The PodiumRunner Endurance Podcast is hosted by Ian Sharman, a professional ultra runner and coach with over 200 marathons or ultra finishes and more than 50 wins (www.sharmanultra.com, twitter.com/sharmanian). We discuss training and racing topics with leading sports scientists and how to practically apply research findings for marathoners and ultra runners. Episode 7: Tina Muir and Relative Energy Deficiency in Sport (RED-S) Tina Muir who is a British International elite runner living in St Louis, Missouri, a keynote speaker, and host of the Running For Real Podcast, which has amassed three and a half million downloads. Tina founded Running For Real in 2017 as a support network and community for runners to have a place to share struggles and empower other runners. This show delves into Tina’s experience as an elite, 2:36 marathoner, in particular: - Not having a period for nine years, called amenorrhea, then realizing she had disordered eating. - The broader concept of Relative Energy Deficiency in Sport (RED-S), plus the warning signs and what to do about it. This is especially relevant for female athletes, but the over-training and under-eating elements apply to everyone. - Life beyond competitive road running, including trails and adventure racing. - Her business, Running For Real, and her podcast. Tina’s on www.Twitter.com/tinamuir, www.Instagram.com/tinamuir88 and her Facebook group is very active, called Running for Real (like the podcast). We mention a couple of resources in our discussion: her podcast with Dr. Jennifer Gaudiani (https://tinamuir.com/jennifer-gaudiani/) and her nutrition page (https://tinamuir.com/running-podcast-nutrition/).
