Lydia O’Donnell is a New Zealand 10K national champion, a 20th-place finisher at the New York City Marathon and the founder of FEMMI, a running app built specifically for women. In this episode, Lydia shares how years of underfueling, overtraining and pressure to make her body smaller brought her running career close to breaking point. After losing her period and eventually landing in hospital, she began learning about female physiology, changing her relationship with food and adapting her training around what her body genuinely needed. The result was a remarkable late-20s breakthrough in which she improved her personal bests across every distance from 5K to the marathon. We explore the warning signs athletes commonly ignore, why weight loss isn’t the answer to better performance and how women can adjust training across the menstrual cycle. Lydia also explains how FEMMI personalises its running programs, why every female athlete should track her cycle, how she approaches hydration and heavy strength training, and where research into female physiology still needs to improve.

Episode breakdown: 00:00 — How has HYROX training changed from 2020 to 2026, and what were people getting wrong early on? 01:50 — Why did elite athletes start dialing in an “ideal race weight,” and how do you find the sweet spot between muscle and run pace? 03:44 — Should most athletes try to gain/maintain weight for HYROX, and how do you test where your tipping point is? 04:40 — Why might HYROX be more sustainable long-term than Ironman/ultras, and what does that change about training priorities? 05:39 — Is HYROX “mostly endurance,” and why do long hill efforts often beat gym max-strength for real station performance? 07:26 — Do newcomers need an aerobic “base sport” first, or is the right plan entirely dependent on their current background? 10:36 — What questions do you ask a new client to personalize training, and why do “circumstances” matter as much as fitness? 13:58 — What is a “test week,” and how do you use it to set paces, strength targets, and training intent? 15:57 — How do you keep performance high while running very little due to injuries, and where do you “get the stimulus” instead? 18:16 — Will elite training keep shifting toward high-volume, low-impact work (ergs/bikes), and why does it beat more running? 21:06 — How should strength training look for HYROX if max strength isn’t the main limiter? 22:42 — What’s a practical playbook to improve sleds, and why do hills + varied sled loading matter more than “race weight only”? 25:17 — Why do wall balls break people (mobility + technique), and how should you train them under fatigue instead of fresh? 28:15 — How do you define “efficiency” on stations, and why might being slightly slower but fresher be the winning tactic? 30:27 — What are the best ways to teach efficiency (video, timing, stroke rate, settings), and why is it all trial-and-error? 35:44 — What keeps you motivated to keep competing for years, and how does community (and family) shape that? 41:35 — How do you enjoy the sport more—especially if you’re always chasing PBs or comparing yourself to others? 48:34 — What advice would you give to someone who wants to build a coaching career in HYROX without becoming “generic”? 53:11 — What training trends are you watching in early 2026 (volume pullbacks, coach changes), and will more elite runners enter HYROX?

Dr. Richard MacKenzie is an associate professor specializing in human metabolism and a clinician working at the intersection of exercise physiology, metabolic health, and stress. He is the author of Stress Tested: How The New Science of Stress Hormones Can Transform Your Health . In this episode, Richard unpacks what stress actually is from a physiological perspective, how acute and chronic stress differ, and why chronic stress can quietly undermine insulin sensitivity, recovery, sleep, and training adaptations. We also explore how stress shows up in metrics like heart rate variability, glucose variability, and fuel metabolism, why mindset and perception dramatically alter stress responses, and how exercise, nutrition, caffeine, sleep, and even cold exposure can either buffer or amplify stress. Episode breakdown: 00:00 – Who is Dr. Richard MacKenzie? 00:16 – Why write Stress Tested now? 02:23 – What is stress? 04:28 – When does stress turn from helpful to harmful? 04:52 – How does chronic stress show up day to day? 06:15 – Can stress actually be measured? 07:41 – What does a personal “stress dashboard” look like? 09:59 – How changeable is stress with mindset? 13:59 – Does exercise reduce stress—or add to it? 15:29 – Is stress one of our biggest health threats? 19:56 – What hidden stressors are we missing? 26:06 – Can diet increase—or reduce—stress? 36:04 – What has stress research changed for Richard? 41:05 – What’s next: protein, metabolism, and future research?

Gommaar D’Hulst is an exercise physiologist at ETH Zurich and the mind behind the WOD Science YouTube channel, with a background rooted in CrossFit and a growing focus on HYROX and hybrid endurance sports. Through his research and applied lab work, Gommaar bridges elite performance, physiology, and real-world training decisions for functional fitness athletes. In this episode, Gommaar breaks down the key physiological differences between CrossFit and HYROX, why HYROX is best understood as an endurance-dominant sport, and how muscle fiber types, VO2 max, lactate threshold, and anaerobic power shape performance. He shares insights from lab testing with elite athletes—including novel functional ramp tests using burpees and thrusters—explains why fatigue dramatically alters running economy in HYROX, and explores how tools from endurance science (like threshold training, Zone 2 work, and power metrics) can be adapted to functional movements. We also dive into interference effects, fueling strategies, and where sports science is headed as HYROX continues to professionalize. Episode breakdown: 00:00 — Intro: Gommaar (ETH Zurich) + WOD Science + CrossFit → HYROX 00:24 — CrossFit vs HYROX demands: longer duration, lower intensity, aerobic bias 01:40 — Can you excel at both? Specialization, rising level, and the Tia example 03:13 — Is HYROX endurance or strength? Why it’s primarily endurance (and sled/turf impact) 04:48 — Muscle fibers 101: slow vs fast twitch and what they’re built for 07:50 — Why strong powerlifters can struggle: strength vs strength-endurance 11:01 — HYROX strength training: when (and if) low-rep work fits in the season 12:17 — VO2 max + lactate threshold: what they are and why they matter 15:56 — Elite CrossFit VO2 findings: lower-than-expected on the bike + specificity issue 18:27 — Functional ramp test: burpees + thrusters protocol + what lactate curves show 21:55 — Run → lunges/deadlifts → run: fatigue increases VO2 cost (running economy drop) 26:02 — What predicts HYROX performance beyond VO2: fatigue-resistance across stations 28:22 — Heart rate: good for running, limited for stations + why VO2 can drop in strength work 34:15 — Interference effect: separating strength and endurance (same-day vs split) outcomes 46:53 — Nutrition rapid-fire: carbs (timing + high intakes) and bicarb/creatine practicality This is a public episode.
