Endurance running is brutal enough as it is, but The North Face athlete Hillary Allen has had a tougher road in the sport than most. Blasting onto the trail scene in 2014 as the US Skyrunning World Champion (only two years after she ran her first marathon), Allen tackled a number of big-name events around the world, placing in the Top 3 in the Skyrunner World Series for the next three years. She not only took numerous golds in endurance races from Italy to Utah to Portugal, but set over half a dozen FKTs, including course records for the Speedgoat 50K and the TNF Cortina Trail (48km). Along the way, the 32-year-old earned the moniker “Hillygoat” due to her reputation for charging burly, technical mountain terrain at breakneck speeds.
