The Teeny-Way 50K winds through wild, rugged Washington mountains. Expect rocky, uneven trails, long steep hills, and long stretches between aid stations. The trail is primarily single track with occasional smoother sections. Weather can vary dramatically from warm days to freezing nights, with potential for rain, snow, wind, or lightning storms. Wildlife encounters, though unlikely, are possible including rattlesnakes, black bears, cougars, and wolves.

Aid stations are spaced roughly 8 to 10.6 miles apart and are fully stocked with water, electrolytes, gels, fruit, sandwiches, and other special treats. They are accessible only by off-road vehicle and are not crew-accessible.
