Course Character: Aggressive net downhill; point-to-point.

This is the race you run when you want to see a number on your watch you didn't think was possible. It is not a "fun run" for those who hate quad-smashing descents; it is a precision tool for chasing a personal best.
71St Annual Fontana Days Run 2026 takes place on Saturday, June 6, 2026, in Fontana, United States. The event offers a Half Marathon, 5K Run, 5K Family Walk, and a Children’s Half Mile Dash. It is widely recognized as one of the fastest half marathon courses in the world due to its significant elevation drop.
What is the course profile actually like?
This is a point-to-point descent that drops roughly 2,125 feet from the San Bernardino National Forest down to Fontana City Hall. It is a steady, runnable decline rather than a series of technical plunges, which is why it’s a PR factory. You can view the official route on Fontana Ca ↗. Warning: The gravity will tempt you to redline too early. If you don't have strong quads to handle the eccentric loading of a 13.1-mile descent, your legs will be jelly by mile 10.
How do I manage the race day logistics?
The logistics are non-negotiable because of the mountain start. You cannot drive to the start line. For the Half Marathon, you must catch the mandatory shuttle buses departing from Fontana City Hall between 5:00 AM and 6:20 AM. If you miss that 6:20 AM cutoff, you are out of luck. I highly recommend picking up your packet on Friday between 4:00 PM and 8:00 PM at City Hall to avoid the 5:00 AM race-day scramble.
What are my distance and start time options?
The Half Marathon is the flagship event, starting at 7:00 AM. If you aren't looking to smash a record, the 5K Run starts at 7:45 AM, followed by the 5K Family Walk and the Children’s Dash. For serious competitors, the Half Marathon is the only logical choice here.
Will I be running in the heat?
You start in the San Bernardino National Forest at 3,800 feet, where the air is thinner and significantly cooler. However, as you descend into the Fontana valley, the temperature will climb steadily. By the time you hit the urban finish at City Hall, June in Southern California can get spicy. Plan your hydration accordingly for that transition from mountain air to valley heat.
Is there anything waiting for me at the finish?
Yes, the organizers lean into the community feel at the finish line with vendors, food, and entertainment. All finishers receive a medal. If you are an elite or a local, there is real skin in the game: prize money is available for top finishers in the Half Marathon and 5K, with additional bonuses for Masters (40+), Fontana residents, and anyone brave enough to break a course record.
