Courtney Dauwalter is one of America’s top endurance runners, with numerous ultra-trail wins and records to her name. In 2018 alone, she won the Sean O’Brien 100K in California in February, Ultra Trail Mount Fuji 100 in April, the iconic Western States Endurance Run in June, and our very own Squamish 50 in August.
In September, Dauwalter set out on the Tahoe 200, a 200-mile (320K) race with 12,800m of elevation change, with the goal of winning it in 48 hours. (That was 10 hours faster than the existing course record of 58 hours, 29 minutes.) She ran up a 1.5-hour lead over Colorado ultrarunner Kyle Curtin, holding him off through almost two full days and nights of running.
