40th Birthday Type 2 Fun - Sean O'Brien Trail Marathon Race Recap
Welcome to Episode 44 of the Eat for Endurance Podcast, highlighting my 40th birthday trail running adventure down in Southern California with my husband, Eric. With all the major marathons happening so close together, I figured it was a perfect time to post our recent experience running 26.2 (well, technically 27+ miles, but hey, that’s a trail marathon for you!).I don’t know how you guys like to travel, but for me the perfect trip includes is a bit of relaxation, plenty of active adventures, and of course, good food. So, when Eric asked me how I wanted to celebrate turning 40 years old (!!!!!) in September, I immediately started to look for trail races, hikes, and whatever else sounded like an epic way to get older. Initially, I was determined to go to the Grand Canyon (never been!) and check the Rim to Rim off my bucket list, but unfortunately we weren’t able to make it happen with childcare. I went back to the drawing board and saw that Sean O’Brien, a classic race down in Malibu Creek State Park, was the day after my birthday, so we signed up for the marathon! They also had a 50k that day (and 50 and 100 milers in October ), but with our less-than-ideal training, and such a difficult course with tons of elevation gain, we knew the marathon would be hard enough. This was my first marathon since running Big Sur back in April 2016, before having kids! I was super excited to get back to the long stuff, and to explore some new trails in my home state. Much like with our Big Basin trail running podcast episode, Eric and I recorded our thoughts before the race while we chilled out in Cambria, a small beach town a couple hours south of Santa Cruz. Then we gave a detailed recap hours after finishing the race, from our Air BnB in Topanga, lying in bed! It was a very challenging but super fun day out, and I highly recommend the race. Very well organized and a beautiful course. I’m hoping it’s my first of many longer trail races in the months and years to come!Thanks for listening, and if you’re interested, Eric made an awesome action camera video documenting the entire thing! I’ll post it on Instagram (@eatforendurance) soon.Hope everyone is enjoying the Fall racing season, and best of luck to all my friends and clients running Chicago and Boston this weekend!Other Announcements:Please show your support by leaving a rating and/or review on iTunes Music Credit: Joseph McDadeHave nutrition questions, a guest or topic request, or any other feedback?

"High Performance Nutrition for Masters Athletes" with Sports Dietitian Lauren Antonucci
In episode 43 of The Eat for Endurance Podcast, I’m joined by Sports Dietitian Lauren Antonucci, RDN, CSSD, CDE, CDN, to dive into Nutrition for Masters Athletes. Lauren was first on the show back in 2019 to discuss fueling young athletes, and now, with the release of her book High Performance Nutrition for Masters Athletes, we’re shifting the focus to athletes aged 35 and up (also known as “Masters Athletes”).Lauren’s book is packed with valuable insights for anyone interested in optimizing their nutrition for better performance, whether you’re in the Masters category or not. It’s a comprehensive resource that combines research-backed advice with practical strategies.Lauren is the Director and Owner of Nutrition Energy, a private practice based in Manhattan. She is a certified specialist in Sports Dietetics, a Certified Diabetes Educator, a busy mom of three, and a lifelong athlete herself, having completed 13 marathons, 3 Ironman triathlons, and numerous other races in running and triathlon.In this episode, we explore topics such as:How what worked for you as a younger athlete might no longer serve you as you ageThe key nutrition changes to make as we get older, supported by the latest researchWhy carbs are crucial for both health and performance, yet many athletes fail to consume enoughThe importance of protein - how we need more of it post-workout and throughout the day as we ageChanges in hydration and thirst response with ageTraining your gut for better performanceThe challenges of eating disorders and underfueling in older athletesChronic disease risks among older athletes and how nutrition can helpEven if you’re not yet in the Masters age category, you’ll still find this episode packed with useful takeaways to help enhance your performance and nutrition, no matter your age!Please note: We experienced some occasional sound/volume issues during this recording.

Athlete Nutrition Profile - Recreational Ironman Triathlete, Kenny Brighton
Welcome to Episode 42 of the Eat for Endurance Podcast, featuring recreational triathlete, Kenny Brighton. This is my first Recreational Athlete Nutrition Profile since Episode 16 (!!), and I’m excited to bring you more episodes like this one in the months to come.Kenny and I first connected when he got in touch with me back in the Fall of 2019. He was training heavily at the time for an event called the EpicDeca, which is 10 140.6 distance triathlons (i.e. Ironman) on 10 unique courses in the Hawaiian Island in 10 days, and understandably needed some assistance with sports nutrition. I was extremely pregnant with my second daughter, so I referred him to a colleague, but we kept in touch as I wanted to hear how this certainly epic event would unfold for him!Fast forward to early 2021, when Kenny and I finally got a chance to catch up. At this point, he had been training for 10 IM events in 10 days for two years straight, because the 2020 EpicDeca was cancelled and the 2021 August event was delayed, both due to Covid. Unfortunately, Kenny couldn't participate in the rescheduled 2021 event, but for a wonderful reason - he’s becoming a first time Dad this Summer, and wants to focus 100% on his daughter! But after all that training, he had to know - could he complete 10 Ironman events in 10 days? He created his own event on his own timeline near his home in Florida to find out. Have a listen to our pre- and post-event chat to learn all about Kenny, if he was able to complete his longtime goal, and the nutrition, training, and life lessons he learned along the way. Thank you so much Kenny for sharing your experiences with us so openly! It was such a pleasure chatting with you. Wishing you and your wife all the best with the birth of your daughter!Learn more about Kenny:Follow Kenny on InstagramArticle about his event Other Announcements:Please show your support by leaving a rating and/or review on iTunes Have nutrition questions, a guest or topic request, or do YOU want to be on my show?

