REDs & Running a Marathon: "How much damage will I do if I run anyway?"
Lane 9 Podcast
" Consider why you want to do this. What are the motivating factors for completing the marathon right this second? What are your long-term health and movement goals, and does this get you closer to them or further away?" Lane 9 co-founder, and dietitian, Heather Caplan RDN takes on two more listener questions in this episode. 1) How do clinicians navigate what may be REDs, with an athlete who has an IUD and doesn't get periods? 2) If I'm undertrained and experiencing symptoms of REDs (haven't had a period in about a year), but I want to run marathon, what should I do? As always,...

Q&A: Overall health, with irregular or absent periods & What if I recover from REDs...and get slower?

Nutrition Support for College Athletes with former D1 Athlete Lauren Segal RDN
Lane 9 Podcast
"Athletes aren't immune to that messaging of like, 'carbs are bad, you shouldn't have carbs, and they're the worst thing ever.' But we know that carbs are our body's preferred source of fuel, especially when you're doing these intense bouts of exercise like most athletes are doing," shares sports dietitian Lauren (or Lo) Segal.

Periods & Nutrition Q&A: How to know if "a lot" is "enough" for energy availability
Lane 9 Podcast
"I've found that athletes vastly underestimate their [energy] needs," shares Heather Caplan RDN, co-founder of Lane 9, in this Q&A-style episode. Listen for this one if you're wondering... How often is it okay to have sweet things/desserts? Is it possible to have REDs without weight loss/changes? Why am I not getting my period back, even though I'm eating a lot more? This one tackles flexibility with food, decades of carb-fearing and how it probably still impacts what most people eat on a daily basis...even in sports, weight stigma in athletics and the variety of REDs symptoms, and...

Leah Avery DPT with Coaching Advice to Avoid Overtraining
Lane 9 Podcast
"Once I started to really add fueling into the long runs...I realized how much that was helping the next run," shares Dr. Leah Avery DPT. Leah Avery DPT was a D1 collegiate swimmer, who qualified for NCAA championships and the Olympic Trials (2008). On paper, her athletic story reads as inspiring and exciting for a young athlete. In reality, it was a pressure-filled struggle to keep up with expectations, training, and results. She was ready to be done.

Jenny Grimshaw on how Understanding ARFID, Food Intolerances, and Anxiety Changed her Running

Jenny Grimshaw, VP of marketing at EQUIP*, and now a 2:36 marathoner, joins us on the Lane 9 podcast. Jenny is also a mom of 2, and navigating prophylactic surgeries to reduce her risk of breast and ovarian cancers (with the BRCA-1 gene). Her postpartum running experiences have been full of PRs, as she has figured out her own fueling needs, how to balance her identity as a runner with all the other things she does, and has worked with a coach to better balance her training volume and find her confidence as a runner.
Jenny shares:
- her early experiences with food intolerances and GI distress that were assumed by physicians to be anorexia, but would later be more correctly classified as ARFID
- the anxiety and panic attacks that she dealt with as a young runner, and injuries that plagued her through college, related to fueling, mental health, and wanting to explore life outside of running
- why she got into longer distances after her collegiate T&F years
- the gastroenterologist appointment that changed everything for her
- how she brought her marathon PR from a 3:13 to a 2:36 (not to say "you can, too!" but to give just one example of how fueling and mental health impact our experiences in sport)
- why she was drawn to EQUIP, and her role there
*EQUIP is a virtual eating disorder treatment company that offers care in all 50 states. They're also part of the Lane 9 Directory.
