Heart rate, pace, and power are the metrics every endurance athlete tracks, but they're all proxies for what's really happening inside the body. In this episode, Brady sits down with Arnar Larusson, co-founder of Tymewear and the mind behind the VitalPro device. Arnar makes the case for ventilation as a more direct, more stable window into internal workload and fitness.

Carb loading before a marathon is one of the most "accepted" rituals in distance running, but does it actually improve race performance?In this episode of Run Long Run Healthy, Thomas Watson and Brady Holmer break down a brand-new meta-analysis that finally asks the question nobody had rigorously tested: does carbohydrate loading work if you're already fueling properly during the race?If you've ever wondered whether you really need to stuff yourself with pasta the night before your marathon, this episode has the answer.00:00 Introduction: Revisiting the Carb Loading Orthodoxy00:32 What Is Carbohydrate Loading?

Wahoo Fitness spent 15–20 years becoming the data leader in indoor cycling and now they're bringing that same obsession with precision to running. In this episode of Run Long Run Healthy, Thomas Watson and Brady Holmer sit down with Joe Justice and Mac Cassin of Wahoo Fitness to break down the KICKR RUN treadmill, a machine they rebuilt from the ground up instead of just copying what already existed.We get into why cycling data (power, cadence, FTP) doesn't translate cleanly to running, how Wahoo is tackling grade-adjusted pace, vertical oscillation, and ground contact time, and why "durability" and physiological resilience are the next frontier in runner data. Joe and Mac also walk through the three non-negotiable design principles behind KICKR RUN (run feel, speed/acceleration control, and simplified controls), the treadmill's 4-minute-mile top speed, Run-Free adaptive pacing mode, terrain mode, and the Bluetooth headwind fan. Plus, how thermoregulation changes when you take a run indoors.Chapters:0:00 Introduction: Wahoo enters the treadmill game1:04 Why Wahoo built a treadmill from scratch2:03 The cycling-to-running data gap4:00 GPS accuracy & grade-adjusted pace6:20 Individualized metrics vs. population averages7:55 Physiological durability & resilience scoring10:24 Sponsored by Kila custom insoles12:37 Turning treadmill data into actionable feedback14:43 Inside KICKR RUN's 6–7 year development story16:39 The 3 non-negotiable design principles19:35 Why treadmill speed limits held runners back21:24 Run-Free mode, terrain mode & the headwind fan26:16 The case for precision in indoor training27:33 Reframing the treadmill as a tool, not a fallback29:58 Thermoregulation, sweat & heat adaptation indoors33:57 Reducing mental load to stay motivated38:13 The next 10 years: AI, wearables & training data44:07 Explaining Wahoo's 3DP/4DP performance models50:09 Will AI ever replace a running coach?55:42 Integrating cycling into your run training58:53 Where to demo the Wahoo KICKR RUNCustom insoles made with supershoe foam: visit kilarun.com and use code “RLRH” to get $50 off your first order.Check out the KICKR RUN Treadmill:https://www.wahoofitness.com/devices/running/treadmills/kickr-run-buy
