Biography
About Katelyn Runck
Katelyn Runck, a 34-year-old athlete and entrepreneur born in Fargo, North Dakota, has built a career that spans fitness, beauty, and influence. She stands 5'10" with an athletic build, brown hair, and brown eyes, and her journey from a struggling runway model to a national fitness pro is anything but typical. Katelyn grew up on a farm as the youngest of four children, and that Midwestern upbringing kept her grounded. She initially pursued fashion modeling in Chicago, completing high school online, but the industry pushed her to extremes. At one point she weighed only 90 pounds at 5'10" and faced serious health battles, including hospitalization for heart failure, liver issues, and an overdose. It took inpatient treatment and a long recovery for her to turn her life around.
After returning home, Katelyn earned certifications in personal training and nutrition through ACE, and she became a licensed yoga instructor with a RYT 200 credential from the Yoga Alliance. She also received her CNA and Medical Aesthetic license, and she opened a wellness boutique and medical aesthetic clinic called Lifestyle Savvy in Fargo, serving clients for over five years with services like laser enhancements, chemical peels, and facials. Her time in the beauty industry, however, led her to a deeper realization: she needed to care for her inner self as much as her outward appearance. Katelyn rebuilt her metabolism by balancing macronutrients, adopted focused workouts, and embraced yoga. For the first time in a decade, she felt healthy and strong.
The turning point in her fitness career came when she entered the competition world. She started in NPC Bodybuilding and later moved to the World Beauty Fitness & Fashion (WBFF) show. In November 2017, at her first WBFF competition in Miami, she placed in the Fitness Diva category and earned her WBFF Fitness Pro Card. Since then she has been a sponsored athlete, eligible to compete professionally. Her social media presence grew quickly, with over one million followers added organically in a single year during 2018. That opening led her to return to modeling, but this time as a commercial and fitness model, not a "skinny agency model." She relocated to Los Angeles to work full time as an influencer, model, and online coach, and she now motivates others to pursue a balanced lifestyle.
Katelyn's mission is to empower others with the same confidence and strength she found. She coaches clients who want to build muscle, lose weight, compete in WBFF or NPC, or simply feel better about themselves. She emphasizes that fitness is a lifelong lifestyle, not a quick fix. Her Instagram following has grown to 2.4 million, and she uses that platform to share her story and her coaching. From her farm roots to the fashion runways and now to the fitness world, Katelyn's path has been marked by resilience and a determination to help others. She believes anything is possible with hard work and self-belief, and her journey proves that change is within reach.
