Stretching across the raw wilderness of Alta, Wyoming, the Pierre's Hole 50/100 Marathon invites runners and hikers to meet a landscape fiercely itself. This event tests endurance with two distance options—50 miles or 100 miles—each carving through forested trails, rocky ascents, and open ridgelines. Expect an elevation gain topping 15,000 feet on the 100-mile course, where rivers dare you to keep pace and ancient pines whisper encouragement.

The terrain varies from packed dirt paths in stretches to jagged, technical rocks that force scrutiny underfoot. The route navigates through sections of soft pine needles, creating a cushion for legs while demanding sensitivity to hidden roots beneath. Views unfold gradually, from tight tree-lined corridors to expansive meadows framed by the Teton Range.

Hydration is paramount. The high elevation—starting near 6,300 feet and climbing beyond 9,000 feet—pushes the body to adapt quickly. Water stations are spaced but sporadic along the course, so carrying a hydration pack or bottles is non-negotiable. Footwear should combine durability with agility; trail runners with reinforced toe protection and reliable tread will fare best.

Timing your adventure during mid-July to early August usually ensures the trail is clear of snow, with days long enough to cover extensive mileage under mostly stable weather. Mornings bring crisp coolness that shifts to warm afternoons, sparking runs and hikes to maintain a steady rhythm. Night sections offer a different challenge: shadows deepen, and the landscape assumes a brooding personality that demands respect.

Prepare for more than physical stamina—the psychological edge matters as much. The terrain is not merely an obstacle; it is an active presence, sometimes resisting forward movement with steep ascents or unpredictable footing. But meet it with readiness and it rewards you with glimpses of wildlife like elk grazing quietly or hawks circling overhead.

Understanding the route's demands is key: pacing strategies, gear selection, and nutrition plans will define success. Whether tackling the 50-mile challenge or pushing through the 100, consider this marathon a conversation with a landscape that will challenge your limits and, if listened to, guide you firmly forward.
