Elkhorn Crest 50 Course Guide

The early climb: high from the gun

You do not get an easy warm-up here. The 50K throws about 2,400 feet at you in the first 5.4 miles, and the 53-mile is climbing into the high country early too. The trap is going out hard because you feel fresh and the views pull you along, then realizing on the crest that you spent a match you needed for the back half. Hike the steep pitches with intent, keep your effort honest, and remember you are already breathing thinner air than you train in.

Once you are up top the course rides the ridgeline through sub-alpine forest and open grassland, trading climbs and descents with huge views out to Baker Valley, the Wallowas, and the Blue Mountains. It is gorgeous, and it is also fully exposed. Wind, sun, and weather all live up here, so it is a place to manage yourself, not gawk and forget to eat.

The ridgeline and The Gauntlet: respect the rock

The middle miles are where the Elkhorn Crest shows its teeth. Stretches of genuinely rocky, technical trail break up the runnable single-track, and the 53-mile hits a half-mile section the race calls "The Gauntlet" that is just relentless rock. You will not run that fast no matter how fit you are, so do not fight it. Quick feet, a short stride, and patience get you through cleaner than forcing the pace and rolling an ankle in the middle of nowhere.

This is also where the altitude quietly compounds. Climbing technical ground above 7,000 feet costs more than the same effort would down low, so your heart rate creeps and your legs sting earlier than the mileage suggests. Keep eating, keep your effort even, and let the rocky parts be slow on purpose.

The descent into Sumpter: fast if you saved it

Both courses trend downhill to the finish, and the 50K in particular drops a couple thousand feet over the closing miles into Sumpter. That is a gift if you paced the day right and a punishment if you did not. Long downhill on tired, altitude-cooked quads beats you up, and the runners who blew the early climb or never trained descending fall apart right here, shuffling in when they should be flying.

Train controlled, runnable downhill before race day so you can actually use this finish. Being able to keep your legs turning over late, when the air is thin and your quads are shot, is what separates a strong close from a long, sad walk to Sumpter.

Aid, gear, and self-reliance

This is remote country, and the race treats it that way. The 53-mile runs through six stocked aid stations (roughly miles 4.5, 9.7, 17.7, 28.9, 36.2, and the finish) with one drop bag allowed, typically at Twin Lakes around mile 28.9. The 50K has three stations (about miles 5.4, 14.5, and 21) and no drop bags. The gaps between them are long and high, so carry enough food and fluid to cover yourself instead of assuming the next aid is close.

Mandatory gear is real here: at least 1.5 liters of fluid capacity, a headlamp (with extra batteries on the 53-mile), a jacket, and an emergency blanket. That kit exists because the weather on an exposed sub-alpine crest can flip from warm sun to cold wind in a hurry. Pack it, know how to use it, and do not treat the list as optional.

Pace the climbs by grade and altitude, not the watch

Your flat-ground pace is meaningless on the Elkhorn Crest. What matters is grade-adjusted effort, and up at altitude you should run even a touch easier than that suggests. Hold a steady output you can sustain up the grade, hike the steep and rocky pitches without guilt, and stop chasing a number. The classic blowup here is hammering the early climbs because the legs feel good, then dying on the descent into Sumpter. A grade-adjusted pace turns your real fitness into honest climbing and descending targets so you do not torch the first half.

Build a vert-aware finish prediction against the cutoffs

Do not guess your Elkhorn finish off a road time. The 10,500-plus feet of climbing, the technical rock, and the thin air all add real minutes, and the intermittent cutoffs (Pole Creek, Twin Lakes, Marble Pass on the 53-mile, mile 14.5 by noon on the 50K) mean a vague plan can end your day early. A vert-aware finish prediction gives you a realistic window and lets you back into each checkpoint, so you know how much buffer you actually have instead of finding out the hard way at an aid station.

Carbs: steady, trained, and don’t let altitude stall you

Aim for around 60 to 90 grams of carbohydrate per hour, leaning to the higher end only if your gut is trained for it. Altitude is the wrinkle here: it kills your appetite and slows digestion, so the deeper you get into the day the harder eating feels. Keep your intake steady and easy to swallow rather than gambling on big late doses, and practice your exact race-day carb rate on long climbs so 80-plus grams an hour feels normal instead of nauseating. On the 53-mile especially, the runners who keep eating past dark are the ones still moving.

Sodium and fluid: plan for the gaps and the night

Carry enough fluid to cross the long, high stretches between aid stations, not just enough to reach the next one. The mandatory 1.5-liter capacity exists for a reason, so use it. On sodium, most runners do well around 500 to 700 milligrams per liter of fluid, more if you are a heavy or salty sweater. Weigh yourself before and after a hard long run to find your real sweat rate, then build the plan around your own number. And remember nights up high get cold, so pack a little extra food for the late hours when your body is burning energy just to stay warm.
