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 beginner running your first ultra, a 100-mile hopeful or a competitive 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!


**NEW FOR 2023**
We have added a 3-Hour Event for friends and family to participate.

Join us at Crystal Springs Picnic Area for 3, 6, 12, 24 hours & 100-miles of running on the USAT&F Certified Course on the dirt equestrian path around the beautiful Harding Golf Course. How far can you run, jog or walk in 3, 6, 12 or 24 hours? You keep going and we will calculate your mileage for you. Timed ultra marathon races are super fun because you always have someone to run with on a flat course and with support every 2.43 miles, the miles will add up!
