Power Meters, Double Run Days & Swim Speed: Your IRONMAN Questions Answered | Ep 578
This week Coach Rob digs into listener emails, answering questions from athletes building toward their first Ironman. He covers whether a single-sided power meter is enough...Whether splitting your long run into two sessions is a good idea...How offshore workers with limited pool access can still make progress in the swim. Plus, Rob shares a real example of two athletes dropping 20 seconds per 100m in a single session through one targeted drill and explains why fitness alone won't make you faster in the water. Along the way, he reflects on why the advice you take matters just as much as the training you do, and why longevity in the sport should always come before chasing marginal gains. If you're a first-timer figuring it all out, this one's for you.* * * * * * *SPONSORS* * * * * * * *Thinking about your first Ironman or 70.3 in 2026?
