Looking to level up your race calendar with unique experiences you won’t find anywhere else? These standout trail and ultra events aren’t just about the miles — they’re full-on experiences that deliver jaw-dropping scenery, unforgettable terrain, and stories you’ll be telling for years. From high-alpine ridgelines in Montana to desert moonlight miles in Arizona, each of these races brings its own unique flavor of grit and beauty. 

Whether you’re chasing a PR, a belt buckle, or just a serious dose of adventure, here are four woah-worthy races to add to your bucket list.

🌄 The Rut (Big Sky, Montana)

Every September, mountain runners of all kinds descend on Big Sky for The Rut, a notoriously technical 50-kilometer race (plus 21k and 11k options) through Montana’s wild alpine terrain. The course includes nearly 10,000 feet of elevation gain, with rugged climbs, loose scree, and exposed ridgelines — including a dramatic summit push up Lone Peak at 11,166 feet. Scenic highlights include panoramic views over the Gallatin Range, high-alpine meadows, and vertical cliff bands. The terrain is raw and exhilarating, with steep scrambles and narrow ledges offering big-mountain thrills. This one’s not for the faint of heart, but the vistas are worth every tough step.

Recommended Gear: Smartwool Active Ultralite Short Sleeve Shirt

Designed with freedom of movement and natural temperature regulation in mind, the Active Ultralite Short Sleeve Shirt is a top pick for long-distance runners. The blended Merino and Tencel performance fabric helps runners stay cool thanks to the natural fiber’s breathability, moisture-wicking, and odor resistance. A regular fit gives you mile-after-mile comfort, while flat lock seams reduce chafing for a smooth ride.

🌵 Javelina 100 Mile (Fort McDowell, Arizona)

Desert meets disco at the Javelina 100 Mile, held each October just outside of Phoenix in Arizona’s McDowell Mountain Regional Park. Known for its party vibe and costumed runners, this 100-mile, multi-loop race still packs a serious challenge — heat, dust, and a deceptively rolling course with more than 6,000 feet of elevation gain. Racers wind through cactus-dotted desert, sandy washes, and rocky singletrack under open skies, with moonlit night loops creating an otherworldly atmosphere. Then, runners pass through aid stations, and the start-finish of each loop, and experience the party atmosphere for which this event is known. It’s equal parts endurance and celebration, blending Sonoran scenery with ultrarunning grit.

Recommended Gear: Smartwool Active Lined Shorts

Built for movement, comfort, and performance on the trail, the Active Lined Shorts are a go-to for anyone logging training miles or racing technical terrain. Featuring a lightweight, recycled stretch shell and a super-soft Merino Sport brief liner, these shorts deliver breathable support and moisture management during high-output activities. An adjustable drawcord waist helps keep the shorts in place while offering a relaxed fit and trail-ready durability. Available in 7-inch and 5-inch models for men and 4-inch and 3-inch styles for women.

🏞 Wild Wild West Marathon and Ultra (Lone Pine, California)

Set beneath the snowcapped spires of Mount Whitney, the Wild Wild West Marathon and Ultra is a high-desert race full of cinematic scenery. Held in the fall, the course traverses dirt roads, sagebrush flats, pine-lined creeks, and canyon climbs in the Eastern Sierra Nevada. Runners gain between 2,200 and 7,700 feet, depending on which race distance they undertake, with vistas of the Sierra Crest, Alabama Hills, and Owens Valley throughout. The setting is rugged, remote, and expansive — perfect for runners chasing altitude and open-space solitude.

Recommended Gear: Smartwool Trail Run Crew Socks

The Trail Run Crew Socks combine comfort, durability, and performance. Zoned cushioning helps absorb impact on uneven terrain, while the crew height offers added protection from trail debris. Thanks to a breathable Merino wool blend, these socks manage moisture and resist odor even during long efforts. Reinforced construction boosts longevity, and the snug, stay-put fit means fewer distractions — just you, your stride, and the trail ahead.

🌼 Wildflower Trail Races (Bastrop, Texas)

Few races capture the spirit of spring like the Wildflower Trail Races in the Texas Hill Country. Held each April, this trail event offers multiple distances, including a half marathon and 50k, set against a backdrop of rolling limestone hills, oak woodlands, and vibrant wildflower fields. Runners tackle rocky terrain, short steep climbs, and open ridgelines with sweeping views of the surrounding countryside. What makes this race truly stand out is its seasonal timing — expect to see bluebonnets, Indian paintbrush, and a colorful display of Texas wildflowers lining the route. With warm hospitality, rugged trails, and a laid-back post-race vibe, this event is a perfect mix of challenge and charm.

Recommended Gear: Smartwool Run Compression Over the Calf Socks

The Run Compression Over the Calf Socks support runners through long miles, with graduated compression that helps improve circulation and reduce muscle fatigue — ideal for distance runs or recovery. A Merino wool blend keeps things breathable and dry while naturally resisting odor. Designed to stay in place without slipping or bunching, these socks deliver performance-ready comfort whether you’re logging training miles or recovering after race day.
