The Voices & Faces of Endurance Planet

Tawnee Gibson, your host and owner of Endurance Planet.

Tawnee Prazak Gibson, MS, CSCS, CISSN, is a holistic health and endurance sports coach, triathlete/multisport athlete, writer, speaker, and the host and owner of Endurance Planet. She has a master’s degree in exercise science, a bachelor’s in journalism, is a certified sports nutritionist (CISSN-ISSN), and certified strength and conditioning coach (CSCS-NSCA).

She’s been involved in the endurance world for more than a decade, and is considered one of today’s leading experts in the field of endurance training, racing, strength training, sports nutrition and athlete wellness. When not podcasting, Tawnee coaches and consults with triathletes and endurance athletes around the globe, using holistic methods to optimize performance and to prevent the “fit but unhealthy” syndrome. Find out more at CoachTawnee.com. In addition to personalized coaching, she runs an inner-circle membership-based website, Life Post Collective, which is home to all her resources and recipes for achieving a healthy, fit lifestyle.

Tawnee became an athlete early on in life, played volleyball in high school, and ultimately took up (and fell in love with) triathlon and endurance sports in her early 20s. She quickly moved up the ranks as a top-rated amateur triathlete with dozens of age-group wins and podium finishes, racing everything from sprint to 70.3s and Ironman. In less than a decade she had She qualified for the Ironman 70.3 World Championships multiple times as well as the Boston Marathon. She also enjoys competitive trail running, mountain biking and stand-up paddleboarding, as well as recreational backpacking, yoga, SCUBA diving, surfing and snowboarding.

Like many female athletes, Tawnee also has faced her share of health struggles behind the scenes. For 10 years while competing she suffered from hypothalamic amenorrhea and disordered eating issues; the latter of which had stuck with her after battling and recovering from anorexia as a college freshman. During this time she also suffered from gut dysbiosis, HPA axis dysfunction, subclinical hypothyroidism, and so on. Ultimately, Tawnee adopted a functional health approach to heal her body and regain optimal health, and with patience+persistence she achieved immense success. Along the way, she even sought out the expertise of many EP guests to help her navigate her recovery and journey to better health. Today she is thriving and is due to give birth to her first child in early 2018.

Tawnee writes about her experiences—everything from race reports to healing her health to her journey into motherhood—on her blog, www.tritawn.com. Follow her on Twitter at @tawneegibson, or Instagram @tawneegibson.

These are Endurance Planet’s “in house” experts who bring a wealth of knowledge to the podcast on a variety of topics relating to endurance sports, health, sports nutrition, diet and overall wellness:

Tim Wagoneer

Tim Waggoner, AKA “Lucho,” the expert voice of “Ask The Coaches” (ATC).

Tim “Lucho” Waggoner, formerly Luchinske, resides in the mountains of Colorado just outside Boulder and is a highly sought-after endurance coach. On Endurance Planet he’s the vastly popular expert and co-host on “Ask the Coaches” (ATC) show. His experience in sport as both a professional triathlete and elite ultrarunner brings an incredible wealth of knowledge to the show.

Lucho started running at the age of 10 and went on to multiple Kansas state track and field championships and was a two time All-American in college. He decided to drop out after two years and travel eventually settling in the U.S. Virgin Islands where he lived for four years. Tired of the party lifestyle, he quit smoking and entered his first triathlon and placed third. Fast forward, and four years later he placed 16th overall at the Ironman World Championships in Kona, Hawaii, and was the top amateur.

After 15 Ironmans and beginning a family, Lucho switched to running. He ran 2:41 in his first marathon and then 2:30 in his second. Eventually, Lucho and his wife moved up to 8,200ft altitude in the mountains, and this led him to try ultrarunning. In his first race, a 50-mile trail race, he won and broke the course record. He then went on to place 6th at the Leadville 100—his 4th ever ultra. To top it off, Lucho was the overall winner of the Leadman series in 2012, which includes all of the Leadville races. He now spends most his time raising his two sons, coaching athletes, and training for master’s track & field racing.

He also (sometimes) has a badass beard and occasionally blogs words of wisdom at joghard.blogspot.com.

Julie McCloskey is a Registered Holistic Nutrition Coach (RHN) based out of Missoula, MT, who is the featured expert on our Holistic Performance Nutrition podcast series.

