One of the top ultramarathons on the race calendar took place this weekend in the Marin Headlands just north of San Francisco. The North Face Endurance Challenge Championships, with a $10,000 prize for the 50-mile winner, welcomed many elite trail runners to take on its challenging, yet breathtaking course in the Bay Area.
The 50-miler winners were Zach Miller (6:12:37) and Megan Kimmel (7:13:52).
