The sisters occasionally modeled before moving to Mexico City in 1965, where they began modeling full-time, eventually opening a school, agency and design boutique. Warren began performing under the stage nameBarbara Angely,[4] abruptly ending that career out of dissatisfaction with a jet-set lifestyle. Warren eventually married importer Armando Alvarez, which led to a four-year separation from her sister.
Warren's family in 1980 moved to Brownsville, Texas. In 1983, Warren began running recreationally. By 1985, Drake and her family had moved to San Diego, California. Warren, with her family, followed her sister and relocated to San Diego later the same year.
Calling themselves "The Twin Team,"[5] the sisters began participating in a number of endurance sports, including their first standard triathlon in 1987 and their first Ironman Triathlon in 1988. All told, Warren completed 13 Ford Ironman Triathlon World Championship in Hawaii, winning her age group in the 2003 Ironman Kona.[6] Warren and her sister were profiled in Reckless: The Outrageous Lives of Nine Kick-Ass Women.[7]
In the early 1990s, she met triathlete Tom Warren, who won the second Ironman competition in 1979, and the two married in 1995.[3]
Warren self-published three motivational books, Unleash the Power to Complete Your Goals,Become Exceptional, and Do What You Don't Want to Do.[8]
