Brad Kearns is the President of Primal Blueprint Publishing, and has worked closely with Mark Sisson since 2008 on the Primal Blueprint, Primal Blueprint 21-Day Total Body Transformation, Primal Blueprint 90-Day Journal, The Primal Connection, and Primal Endurance. Brad is the director of the Primal Blueprint Expert Certification Program, and host of the Primal Blueprint and Primal Endurance Podcasts.

Prior to joining the Primal team, Brad wrote nine other books on health, fitness, and peak performance for McGraw-Hill and other publishers, including Breakthrough Triathlon Training. Brad competed on the professional triathlon circuit for nine years, where he won 31 events across the globe. Coached by Mark Sisson, Brad was a 2-time US national champion, world duathlon series champion, and the #3 ranked pro triathlete in the world in 1991.

Brad is a longtime coach and speaker in the endurance sports world, known for his humorous but deeply reflective presentation message, and his relaxed and intuitive approach to training. Today Brad's competitive outlet is Speedgolf, where he placed 20th in the 2014 World Professional Speedgolf Championships, shooting 83 while running full speed through a championship course in 51 minutes. To challenge the aging process after turning 50 in 2015, Brad high jumped 5'3" (meeting USA Masters Track&Field All-American standard for age 50-54 category), ran 400 meters in 59 seconds, and repeated his 20th place finish in the World Speedgolf Championships as the second-oldest competitor in the pro field. With continued improvement in high jump and sprinting, he hopes to earn a varsity letter with the local high school track team someday.
