Chino Hills Trail Run Series Fall
Chino Hills Trail Run Series Fall is a trail running event in Brea, California, held in November 2026. The event uses routes through Chino Hills State Park, with start and finish at the Discovery Center parking lot, 4500 Carbon Canyon Road, Brea, CA 92823.
Distances:
- 50K course through park trails
- 30K course sharing many turns with the 50K
The courses traverse hillsides, chaparral, and oak woodlands and include rugged sections and scenic viewpoints. Aid stations are placed along the routes and include Telegraph Canyon/Little Canyon (water and snacks), 4-Corners (mid-station), and Bane Canyon (drop bag station). Provided mile markers specify locations for each distance—for example, Telegraph Canyon/Little Canyon appears near mile 4.5 on both courses; Bane Canyon serves as a turnaround for the 30K and a multi-checkpoint station on the 50K.
Parking is at the Discovery Center lot with a $10 fee. When that lot is full, runners are directed to Carbon Canyon Regional Park far east lot next to the state park with a $5 entry fee, or to Olinda Ranch Park which is free but about a one mile walk to the start. An early bib pickup is offered at Snail's Pace Running Shop, 1040 E Imperial Hwy, Brea, CA 92821. Registration pricing is listed between USD 110.00 and USD 163.25.
