— 5/5 Stars
The value of this book and audiobook is honestly hard to put into words. What Jack created here is something a “normal” working person simply couldn’t figure out alone—at least not without years of trial and error. The structure, clarity, and practical relevance are outstanding.
I devoured the first part—the podcast chapters—on several long drives. I felt bad at times because I couldn’t take notes while driving, but I was so eager to absorb everything that I didn’t want to wait until I might find the perfect quiet moment. I replayed several chapters multiple times, and even during a long-haul flight I went back through key sections, took notes, and turned them into a short guideline for myself.
I learned a tremendous amount.
The range of topics is impressive. Every major area that matters for cyclists is covered.
For me personally, the basics were the most valuable. I consider myself to be riding at a reasonably high level compared to the general population, and with limited time—family, a demanding job, and life in general—I need to focus on what truly moves the needle. The basics are exactly that, and as explained in the book, they’re often overlooked.
I’ve never been the type for heavy supplementation. Apart from vitamin D, the occasional salt tablets and BCAAs during sessions, I’ve always preferred to keep my body as “clean” as possible. So I’ll be honest: the supplement chapters were less relevant for me, and I skipped a few of them. But that’s simply personal preference, not a criticism.
What truly shifted my perspective was the combination of fueling during sessions and maintaining a shorter eating window. I used to underfuel on the bike—especially toward the end of my rides—because I wanted to “save calories” for later. It backfired every time. Although I always reached my race-season weight again, the off-season was a struggle. Over the past years I added roughly 6 kg each winter, which I could drop again, but only with a level of discipline that constantly drained me.
The approach in this book changed that. The tighter eating window works incredibly well for me—something I never thought possible. Skipping meals throughout the entire day never suited me, but skipping breakfast and waiting until midday works beautifully. I even laughed at myself when Jack described inhaling food like a horse—I saw myself 100% in that description. And the shift from “refuel later” to “fuel during” has been a game changer. My sessions burn around 1000 calories per hour at higher intensities, and trying to compensate after the ride threw me completely off balance. I even went through a phase after my last race block this September where I craved Nutella so badly that I ate multiple jars in a short period of time. Now, with proper fueling during rides and a structured eating window, the system finally feels stable. I feel in control again.
