Eyes on the Trail. Eyes on UTMB.
Rudy Project is the Official Eyewear of the UTMB World Series — built for changing light, technical terrain, and the world's most demanding trails.
Rudy Project becomes the Official Eyewear of the UTMB World Series — the most iconic global circuit dedicated to trail running. This partnership unites
performance eyewear, outdoor innovation, and a shared passion for
endurance, mountains, and exploration.
From exposed alpine ridges to shadowed forest trails, UTMB represents the ultimate proving ground where clarity, protection, and focus aren't optional — they're essential. Rudy Project brings its decades of optical engineering directly to the world's most demanding terrain.
Together, these two icons of outdoor performance share a belief: that the right gear doesn't just support performance — it elevates it.
Trail running environments change constantly — and so does the light. From blazing ridgeline exposures to the sudden darkness of forest canopies, every kilometer demands a different kind of visual readiness. Reading the trail clearly isn't a luxury. It's a necessity.
Ridgelines
Bright, exposed, and unrelenting. High-altitude ridges offer no shelter from direct sunlight,
demanding maximum glare protection and
optical precision.
Forests
Sudden shadows and reduced contrast challenge depth perception. Lenses must adapt instantly as runners move from open skies into dense canopy.
Technical Trails
Fast decisions on complex terrain. Rocky
descents require split-second reactions — and the visual clarity to read every obstacle before it arrives.
On the Trail, Light is Never the Same
Sunlight, forest cover, and sudden terrain transitions constantly reshape the way runners perceive the trail ahead. Every step moves through a different luminous reality — from the glare of open ridges to the deep shadow of wooded descents.
Seeing clearly is not just about comfort. It means reacting faster, maintaining focus, and navigating the terrain with absolute confidence. When vision falters, performance suffers. When vision is sharp, the trail opens up.
Vision Changes Everything
When trail conditions shift between blazing sunlight and deep shadow, visual clarity becomes the difference between confidence and hesitation. Rudy Project eyewear is engineered specifically for these moments — the transitions, the technical passages, the long hours on demanding terrain.
Designed for trail runners who refuse to compromise, every frame balances optical precision with the durability required by mountain environments. From the first climb to the final descent, performance eyewear becomes an extension of the athlete.
MAde for changing light
ImpactX Laser Purple HDR lenses and ImpactX Red HDR represent a breakthrough in trail running optics — photochromic technology engineered to adapt in real time to shifting environments, while actively enhancing contrast in the shadowed terrain where most runners struggle most.
Photochromic Adaptation
Lenses react dynamically to changing UV and light conditions, automatically adjusting tint to match the environment — no manual intervention required.
HDR Contrast Enhancement
Purple tint technology amplifies contrast in low-light and shadowed conditions, revealing trail detail that standard lenses miss.
ImpactX Durability
ImpactX lenses combine impact resistance with optical clarity — built to withstand the demands of alpine environments and technical terrain.
When trail running moves into open alpine terrain, light conditions can become intense and highly reflective. Rudy Project RP Optics Multilaser lenses provide exceptional visual comfort in bright environments, ideal for exposed ridgelines, high-altitude trails, and long efforts under strong sunlight.
The multilayer mirror treatment reduces glare, maintaining clear, natural vision and helping runners stay focused even in the most demanding light. All RP Optics lenses offer maximum protection and visual precision, completely neutralizing UV radiation up to 400 nm while preserving natural color perception.
The collaboration between Rudy Project and UTMB World Series is built on a foundation of shared values: innovation, sustainability, performance, and a deep, authentic connection to the global trail running community. This is not simply a sponsorship — it is a meeting of two brands that define their respective worlds.
Together, they celebrate the spirit of exploration, the discipline of endurance, and an unwavering respect for the mountain environments where athletes push the boundaries of what is humanly possible. Every race, every ridge, every finish line is a testament to that shared belief.
Alpine Spirit
A shared passion for high-altitude adventure and mountain exploration.
Sustainability
Committed to protecting the natural environments that define trail running.
Community
Rooted in a global culture of athletes, explorers, and outdoor enthusiasts.
Explore a curated selection of Rudy Project eyewear purpose-built for trail running — designed to perform in changing light, engineered for technical trails, and refined for the demands of long-distance mountain efforts.
Photochromic Trail Series
ImpactX HDR lenses adapt automatically to changing light conditions on the trail. The photochromic technology reacts instantly to variations in light, while HDR enhancement improves contrast in shadowed terrain. The result is clearer trail readability, helping runners better identify rocks, roots and technical sections while maintaining focus and confidence on every step.
The Static Lens Option
Discover the excellence of RP Optics static lenses, delivering outstanding optical clarity and UV400 protection. The multilayer mirror treatment dramatically reduces glare while preserving natural color perception. The ideal choice for tackling constant and intense light conditions with impeccable vision.
Long-Distance Comfort
Engineered for the long hours. Lightweight frames and anti-slip grip keep focus sharp from the first climb to the final descent.
Before and After the Race
Designed for life beyond the trail,
Rudy Project Active Lifestyle eyewear brings the spirit of UTMB into everyday moments.
Lightweight, comfortable and effortlessly versatile, these glasses are perfect for the hours before the start line and the well-earned recovery after the race. From the village atmosphere to post-run relaxation.