Athlete Nutrition Profile - Elite Skyrunner, scientist, coach, and author, Hillary Allen
Welcome to Episode 41 of the Eat for Endurance Podcast, featuring elite skyrunner, Hillary Allen. Hillary is such a fascinating, multi-dimensional person and athlete. In addition to establishing herself as one of the best mountain ultra runners in the world (hence her trail nickname of "Hillygoat"), she is a scientist and teacher, with a masters degree in neuroscience, physiology and structural biology, a trail running coach, a gravel cyclist, and now also an author. Her book, Out and Back: A Runner’s Story of Survival Against All Odds, shares her story of survival and recovery after she had a life threatening accident during a 50k Skyrace in Norway. She was nearly halfway through the race when she fell 150 feet off an exposed ridge, breaking two ribs, fracturing her back, rupturing a ligament in her foot, and breaking both wrists. It's a miracle that she was alive, and that she did not injure her head or suffer from other more severe outcomes. She was told she would never run again, but after a lot of rehab and mental fortitude, Hillary made a full recovery and returned to elite level racing. Hillary and I did not rehash the details of her accident , as she has done that plenty of times already. However, it’s an incredibly powerful and amazing story - so if you are not familiar with Hillary or even if you are, I encourage you to read or listen to her book, and/or check out some of her other podcasts interviews that she has done that deep dive into all the details of her accident and recovery. I loved her two episodes (Episode 49 and 168) on The Morning Shakeout with Mario Fraioli, and Science of Ultra had a great one too (she has been doing the podcasting rounds lately for her book, so you can find her all over). Instead, as you’d expect from my Athlete Nutrition Profile Series, we focused on the nutrition side of her story - how it has evolved throughout her life and the role nutrition has played in her extensive and ongoing recovery process - with a few detours along the way (Bugs as food anyone? Yep, we go there!). Hillary, thank you for chatting with me! You are such an inspiration and I hope to see you in Santa Cruz during your book tour. I'd take you for a run in the redwoods, but even with you coming back from an injury, there's no way I'll be able to keep up with you!

Athlete Nutrition Profile - Elite Ultra-Runner and Coach, Lisa Smith-Batchen
Welcome to Episode 40 of the Eat for Endurance Podcast, featuring elite ultra-runner and coach, Lisa Smith-Batchen. I have been trying to get this episode recorded for AGES, and am so excited that our schedules finally aligned for this interview and I am able to share it with you all. Lisa is beyond inspiring - not just because of the incredible things she has accomplished athletically across many decades (a very very long list that includes adventure races, Ironman events, and ultra-marathons), but also because she is a trailblazer for women in endurance sports. She was one of the first to demonstrate that women can compete alongside men and even win endurance events outright. Lisa was the first American to win the Marathon des Sables 150 mile stage-race through the Moroccan desert and has twice won the Badwater Ultramarathon (135 miles through Death Valley). Lisa also is the only person to run from Las Vegas, NV to the summit of Mt. Whitney, covering 306 miles, the first female to complete the “Badwater Quad,” covering 584 miles in about two weeks, and the first and only person to run 50 miles in 50 states in 62 days!At 60 years young, Lisa is a role model for longevity in the sport of running and balancing her passion for running with other priorities in her life. She has two daughters, runs Dream Chasers Outdoor Adventures with her husband, and is passionate about sharing her love of fitness as a teacher and coach. She also is committed to turning her “passion into purpose” by raising money for those in need through her athletic pursuits. As she got older and retired from racing, her runs got longer and she raised an impressive sum of money for charity. Many of her amazing feats of endurance were accomplished in her 50s! We all have so much to learn from Lisa. And believe me, she drops many pearls of wisdom during this interview, so you may want to take notes!Lisa, thank you so much for being so generous with your time and for sharing your athletic and nutrition story. I know I’m not alone when I say, we can’t wait to read your book! ;) Learn More About Lisa:Lisa’s Website: https://dreamchaserevents.comFollow on Instagram and FacebookAnnouncements:Please subscribe to and rate/review the show if you have a minute!If you can afford to donate a few bucks to help support the show financially, please visit my Patreon pageYou can also support me by visiting my Amazon storefront Have nutrition questions, a guest or topic request, or any other feedback?

