    Carb Loading Before a Marathon: Science or Old-School Advice?

    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?

    Bringing the Cycling Data Revolution to Running: Wahoo on Data, Speed & the Future of Indoor Running

    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.
