Marissa DeMercurio lives in Arvada, Colorado. On December 6, 2014 she finished the North Face Endurance Challenge 50k in San Francisco, California and became an ultramarathon finisher. Congratulations Marissa!
Fun fact: Marissa carries her favorite hydration fuel with her, because it's highly unlikely she would ever see it at an aid station. It's iced tea and lemonade - an Arnold Palmer!
