and has been featured in TIME, Newsweek, People, GQ, The New York Times, USA TODAY, and The Washington Post, among others. Karnazes won Competitor magazine's "Endurance Athlete of the Year" award three times, and also earned ESPN's ESPY award. The "Ultra Marathon Man" episode of Stan Lee's Superhumans documentary television series maintained that Karnazes is able to reduce the build-up of lactic acid over long periods of time. Karnazes also ascribes his endurance feats to an ability to remain under his lactate threshold – his body's ability to clear lactate from his blood and convert it to energy. Among his training tips is to consume sardines for protein. Personal life In his memoir, Karnazes explains he was twice expelled for attending school while drunk. Karnazes stated that he quit drinking while at Cal Poly, after the death of his sister. Karnazes attended California Polytechnic State University at San Luis Obispo, where his major subject was food science technology. He attended graduate school at the same institution, ending up as the class valedictorian. He paid for his education by obtaining scholarships and grants, and by working at a campus health center. Karnazes then went to the University of San Francisco's McLaren School of Business. He holds graduate degrees in Science and Business. Karnazes met his wife Julie in 9th grade at San Clemente High School. Karnazes' children accompanied their father for much of his run of 50 marathons in 50 states, as they were home-schooled at the time. Karnazes lives in Ross, California. On August 12, 2022, Karnazes claimed in an Instagram video to have been attacked by a coyote during a race in the Marin Headlands. National Park Service rangers noted that his story did not match biologist's understanding of coyote behavior, even among those habituated to humans, and that his injuries appeared to be sustained from a fall, rather than an animal attack.
