Heart Rate vs Power for IRONMAN Training + Altitude Training Explained | Ep 601

<p>In this episode:</p><ul><li><strong>Racing without a power meter</strong>: why Rob thinks a power meter is a &quot;worry removal tool&quot; rather than a cost, and how to reframe the spend over your training block. If you&#39;re going with heart rate, he covers the five variables that distort it, the time-lag that trips you up, how to set functional threshold heart rate from a 20-minute test, and the thirds-based pacing method that accounts for cardiac drift.</li><li><strong>Training at altitude for a sea-level race</strong>: why you need two sets of zones, not one. How to find your delta between altitude and sea level, and why heart rate gives you a bridge between the two while pace never will.</li><li><strong>Shoulder pain in the aero position</strong>: normal adaptation or warning sign? Why &quot;I&#39;ve had a bike fit&quot; doesn&#39;t rule out a problem, why pain in the water as well changes the picture, and why regular hands-on physio work beats pushing through it.</li><li><strong>Success story</strong>: Listener Max takes on IRONMAN Switzerland in 30°C heat with 2,200m of climbing and comes home in just over 12 hours!</li></ul><p><br></p><p>Got a question for the show, or a first 70.3 or IRONMAN story to share?
