The course
The race runs on single track and dirt road through Cave Creek Regional Park, the Maricopa Trail, Spur Cross Ranch Conservation Area, and the Tonto National Forest. It is classic Sonoran desert: rock, sand, gravel, and saguaro, mostly runnable, with climbs that roll instead of stacking into one big mountain. The 35K and 50K head out of the park along the Maricopa Trail to Spur Cross and back, then finish with a loop in Cave Creek Regional Park. The 50 Mile follows the same line but keeps going north past Spur Cross into the Tonto backcountry, a full route listed at around 5,100 feet of climbing.
Runnable desert, not a mountain grind
Unlike a big alpine ultra, Elephant Mountain rewards steady running. The trail is mostly runnable, with rolling desert grades, the odd rockier or sandier section, and a steeper pitch here and there instead of thousands of feet of sustained climb. And that makes it really easy to start too fast, because nothing in the first hour forces you to slow down. The trick is to settle into an effort you can hold early and save your legs for the second half, when the sun is higher and the footing has started to wear on you.
The footing is the quiet difficulty. Desert singletrack is full of loose rock, gravel, and sand that punishes you the second you stop paying attention or your feet get tired, so pick your line, lift your feet on the rocky parts, and protect your ankles and toes. Gaiters and a shoe with real rock protection pay off here.
Out to Spur Cross and back
The signature stretch on the 35K and 50K is the run out along the Maricopa Trail to Spur Cross Ranch Conservation Area and back, some of the best singletrack around here. Spur Cross is the turnaround and the drop-bag point for the 50K and 50 Mile, so treat it as the hinge of your whole race: restock fluid and calories, reset your head for the trip back, and leave with enough to cover those exposed miles back into the park.
On the 50 Mile, instead of turning at Spur Cross you push north into the Tonto National Forest backcountry, the wildest and most remote part of the day, before turning back toward the finish. That extension is where the 50 Mile earns its roughly 5,100 feet of gain, and where being self-sufficient between aid stations matters most.
Sun and exposure, not a heat wave
Early February in Cave Creek is usually mild, with daytime highs often in the mid 60s Fahrenheit, cool mornings, lots of sun, and very little rain. Next to an Arizona summer that is gentle. But the strong low-angle desert sun and the dry air still pull real fluid out of you over a long day, and there is almost no shade on the open desert sections. A warm year can push the afternoon higher than the averages let on.
So respect the conditions even when the thermometer reads moderate. Plan your sun protection, dress in layers you can shed after the cool start, and keep your hydration and sodium discipline up across the exposed miles. The desert dehydrates you quietly, long before you ever feel hot.
Aid stations and self-sufficiency
Aid stations sit roughly every 3 to 7 miles with water, electrolyte drink, sweet and salty snacks, and fruit. This is a cupless event, so carry your own reusable cup or soft flask. Drop bags are allowed at the Spur Cross aid station for the 50K and 50 Mile, and pacers are usually only allowed on the 50 Mile at designated aid stations.
Even with aid that often, plan to carry enough fluid to cover the longest gap on a hot, exposed stretch, especially on the 50K and 50 Mile out toward Spur Cross and the Tonto backcountry. And confirm the current aid locations, start times, and cutoff chart on the official Aravaipa Running race page, because the details can change year to year.
Pacing strategy for the Elephant Mountain Trail Runs
A runnable desert course rewards holding back early and running steady late. The trap here is not some giant climb. It is starting too fast on friendly trail and paying for it in the sun-baked second half.
Pace by effort, not by the fast early miles
Because so much of this course is runnable, your first hour can feel way too easy and your watch can show a pace you have no business holding all day. Run by effort instead. Settle into a controlled, conversational effort on the way out to Spur Cross, power-hike the steeper or sandier pitches instead of forcing them, and let the runnable terrain do the work. Negative-splitting the back half is very doable here if you hold back early.
Our free grade-adjusted pace calculator and our how-to-pace-an-ultramarathon-by-effort guide help you turn your flat fitness into honest effort targets across these rolling desert grades, so you are pacing the course in a way you can hold instead of chasing the easy early miles straight into a back-half fade.
Set a realistic goal for the distance and terrain
The desert footing, the sun, and the rolling climbs all slow you down compared with a flat road effort, so set your goal time off the terrain, not a road PR. Use our vert-aware race time calculator to fold the rolling gain into a projected finish for the 35K, 50K, or 50 Mile, and our race equivalent calculator to gut-check that goal against a recent race result before you lock it in.
Then build your plan backward from the aid stations and any published cutoffs, with a comfortable buffer. Knowing your target pace into and out of Spur Cross keeps you honest on the exposed return, when it is tempting to either over-push or just drift.
Manage the sun and the exposed return
The hardest pacing calls come on the open, shadeless return miles, when the sun is highest and your legs have soaked up all that early rock and sand. Do not bank time early in the cool air that you cannot hold once it warms up. Keep your effort even, manage your core temperature with fluid and whatever cooling the aid stations have, and let the back half come to you.
If you are new to the desert, treat it like a hot race even when the forecast looks mild, and lean on our heat-training-and-acclimatization-for-ultras guide in the weeks before, so the dry sun is not a surprise on race day.
Fueling strategy for the Elephant Mountain Trail Runs
The dry desert air is the thing that catches well-trained runners out here. You sweat more than you notice, so hydration and sodium matter just as much as carbs on this course.
Carbs: a steady hourly target on a trained gut
For something from 35K to 50 Mile, aim for roughly 60 to 90 grams of carbohydrate per hour, leaning toward the higher end on the longer distances once your gut is trained to take it. Use a glucose-plus-fructose blend so you can absorb more than a single sugar lets you, and rehearse your exact hourly number on long training runs so it feels routine, not like an experiment, by race day.
Our how-to-build-an-ultramarathon-fueling-plan guide and our how-many-carbs-per-hour-for-an-ultramarathon breakdown walk you through picking and practicing a number you can actually stomach across the whole race.
Sodium and fluid: built for the dry desert
The dry desert air pulls sweat off you that you never feel, so push your sodium toward roughly 500 to 800 mg per liter of fluid, dialed to how salty a sweater you are, and carry enough to cover the exposed gaps between aid. Cramping, a sloshy stomach, and that wrung-out late-race feeling are usually fluid and sodium problems, not fitness problems. Our how-much-sodium-per-hour-for-ultra-running guide helps you find your band.
Dial in a plan for yourself with our free ultra fueling calculator. Enter your weight, goal time, and the conditions you expect, and it gives you a carb, sodium, fluid, and caffeine number per hour built for the Elephant Mountain distance and that dry desert sun. Then go test it in training, and use the Spur Cross drop bag to restock exactly what your plan calls for.