Julie McCloskey is aRegistered Holistic Nutrition Coach (RHN) based out of Missoula, MT. After living in upstate New York through college, she moved out West and fell in love with the mountain life. She studied Holistic Nutrition in Vancouver, BC, and now runs her own Nutrition Coaching Business, Wild and Well. Specializing in gut health, inflammation, and hormones, Julie’s passion is helping people regain balance, increase energy, and optimize daily performance through nutrition and lifestyle strategies.

An athlete and competitor since an early age, Julie was ‘that girl’ on the all-boys teams. She played basketball and ran cross-country and track, but soccer was always her love. At the collegiate level, she played soccer and ran track while obtaining her BS in Marketing. After college, Julie began to run longer distances, thus inspiring a curiosity for performance nutrition and recovery tactics. She moved to Jackson Hole where she fell in love with trail running and road biking. Julie races every so often, always drawn to the dirt paths that go straight up, but is 100% intrinsically motivated by the connection with nature and passion to push limits. Over a few years, and with the guidance of many podcasts and books, she slowly moved from junk food to real food, and her interest in nutrition became so deep that she packed up her stuff and moved to Vancouver to study Holistic Nutrition full-time.

Julie’s greatest endurance feat was thru-hiking the Pacific Crest Trail in 2016, which entailed 5 months of hiking 25-35 miles a day for a total of 2,650 miles on the trail that goes from Mexico to Canada. The PCT took its toll and Julie’s still on her own health-recovery journey, which she openly talks about on the podcast.

Dr. Tamsin Lewis is UK-based former professional triathlete, Ironman champion and functional medical doctor. Tamsin’s passion and ‘raison d’être’ is to empower other people to redefine the way they think about health, and find their own journey towards optimal wellness. She qualified with honours in Medicine & Surgery at Kings College London in 2004 intercalating a BSc in NeuroScience and was awarded MRCPsych from the Royal College of Psychiatrists in 2009. She has since trained in a functional medicine approach incorporating advanced nutritional principles and appropriate use of bio-identical hormones. Tamsin practices integrative and lifestyle medicine. Helping clients to redefine their health and discover their true potential. Her main interest is in optimization of healthy hormonal function and recovery from the ‘burnout’ continuum. She works with busy, high achieving clients to improve their resilience and performance with a focus on healthy longevity.

In her youth, Tamsin struggled with disordered eating/dysfunctional mood and addictive behaviours, which attracted a variety of conventional diagnoses and attempts to treat with pharmaceuticals. At no point was there an attempt to address the underlying cause. “Your family has the measles – you have the rash,” spoken by a doctor, resonated profoundly to the 11-year-old Tamsin; yet, no effective system was in place to help navigate what this actually meant. The behavioral and self-destructive symptoms were reflective of an environment which was unstable and traumatic and hence served a protective yet ultimately pathological role. Tamsin had a realization that we trust doctors and a healthcare system to fix disease yet they seemed ill-equipped to do so when the boundaries of disease are a little blurred–not fitting in neat diagnostic clusters–which resulted in a level of deep frustration within her, but spurred on an inherent desire to seek an alternative and solution. In her final year of medical school Tamsin spent three days in a coma after a severe head injury following as skiing accident. Her parents were told she may not ever pull through. But she did. During her time in med school she also began competing in triathlons, and found that her performance improved in direct correlation with the degree to which she optimized key bio-markers through lifestyle, nutrition, supplement and training adjustments.

Tamsin spent four years as an elite GB triathlete following success as an amateur. In 2014 she won Ironman UK in her first attempt at this distance, having never run a marathon prior. Genes load the Gun. Environment pulls the trigger. Tamsin’s father was a former professional cyclist – completing the Tour De France three times and a 5-time British Road Race Champion. Once Tamsin’s physiological health improved she was able to maximize her genetic potential and success as an athlete ensued.

Spurred on her own success and pressure from peers to share her remarkable story of overcoming adversity Tamsin founded curoseven.com in 2013. This began as a performance optimization and proactive health analysis consultancy. The business model has since evolved and been refined as a result of client feedback and increasing demand, the result of which is Fibr Health and its extraordinary Collaborative Team. Follow Tamsin on Twitter at @SportieDoc.
