Nike ACG has spent decades chasing the call of the wild — across every surface, in every season, through every condition. Now, in that spirit, Nike ACG is introducing the All Conditions Racing Department: an elite roster of athletes who are dedicated to high-speed pursuits and want to outrun everything.
The All Conditions Racing Department is where Nike ACG gathers the wild, where collective grit builds community, and where identity and performance come to life. Simply put, it’s where the next evolution of Nike ACG begins.
The elite trail runners who comprise the All Conditions Racing Department roster are co-creating the future of trail performance: testing prototypes, providing feedback and breaking things — all in service of Nike ACG’s charge to build better, stronger, faster and wilder gear for the outdoor athlete.
This takes form in innovation that starts on the mountain, flows through the Nike Sport Research Lab, and lands back in the dirt — setting the pace and standing out from the pack.
“Nike ACG believes that life is meant to be unleashed in the wild,” says Scott LeClair, VP/GM, Nike ACG. “From Fastest Known Times to 100-milers, mountain climbs to river crossings, the pursuit of feral dreams fuels everything we do. It’s dirty. It’s hard. It’s gritty. That’s what Nike ACG and our All Conditions Racing Department athletes are getting after.”
From its founding fathers on Hayward Field to its support of alpine trailblazers scaling K2, Nike has demonstrated for more than five decades an unwavering commitment to pushing the limits of human potential, transforming what’s possible for both elite and everyday athletes. Nike ACG was built in that image nearly 40 years ago, applying Nike’s spirit of innovation to serve athletes who test their mettle in the most extreme environments on earth.
The All Conditions Racing Department advances Nike ACG’s legacy of getting wild with Nike outdoor athletes and supporting their dreams, no matter how audacious. This approach reflects what outdoor athletes have long known: Endurance trail running is built on and fueled by an ardent community of barrier-breakers and innovators — from Transgrancanaria to the Western States Endurance Run, Chongli 168 Ultra Trail to the Ultra Trail du Mont Blanc.
“The way Nike ACG is showing up for me and my teammates at races like Western States shows their care and investment in trail,” says Caleb Olson, All Conditions Racing Department athlete and winner of the 2025 Western States Endurance Run. “Whether I’m testing new protos, giving input or planning my next summit, Nike ACG’s support means I can push my limits and redefine what’s possible on the trails.”
