Breaking Down to Break Through: How Julie Rembold Overcame 4 Years of Health Issues to Return to Elite Running
In this compelling episode of DFW Running Talk, host Chris Detzel sits down with Julie Rembold for an in-depth look at one of the most remarkable running journeys you'll ever hear. Julie's story begins at age 37 when she started marathon training with virtually no running background, quickly dropping from a 3:47 debut at Houston Marathon to a 2:51 Boston qualifier in just two years.
But this isn't just a story about fast times. Julie's journey takes a dramatic turn when mysterious health issues began affecting her performance and quality of life. Despite running impressive marathon times, she experienced symptoms ranging from severe fatigue and heart rate irregularities to neurological issues that made her leg feel "disconnected" during runs. For four years, she battled through these challenges while doctors struggled to provide answers.
What makes Julie's story truly extraordinary is how she took her health into her own hands. Using her engineering background and relentless research, she discovered that mineral imbalances—particularly copper and iron deficiency stemming from five pregnancies and breastfeeding—were at the root of her problems. Her recovery involved switching from synthetic supplements to natural nutrition sources, ultimately healing her body completely.
Julie opens up about the challenges of balancing marathon training with raising five children, the support system that made her running possible, and how her husband's leukemia diagnosis affected her first marathon. She also discusses her transition into health coaching, helping others who face similar struggles.
Now at 45, Julie has returned to form with recent marathons under 3 hours and ambitious goals ahead, including a 2:45 target at the Marathon Project in December. Her story is a testament to the power of listening to your body, advocating for your health, and never giving up on your goals.
This episode offers valuable insights for runners dealing with unexplained performance issues, parents trying to balance training with family life, and anyone interested in the connection between nutrition and athletic performance.

Host
Chris Detzel
Chris Detzel is the passionate host and creator of "DFW Running Talk," the premier podcast dedicated to showcasing the vibrant running community across the Dallas-Fort Worth metroplex. Since launching the show in October 2024, Chris has established himself as a central voice in North Texas running culture, conducting in-depth conversations with elite athletes, coaches, race directors, and inspiring everyday runners who define the region's diverse running scene. As both interviewer and active participant in the DFW running community, Chris brings an authentic perspective shaped by years of personal running experience. While he describes himself as primarily a half marathon runner rather than a marathoner - citing the extensive training commitment and unpredictability of marathon race day - his deep knowledge of running culture spans the full spectrum from 5Ks to ultramarathons. His preference for half marathons stems from their balance of challenge and accessibility, allowing him to race monthly without the intensive training demands of longer distances. Chris's connection to elite running runs through his family - his wife Lea Ivy is an accomplished marathoner who has completed the Boston Marathon 12 times consecutively, achieving a personal best of 3:14 at age 45. This personal connection to high-level competition, combined with his own running journey, gives Chris unique insight into both the elite and recreational sides of the sport. He often travels to Boston to support Lea's racing and has become part of the broader running community that gathers around major events like the Boston Marathon. Through DFW Running Talk, Chris has created more than just a podcast - he's built a platform that celebrates the depth and diversity of North Texas running talent. His interviews reveal the stories behind local legends, from sub-3:00 marathoners to innovative coaches, from race directors creating memorable experiences to everyday runners achieving extraordinary personal transformations. The show has featured conversations with accomplished athletes like Shantel Cloud (sub-3:00 marathoner), Travis Dowd (Dallas Marathon winner), and Mimi Smith (Olympic Trials competitor), alongside community builders and running industry professionals. What sets Chris apart as a host is his ability to connect with guests on multiple levels - as a fellow runner who understands training cycles and race strategy, as a community member invested in the local running scene, and as a skilled interviewer who draws out both technical insights and personal stories. His approach prioritizes authentic conversation over surface-level inspiration, resulting in episodes that offer genuine value to runners of all levels. Based in the Dallas area, Chris continues to grow DFW Running Talk's reach across multiple platforms including Apple Podcasts, Spotify, Amazon Music, and YouTube, while maintaining strong connections to local running organizations like Dallas Running Club and participating in the broader Texas running community. His work documents and celebrates a running culture that he believes is "way more badass than it has any right to be."
