Early Life and Career
Camille was born on Christmas Day in Norman, OK. Due to body quirks, she adapted a unique running style well suited for ultrarunning. She credits her athletic ability and steely toughness to her Grandpa, who earned two Purple Hearts in World War II, and her Dad, both of whom played college basketball at Oklahoma State University for 3-time Olympic Team Coach, Henry Iba. Hearing stories of her Dad practicing six hours without water, as a 7 year old she would practice basketball without water until she would black out. When she was 17, her family became homeless when they lost their home and possessions in the 1999 Oklahoma tornado outbreak. She started running long on Sundays to celebrate her life. She was a 3-time All-Stater in cross country, 3-time State Champion in track and field, and a valedictorian at Westmoore High School. She accepted academic and athletic scholarships to the University of Tulsa, where she was a top 10 senior and earned a B.S. in Exercise and Sports Science in 2005. In 2007, Camille graduated from Oregon State University with a Masters of Science degree in Exercise and Sports Science. She worked as a Research Assistant in bone imaging/osteoimmunology at the University of Oklahoma Health Sciences Center and has co-authored numerous scientific manuscripts. Her sponsors include Nike, Spartan Race, Coros Global, Unived, and Squirrel's Nut Butter. She is married to and coached by Conor Holt, who helps her manage an online coaching business.

In June 2017, she became only the 3rd American to win the Comrades Marathon, leading from start-to-finish. In a memorable finish, she accidentally stopped at the wrong timing mat after receiving the penultimate baton and rose. A male runner came from behind, tapped her on the shoulder, and pointed that she wasn't done yet. She went into a sprint the final 200m to win. As of October 2019, she has set nine Open American Records and three IAU-recognized Open World Bests.
