Set in the rugged and scenic mountains of eastern San Diego County, the Noble Canyon 50K & 15K Trail Races deliver a high-desert adventure steeped in raw beauty and trail running grit. Whether you’re chasing an ultra challenge or testing your speed on the shorter course, this race offers an unforgettable experience through the Cleveland National Forest — a wild and protected landscape that feels miles away from the city bustle.
This USATF-sanctioned event is operated under a special permit on National Forest land, with the USDA as an equal opportunity provider, employer, and lender.
Course Description
Both courses start and finish at 8631 Pine Creek Road in Pine Valley, CA. The 50K begins with a mandatory pre-race briefing. Runners can expect a rugged out-and-back journey through the historic Noble Canyon Trail system — a course known for its rocky climbs, exposed ridgelines, and fast descents. The terrain is technical and varied, featuring stretches of pine forest, open granite-studded slopes, and canyon switchbacks that offer sweeping views of the Laguna Mountains.
The 15K kicks off after a briefing and provides a shorter, but still challenging taste of the same rugged terrain. It’s perfect for newer trail runners or those looking for a fast and scenic mountain race.
Elevation gain is significant on the 50K, rewarding those who come prepared for a true mountain ultra. With temperatures that can shift quickly, runners should be ready for heat in the canyons and crisp winds at higher elevations.
Aid Station and Support
Runners will be supported by a team of dedicated volunteers across multiple well-stocked aid stations (locations and exact mileage will be shared in the race packet). Expect hydration, electrolytes, and essential fueling options to keep you going through the ups and downs of the course.
Course volunteers also assist with safety across highway crossings, shuttling supplies, and helping runners stay on track throughout the event.
Moctezuma Photography will be on course capturing the action. Each participant will receive one free race photo or $9 off selected purchases. And keep an eye out for video coverage from Robin Martin—be sure to wave and smile!
Runner Experience
The Noble Canyon experience is as much about community as it is about competition. From the early morning buzz of race day parking to the trail camaraderie shared along the climbs, this event draws trail runners who respect the challenge and embrace the beauty of the wilderness. Race parking opens at 5:00 AM, with on-site parking available and directed by staff.
The vibe is low-key, runner-focused, and built around the joy of running hard in a beautiful place. Whether you’re pushing for a PR or soaking up your first trail race, the Noble Canyon atmosphere will lift your spirits all the way to the finish line.
Don’t forget to tag your race day and training moments with #NobleCanyon50K — your stoke might just inspire someone else to toe the line next year.

It was very nice having differing sceneries along the course: Pine trees, rocks, sand, a lake, and some hills but not a lot elevation change. There was not loop, and it didn’t get boring. It was cool this year, which (I was told) was unusual. Few, but well stocked aid stations along the course.
