Christine Schirtzinger is an endurance coach, registered nurse, and lifelong athlete who believes that fitness and health should build on each other—not compete with each other. For more than 15 years, she has coached hundreds of athletes, from people taking their first steps into endurance sport to elite athletes pursuing personal bests and championship-level goals.

Her coaching philosophy starts with the individual. Rather than simply prescribing workouts or following a generic training plan, Christine looks at the whole athlete—their experience, health, lifestyle, available time, strengths, limitations, and goals. Training may integrate running, cycling, swimming, strength, recovery, nutrition, and performance data, but the objective is always the same: help athletes become stronger and more capable while building a relationship with sport that can last a lifetime.

Christine brings an unusual combination of experience to coaching. Her background as a critical care registered nurse gives her a deep understanding of physiology, health, recovery, and the importance of looking beyond performance alone. She also uses data and technology—including heart rate, power, and physiological testing—to help athletes understand why they are training a certain way, not simply what workout comes next.

She holds advanced coaching certifications from USA Triathlon, USA Cycling, USA Masters Swimming, MAF, TrainingPeaks, and Swim Speed Secrets. Her work in sports technology has included serving as Director of Coaching for Tyme Wear, participating in product development and beta testing for endurance technologies, and helping translate complex performance science into information athletes can actually use.

Community has also been central to Christine’s career. She founded Girls Gone Tri, a free women’s triathlon community that grew to more than 200 athletes and was recognized by IRONMAN as a model for bringing new women into the sport. She also co-founded Valley Velo, a cycling club that welcomed riders across multiple ability levels. Both grew from a belief that sport should feel accessible and that athletes often accomplish more when they feel supported by the people around them.

Christine understands the athlete experience personally as well. She has spent nearly three decades in endurance sport, completed more than 75 running and triathlon events, raced more than 20 IRONMAN 70.3s, qualified multiple times for the Boston Marathon, and qualified six times for the IRONMAN 70.3 World Championship.

She is currently completing an MBA in Data Analytics with a 4.0 GPA, continuing a career-long commitment to learning, questioning, and finding better ways to help athletes succeed.

Whether the goal is completing a first race, returning to running after years away, setting a personal best, or simply becoming healthier and stronger for the decades ahead, Christine’s goal is to meet athletes where they are—and help them discover where they can go.
