⏵ Course guide · Grassroots Palouse ultra since 1978
Palouse Road Runners has been sending runners up the spine of Moscow Mountain since 1978, and Moscow Mountain Madness still runs on the same volunteer-powered, technical-singletrack formula: 50K, Half Marathon, and 5 Mile options on trail that rarely repeats itself. I will walk you through the terrain and cutoff first, then give you a pacing and fueling plan built for rugged Palouse singletrack, plus free tools to dial in your own numbers.
These facts come from the official Palouse Road Runners race page. Check the current year details, cutoffs, and aid stations before you commit. Race logistics change year to year.
Whether you run 5, 13.1, or 31 miles, the course stays mostly on technical singletrack along Moscow Mountain, with some fast logging roads mixed in. The club's own site is upfront that this is rugged, technical trail, smoothed only by good footing and Palouse views that keep you smiling through the climbs.
The 50K route is built to give a full tour of what Moscow Mountain has to offer, exploring vast trails and rarely repeating terrain rather than looping a short section. It came back in person in 2024 after positive feedback and demand from the community, with frequent aid station stops and support along the way.
The current half marathon course dates to 2011, and the 5 Mile gives a shorter introduction to the same technical singletrack and logging-road mix. Both share the mountain's serious up, serious down character on a smaller scale than the 50K.
This race began in 1978 with about 60 runners, took a hiatus in the late 1980s, and was reinstated in 1992. Bikers were briefly allowed before the bike race was dropped in 2010. It remains entirely volunteer-run, with proceeds going to local nonprofits, and the club is upfront that these races do not happen without volunteers.
The 10-hour cutoff works out to about 18.66 minutes per mile average, generous on paper for technical singletrack, but the aid station cutoffs along the way mean you need to hold that pace throughout, not just average it at the finish.
A grade-adjusted pace target helps on the climbs, but Moscow Mountain's technical singletrack will also slow your flat and downhill sections compared to smoother trail. Build a realistic per-mile number that accounts for footing, not just elevation change.
Because the race enforces aid station cutoffs to keep volunteers able to sweep the course, a finish-time projection checked against your actual splits early in the race tells you whether you are on pace to clear each aid station, not just whether you can theoretically finish inside 10 hours.

Early October on Moscow Mountain typically runs cool, but a full day out on technical singletrack for the 50K still adds up in fueling and hydration needs.
Aim for roughly 60 to 90 grams of carbohydrate per hour on the 50K, using the frequent aid station stops and support along the route to stay consistent. The Half Marathon's water stops at miles 5.5, 9.5, and 10.75, and the 5 Mile's stop at mile 3, are further apart, so plan what you carry between them.
Sodium in the 300 to 700 mg per liter range covers most runners on an October day in the Palouse. Technical, rooty, uneven footing costs more energy than the same distance on smooth trail, so do not shortchange your intake just because the temperature feels mild.

This is a wickedly rugged race by the club's own description: mostly technical singletrack along the spine of Moscow Mountain with some fast logging roads mixed in. The 50K carries a 10-hour cutoff, about 18.66 minutes per mile average, with aid station cutoffs along the way to keep runners on pace. No elevation gain figure is published, so plan around the technical footing and the cutoff pace rather than a specific vert number.
The official race page does not publish an elevation gain figure for the 50K, Half Marathon, or 5 Mile. What is confirmed is that all three distances run along the spine of scenic Moscow Mountain on mostly technical singletrack, with the organizers themselves describing it as "serious up, serious down, serious gorgeous." Expect real, sustained climbing even without a stated number.
With frequent aid station stops on the 50K and a 10-hour window to cover technical Palouse singletrack, aim for roughly 60 to 90 grams of carbohydrate per hour and sodium in the 300 to 700 mg per liter range. The Half Marathon has water stops at miles 5.5, 9.5, and 10.75, and the 5 Mile has one at mile 3, so plan your own carry between those points.

The 50K has a 10-hour overall cutoff, which works out to about 18.66 minutes per mile average pace. The race also enforces aid station cutoffs along the way, both to keep runners on a pace that can finish and to let volunteers sweep and take down the course before the end of the day, so build real margin rather than pacing to the average exactly.
All three distances run along the spine of Moscow Mountain on trail described by the club as mostly technical singletrack with some fast logging roads mixed in. The 50K route is designed to rarely repeat terrain, giving a full tour of what Moscow Mountain has to offer rather than looping the same short section. Come prepared for real technical footing, not a groomed path.
The 5 Mile and Half Marathon give newer trail runners a manageable taste of Moscow Mountain's technical singletrack before stepping up to the 50K. If the 50K is your target first ultra, the 10-hour cutoff gives real room to finish, but this is genuinely rugged terrain run by a small volunteer club since 1978, not a groomed, beginner-smoothed course, so come with technical trail experience under your belt.
