This isn't a race for those looking to cruise on flat dirt. You are running on the Coconino Plateau, which means the air is thin and the terrain demands respect. If you want a well-run, high-altitude mountain experience that won't leave you broken for a week, this is the one.
Flagstaff Extreme Big Pine 2026 takes place on Saturday, June 20, 2026, in Flagstaff, United States. The event offers 50K, 27K, 13K, and 6K distances. It is a quintessential Arizona mountain run set amidst towering Ponderosa pines.
What can I expect from the terrain?
The course is classic Coconino Plateau: well-maintained singletrack that rolls through dense forest. It isn't "technical" in the sense of rock gardens and talus, but don't let the "well-maintained" label fool you—the constant undulating terrain and high elevation (peaking at 7,701 ft) will sap your legs.
For the 50K, expect 2,440 ft of gain. For the 27K, it’s a more manageable 1,293 ft. Use these maps to scout your effort: Caltopo ↗ for the long haul or Caltopo ↗ for the shorter distances.
Which distance should I pick?
If you want the full mountain experience, the 50K is the flagship. It’s a serious test of aerobic capacity due to the altitude, but the aid stations are spaced reliably every 4 to 7 miles. If you are looking for a high-intensity trail workout or a "test" run, the 27K is the sweet spot—it offers enough climbing to feel like a mountain run without the 10-hour grind. The 13K and 6K are great for local enthusiasts or those just acclimating to the thin air.
What is the weather and gear situation like?
June in Flagstaff is beautiful but deceptive. You’ll likely start in the cool, crisp mountain air, but the sun at 7,000+ feet is aggressive. Expect temperatures to climb quickly once you’re moving. I recommend moisture-wicking layers for the start and a hat/sunscreen for the mid-morning heat. The shade from the Ponderosa pines is a lifesaver, but once you hit the ridges, you are exposed.
How do I handle the logistics and aid?
Aravaipa is known for being "no-nonsense," which is exactly what you want. Aid stations are frequent (every 4.0 to 7.3 miles), so you don't need to carry a massive buffet on your back, but you should still carry enough hydration to manage the dry mountain air. Note the cutoffs: the 50K has a 10-hour limit, so if you aren't a mountain specialist, watch your pace early. You can track your progress via Aravaipa ↗.
What do I get for finishing?
This isn't a race for cheap plastic medals. You’ll walk away with either a branded Campfire Mug or a wooden Artworx finisher award—stuff you’ll actually want to keep on your shelf. You also get a gender-specific race shirt and the standard chip-timed bragging rights. Plus, if you're feeling adventurous, there's a 25% discount for local ziplining to help you recover (or distract yourself from the soreness).
