On Dec. 3, Zach Miller and Hayden Hawks went out like gangbusters at the start of The North Face Endurance Challenge 50-Mile Championships in the Marin Headlands north of San Francisco. Those who witnessed the race were left in stunned awe at the effort those two runners put out from start to finish. Miller, a Nike-sponsored runner, wound up winning the race in a course-record time of 5 hours, 56 minutes, 3 seconds, finishing the final 5K in under 16 minutes. Hawks, a Hoka athlete, was equally impressive, finishing about 2 minutes later, also under the previous course record. (Miller’s time equates to 7:07/mile pace—on a extremely hilly course almost entirely on trails.) Sure, there was a $10,000 first-place cash prize on the line, but you get the feeling these two guys would race this hard for $10. Check out this amazing video from Jamil Coury, Michael Carson and Billy Yang, which captures the action, intensity and drama of the race in vivid detail as Miller and Hawks take ultrarunning to the next level.
