Health and fitness expert Mark Sisson is the bestselling author of The Primal Blueprint and several other Primal Blueprint-branded books, and one of the leading voices of the burgeoning Evolutionary Health Movement. His blog, MarksDailyApple.com, has paved the way for Primal enthusiasts to challenge conventional wisdom's diet and exercise principles and take personal responsibility for their health and well-being. From its humble - and controversial - beginnings in 2006, Mark's Daily Apple has grown into one of the highest-ranked health information resources on the Internet, with some 3 million unique visitors each month. Mark, 62, has a BA in biology from Williams College and is a former world-class endurance athlete, with a 2:18 marathon and a fourth-place finish in the Hawaii Ironman World Triathlon Championships to his credit.
Today, Mark directs his competitive energies into high-stakes Ultimate Frisbee tournaments against competitors decades younger. Besides blogging daily, Mark conducts seminars on the Primal Blueprint way of life and hosted 9 multi-day total immersion retreats called PrimalCon at locations across America and in Mexico from 2010-2014. He operates Primal Blueprint Publishing in Malibu, CA, publishing his own titles as well as work from other authors promoting ancestral health principles. Mark is married to Carrie and they have two children.