Relative Energy Deficiency in Sport - A Discussion with Kristin Duyn, MScN
Welcome to Episode 39 of the Eat for Endurance Podcast, during which Kristin Duyn, MScN joins me to tackle the very important topic of Relative Energy Deficiency in Sport (RED-S). Please note that Kristin is a Certified Sports Nutritionist, NOT a Registered Dietitian. I usually only feature fellow dietitians, but she had a really valuable story to share and we had a great discussion, so I hope you enjoy it. What is RED-S? The International Olympic Committee introduced the term in 2014 (think of it as a more inclusive version of the Female Athlete Triad) to include both genders and describe a wider array of negative health and performance outcomes that can result from chronic under-fueling (i.e. low energy availability).Energy availability (EA) is the amount of energy the body can use to perform normal, necessary functions after accounting for the cost of physical activity, which includes both training and other daily activities. Low EA (and eventually, RED-S) results when the body does not have enough fuel to meet its many energy demands. This may happen unintentionally as training volume increases, or intentionally, from trying to control weight, for example. This is a key sports nutrition topic because meeting athlete’s increased energy requirements is essential to optimizing health and sports performance. Many athletes understand this, but still may struggle to fuel appropriately, and that is what I hope to help you with today.Please note that like with Eating Disorders, RED-S doesn’t have a specific “look,” in terms of body weight or composition. Athletes may experience the repercussions of under-fueling while maintaining the same weight, so please look beyond the scale.Here’s what we cover in this episode:Who is at risk for RED-S? What are some warning signs?Kristin’s personal experience with RED-S, chronic injuries, and missed sporting opportunities, How can we make sure we are eating enough, without obsessively counting calories or macros? The tricky topic of weight and performance, esp in the context of minimizing risk of under-fuelingAmenhorrea (loss of period) - why it happens, why it’s not normal or okay, and getting it back Male specific issues related to RED-S and under-fuelingRecovery after bone injuriesThank you so much Kristin for chatting with me all about RED-S and putting up with my long, not always well-thought out ramblings on the topic! Clearly this stuff gets me fired up.Follow Kristin on Instagram:https://www.instagram.com/kdnutritionist/Announcements:Please SUBSCRIBE to and rate/review the show if you're enjoying these episodes!If you can afford to donate a few bucks to help support the show financially, please visit my Patreon pageYou can also support me by visiting my Amazon storefront Have nutrition questions, a guest or topic request, or any other feedback?

Hey guys! I’m excited to bring to you my third (and very overdue) Ask Me Anything episode!

Have a listen to get all the juicy details.Here are some of the questions that I answer in this episode:How often should I recalibrate my sports nutrition plan?I’m training for my first 50k trail run. What are good examples of pre and post run foods?What is the best breakfast before a long run? I’ve been diagnosed with osteopenia as a 30 year old runner, found from abnormal bloodwork. General tips? (FYI - my next podcast episode goes into way more detail on this!)What are easy healthy recipes I can make in the crock pot / ninja pressure cooker for meal prep? (I only own an Instant Pot, but I try to help out as much as I can!)How does an active person determine the amount of protein they actually need?As a vegan, what should I be careful of?What is your perspective on cheat meals / days?

Supplements for Athletes with Sports Dietitian Kelly Jones
Welcome to Episode 35 of the Eat for Endurance Podcast, featuring Sports Dietitian Kelly Jones MS, RD, CSSD, LDN. I invited Kelly on the show to talk all about supplements, and I am confident you will learn SO much from her!This episode is a MUST listen for anyone who is currently taking or thinking about taking supplements, especially as we approach the New Year and all the health-related craziness that always ensues. If you are seeking optimal, sustainable health and performance, it is critical that you pay attention to the research, determine what is actually worthwhile and safe, and separate the FACTS from the myriad opinions and marketing BS that we see on social media and elsewhere.I’ve been wanting to cover this topic for ages. I can’t tell you how many times I’ve gotten new clients on a list of random unnecessary supplements, or been asked some version of the following questions:Should I take a multi-vitamin or other specific vitamins and minerals?Which type of iron supplement should I take?What’s the best protein powder? Can I take it instead of having a meal?I keep seeing collagen and green powders on Instagram - should I try them?Do I need to take fish oil? Probiotics?Should I take BCAAs?Equally, how many times have I asked my own clients, “WHY," such as:Why are you taking digestive enzymes?Why are you drinking two protein shakes a day?Why are you taking Vit B complex (non vegetarians)?Why are you NOT taking Vit D if your Vit D lab result was low?So get out your pen and paper, and get ready to assess which supplements - if any - are appropriate for you.Here are some topics that we cover in detail:Vitamins and Minerals - multi-vitamins and specific nutrientsProtein powders, including collagen Green powders (like Athletic Greens)Fish oil (and vegan alternatives), Probiotics, Digestive Enzymes, MCT OilPerformance supplements, including BCAAs, Creatine, Beta-Alanine, Caffeine, Testosterone Boosters, Beetroot powders and juicesWhat it means for a product to be NSF certifiedThank you so much Kelly for tackling this important topic! And thank you to my listeners for your ongoing support. If we didn't cover a supplement you're interested in, let me know.
