The 2025 Cocodona 250 Course Guide - Metric Edition (Kilometers & Meters)

I’ll keep running, running toward the sun And I’ll never let it set again - Rob Riccardo, The Calm Within

Note: This is an experimental course guide. I needed a big challenge to test how my systems scaled, and I couldn’t think of something bigger than the Cocodona 250. For additional context, here’s some of the things I was looking to understand with this experiment:

1. Big Data: Some of the AI models I use to create guides have a strict upper bound on how much data they can process. Cocodona definitely pushed that upper bound.

2. Metric Content: Since I’ve been publishing guides, I’ve found that many non-US runners struggle with US-based races only publishing content using imperial measures (miles, feet, etc.). This guide isn’t intended to replace the phenomenal content Cocodona’s organizers provide. This is an attempt to make that knowledge more accessible to a global audience. As of now I don’t plan on doing an imperial edition of the guide, but I would if a participant requested it.

3. Maps: Attempting to tell the story of a 250 mile (410 km) course requires a lot more from maps than a marathon does. I had to significantly enhance my maps for this course, and I really wish Substack supported embedded interactive maps as they are really fun to play with.

Update: The Imperial Edition (Miles & Feet) of this guide is available here.

Course Overview

The Cocodona 250 stands as an extraordinary point-to-point ultramarathon, beginning at Deep Canyon Ranch in Black Canyon City and culminating in Flagstaff, Arizona. This iconic race spans over 410 kilometers and is celebrated for its unparalleled diversity, traversing the Sonoran Desert, the Bradshaw Mountains, Verde Valley, Sedona's red rock landscapes, and the high-altitude Coconino Plateau before reaching Flagstaff. Runners embark on a transformative journey across Arizona's diverse and challenging terrain.

The 2025 Cocodona 250 Course

The race commences in under twilight at 5:00 AM on Monday, May 5th, allowing participants to navigate the initial desert section during the cooler hours of the day. Competitors must prepare for dramatic temperature variations throughout the event. While the Sonoran Desert and the Verde & Sedona Valleys typically reach daytime highs averaging 29°C, the higher elevations present a stark contrast. The Bradshaw Mountains, Mingus Mountain, Coconino Plateau, and Mount Elden frequently experience nighttime lows between -4°C and 4°C. Participants will encounter both scorching, exposed sections and frigid, potentially windy conditions, particularly during nighttime hours and at higher elevations.

Course Briefing

KM 0-12 (Start to Cottonwood Creek Aid Station)

The race begins at Deep Canyon Ranch, immediately ascending onto the renowned Black Canyon Trail (BCT). Starting before dawn at 5:00 AM, you'll witness the sunrise as you traverse classic Sonoran Desert terrain, distinguished by iconic Saguaro cacti and Ocotillos. The initial section features a climb onto the BCT, followed by rolling doubletrack.

Around KM 5, the course narrows from a wider road to descend into the Slate Creek drainage. Here, you'll encounter your first taste of adventurous terrain with a scramble up a dry creek bed. This segment demands careful footing as you navigate dry waterfall features and loose creek bed material. Exiting the drainage, you'll rejoin the BCT singletrack until the final approach to Cottonwood Creek Aid Station, transitioning to a double-track road for the last kilometer.

This opening 12km section presents a cumulative ascent of approximately 300 meters, preparing you for the varied climbs that lie ahead.

KM 174-202 (Mingus Technical Descent to Jerome Aid Station)

Leaving Mingus Mountain Camp Aid Station, you're immediately greeted with spectacular views across the Verde Valley towards Sedona and Flagstaff. After following the cliff edge for a short distance, the North Mingus Trail veers sharply left, beginning a technical descent. The first kilometer is steep and technical, requiring careful footwork. The trail then eases to a gentler grade on an old roadbed, now eroded to single-track.

After cautiously crossing Hwy 89A, the pine forest transitions to scrub oak and sage, revealing views of the historic Verde Mine and the Verde Valley below. The terrain grows rocky again as you proceed. Eventually, the course guides you past the Verde Mine and into Jerome, a historic mining town. The route winds directly through Jerome, which clings dramatically to the side of the Black Hills, before reaching the aid station. This station offers panoramic views overlooking the Verde Valley, Sedona, and the distant Flagstaff peaks. This section features a substantial descent of approximately 1000 meters, predominantly on technical trails.
