Who's going to Palo Duro Trail Run?

Free. You can start with nothing.

Free, and always will be. NavRun makes money from race-day planning for runners who want it, never from this. Ultras change constantly, sometimes the morning of. Always confirm with the race director and the official website before you rely on anything here.

The course

Where it goes loop · 6 aid stations

One lap of the canyon loop from the Mack Dick Pavilion, the same loop the 50K runs twice and the 50 Mile runs three times. It starts at 7:20 am in a wave behind the 50 Mile and 50K. Finishers get a Palo Duro hat. The course closes at 7:00 pm.

Rock Garden Trail and the Comanche trails are the most technical part of the loop: short steep ascents and descents, loose rock, and drop offs close to the trail. The Hackberry Spur and parts of Paseo del Rio are very sandy, and most of the trails are hard packed singletrack. Mid October in the canyon can be freezing at the start and over 100 degrees in the afternoon.

The race

What this one is

The Palo Duro Trail Run is run on the floor of Palo Duro Canyon State Park in the Texas Panhandle, the second largest canyon in the United States. It is a loop course from the Mack Dick Pavilion: 50 miles is three laps, the 50K is two and a 25K is one, so you come back past your crew every lap and see other runners most of the day. Underfoot it runs from rolling singletrack to sand and rock, with short steep technical climbs and descents. Mid October in the canyon can be freezing at the start and over 100 degrees by the afternoon.

The race was started by Red Spicer as a road race and became a trail run. By 2003 it was in its 18th year, with a 20K, a 50K and a 50 mile on a 12.5 mile loop and nearly 200 runners on the line before dawn. The distances now are 25K, 50K and 50 miles on a 15.5 mile loop. From 2024 the direction alternates, east in even years and west in odd, and west is the way the course has historically been run. The 2025 running was the race's 40th year.
