Athlete Nutrition Profile - Recreational Distance Runner Alice Rosso
Want to get in touch? Send Claire a message!Welcome to episode 74 of the Eat for Endurance podcast, featuring recreational distance runner and screen writer, Alice Rosso. I love showcasing a variety of voices and have been trying to include more recreational athlete episodes, so I was excited when Alice reached out as a fan of the show who wanted to share her story. We recorded in early August, just after she completed the Speedgoat 50k. Alice talks about growing up in Italy, living and training in her current home of Salt Lake City, her struggles with disordered eating and how it nearly destroyed her relationship with her Italian family, her ongoing work with a Registered Dietitian, her career as a screen writer, and a life-threatening accident she recently had out on the trails.I hope you all enjoy this one, and if any of you would like to be considered for a recreational athlete nutrition profile, please email me at Claire@eatforendurance.com with some details about yourself and why you would like to share your story on the show.Links & Announcements:Follow Alice on Instagram, and follow her cookbook account on InstagramHave a guest or topic request or any other feedback?

Relative Energy Deficiency in Sport with Sports Dietitian Heidi Strickler
Want to get in touch? Send Claire a message!Welcome to Episode 73 of the Eat for Endurance Podcast, featuring fellow Sports Dietitian Heidi Strickler, MS RD CSSD. Heidi is a trail runner and self-proclaimed outdoor junkie based in Seattle. I got a listener request to do a show on relative energy deficiency in sport - also known as RED-S (soon to be REDS) - around the same time I heard Heidi’s interview on the Trail Society podcast, and knew she’d be a great dietitian to tackle this topic with me. I have covered this topic before but it’s been over two years, so it was time to do an updated deep-dive.We cover the basics of REDS including warning signs, the normalization of disordered eating especially among endurance athletes, intentional versus unintentional under-fueling, the importance of nutrient timing versus end of day nutrient adequacy, practical advice on how to make sure you’re eating enough and not just relying on hunger cues, menstrual dysfunction, what treatment to regain a period may look like, and SO much more. Please note - just like eating disorders do not have a specific "look," underfueled athletes may or may not show the clear warning signs of REDS that we discuss. For example, they may still have a normal period or they may have normal bloodwork. Pay attention to how you feel during the day, your bowel habits, your sleep, your appetite, how you're recovering from workouts, and the overall picture of your eating and training patterns.I hope you enjoy this episode and find it helpful!

Nutrition for Peri- and Postmenopause with Sports Dietitian Dina Griffin
Want to get in touch? Send Claire a message!Welcome to episode 72 of The Eat for Endurance Podcast! Today’s guest is sports dietitian Dina Griffin, MS, RDN, CSSD, CISSN, who I invited on the show to chat about Peri- and Postmenopause nutrition for female athletes. Dina is the Owner and Founder of The Nutrition Mechanic, and she also co-hosts the Inside Sports Nutrition podcast with fellow sports RD, Bob Seebohar. Some of Dina’s specialities include endurance sports nutrition, women’s health and athletes in peri- and postmenopause, so I knew she’d be a great match for this topic!I’m not in perimenopause yet, but I certainly will be at some point in the not-so-distant future, so this topic is of great personal interest to me. Peri- and postmenopause also is so important for us active women to speak openly about. Much more nutrition research is needed in this area, but there are some strategies that we can adopt both before and during perimenopause to mitigate some of the changes that may occur later on. Dina and I go into all the details, but it's worth mentioning that eating ENOUGH everyday is one of the most important nutrition considerations for these phases of life (do you see a common theme here in these episodes?!). I hope you give this one a listen, even if you feel like perimenopause is far away for you, because what you're doing with your nutrition RIGHT NOW will have an impact years down the line. As 53 and 41 year olds, respectively, Dina and I both have a lot to say about nutrition to our younger selves!Thanks Dina for a great chat, and wishing you the best of luck in your upcoming 100 miler!

Fueling for the Long Haul: Sage Canaday’s Plant-Based Journey from Roads to Trails
Want to get in touch? Send Claire a message!Welcome to Episode 71 of the Eat for Endurance Podcast! This week, I’m joined by Sage Canaday, a pro-runner, coach, and plant-based athlete with over 20 years of running experience. Sage is known for his “any surface, any distance” motto, and his impressive career has seen him excel both on the roads and in the mountains. He’s a 2-time US Olympic Trials qualifier in the marathon and has secured top 20 finishes at both the Boston and Chicago Marathons. In 2012, Sage shifted gears to mountain ultra trail running, where he’s earned numerous wins and podium finishes.Raised as a lacto-ovo vegetarian, Sage experimented with including meat, poultry, and fish in his diet at different points in his life. However, he found that this “foreign cuisine” didn’t appeal to him or offer any noticeable performance benefits. After some trial and error, he made the decision to fully embrace a plant-based lifestyle.In this episode, we discuss:Sage’s transition from road racing to ultra-trail runningHis journey to becoming vegan and how it has fueled his athletic successA look at Sage’s typical day of eating and performance nutrition strategiesHow his diet and nutrition approaches have evolved over 20+ years of runningInsights into training, recovery, and fueling for both short and long distancesWe recorded this interview in early June, just as Sage was preparing for a busy summer of training and upcoming races. By the time this episode airs, he’ll be gearing up for TDS by UTMB on August 28th in Chamonix. Best of luck, Sage—we’re cheering for you!Links:Sage’s YouTube Channel: https://www.youtube.com/user/Vo2maxProductionsSage’s coaching business: https://higherrunning.com/Follow Sage on Instagram, Facebook, and TwitterJoin my monthly membership service, Fuel for Life Crew, for just $30/month (cancel anytime)Check out my free nutrition downloadsFill out a new client inquiry form if you’re interested in 1:1 nutrition coachingSupport the podcast with my Skratch affiliate code EATFORENDURANCE20 Join my Patreon community Get in touch at claire@eatforendurance.comMusic Credit: Joseph McDadeDisclaimer – all information provided is for educational and entertainment purposes only and is in no way meant to replace individual medical and nutrition recommendationsSupport the showThanks for listening!

