlist, only the race isn’t full. It just holds your place in the race until we know for sure that the park will allow us to move forward.

This is a “WIN WIN” because you don’t have to pay anything right now and this lets us know if runners are actually interested in running with us in June.