From Biathlons to Ultramarathons: Corrine Malcolm's Evolving Journey in Sport and Nutrition
Want to get in touch? Send Claire a message!Welcome to Episode 70 of the Eat for Endurance Podcast! In this episode, I’m joined by Corrine Malcolm, a professional ultrarunner, coach, co-host of the Trail Society Podcast, and Editor-in-Chief at Freetrail.Corrine’s story is packed with incredible experiences, and even with 90 minutes of conversation, we barely scratched the surface! We dive deep into her background as a high school and collegiate athlete, where she excelled as a Nordic skier and biathlete, all while dipping her toes into the running world. She opens up about her journey through overtraining as a biathlete, the long process of recovering and reclaiming her health, and how her experience chasing the Olympics shaped her mindset when she transitioned into ultrarunning.One part of her journey that really surprised me is that Corrine was “winging it” with her nutrition until just a few years ago! She shares how her approach to fueling has evolved over time and what’s worked (and not worked) for her throughout her career.We also veer off into other aspects of her story that make her journey even more fascinating. I loved hearing her unique perspective, and I think you will too!As a fun update, we recorded this episode on May 31st, and since then, Corrine has had an amazing performance at the Cascade Crest 100, where she placed third! Be sure to check out the Trail Society Podcast to hear more about her experience at that race.A huge congratulations to Corrine on that accomplishment, and thanks for such a fun conversation!Links:Corrine’s Website: https://corrinemalcolm.com/Follow Corrine on Instagram and Twitter (@corrinemalcolm)Get in touch - claire@eatforendurance.com.Join my new monthly membership service, Fuel for Life Crew, for just $30/month (cancel anytime)Check out my free nutrition downloadsFill out a new client inquiry form if you’re interested in 1:1 nutrition coachingSupport the podcast with my Skratch affiliate code EATFORENDURANCE20 Join my Patreon community Music Credit: Joseph McDadeDisclaimer – all information provided is for educational and entertainment purposes only and is in no way meant to replace individual medical and nutrition recommendationsSupport the showThanks for listening!

Today’s topic is Performance Nutrition for Ultrarunners, and features fellow Registered Dietitian and ultrarunner, Julie Shobe MS RD.

Athlete Nutrition Profile: Pro-Trail Runner and Co-Founder of Freetrail, Dylan Bowman
Want to get in touch? Send Claire a message!Welcome to Episode 68 of the Eat for Endurance Podcast, featuring Dylan Bowman, a professional trail runner, co-founder of Freetrail, and host of the Freetrail Podcast.Dylan has had a long and impressive career as a trail and ultra runner, with too many wins and podiums from the past 14 years to mention here. These days, he’s at least as well known for his company Freetrail as he is for his success as a pro-runner. And that’s exactly how I connected with him, as he was providing livestream coverage of the Canyons Endurance Runs with fellow pro-runner and Freetrail team member, Corrine Malcolm. On top of his media company, Dylan became a parent within the last year, which adds yet another dimension to the demands on his time. But that doesn’t mean he’s not still competing - this year, he recommitted to getting back out on the trails and on the racing scene. We had a great chat about how he has been balancing it all, and how for awhile, he had to deprioritize his running. We of course get into the highlights of Dylan’s training and racing nutrition throughout the different stages of his career, and we explore how his diet and performance nutrition have evolved over time. I love that he approaches his fueling strategies not just from the perspective of what works well with his gut, but also thinking about what works with his personality and overall approach to life. Okay, let’s get into it. And just an FYI that this interview was recorded in mid-May. Dylan is now running the Hardrock 100 next week, and we wish him the best of luck!So without further ado, please enjoy my discussion with pro trail runner and co-founder of Freetrail, Dylan Bowman!

Want to get in touch? Send Claire a message!Welcome to Episode 66 of the Eat for Endurance Podcast, featuring Ellie Pell, aka Gazzellie, a semi-professional distance runner and Manager of the Skratch Labs Cafe in Boulder, Colorado. Ellie is probably best known as a trail and ultra runner, with several wins and podiums under her belt, but she also is a fierce road marathoner! She qualified for the Olympic marathon trials in 2019, ran the trials in 2020, and is still feeling the pull of the road marathon while in the thick of training for this year’s Leadville 100. I’m excited to see what she tackles next! Ellie and I had a long chat about so many different things in her life that I won’t even attempt to summarize it here. But suffice to say, her diet and her relationship with food and body have evolved dramatically since she started running in her early 20s. I really appreciated how open she was in sharing the difficult details of her eating disorder history and recovery. We spend a good chunk of time on that, so please skip past that section if you need to do so. There are plenty of other great parts to this interview, and no shortage of laughter! Thanks Ellie for coming on the show - I know it was a dream come true for you (LOL). I wish you all the best in your upcoming races!
