Running Training Decoded

Stuck on a plateau, constantly injured, or exhausted from a training log full of runs that are all the same uncomfortable "pretty good" pace?

You're not undertrained. You're very likely training in the wrong zone most of the time.

Running Training Decoded takes the training-intensity split long documented in elite endurance athletes and turns it into a plan any runner can follow: roughly 80% of your weekly running kept genuinely easy, and 20% reserved for precise, purposeful hard effort-with almost nothing wasted in the tiring, moderate "Gray Zone" in between that burns runners out without making them faster.

What you'll do with this book

• Find your real training zones without a lab. Three field-test methods build your own Personal Pace Chart in under an hour-no expensive testing required.

• Pick the structure that fits your week. A short self-assessment matches you to a 5-6 day schedule, a threshold-focused approach, or the book's 3+2 System (three running days plus two cross-training days) for weeks that can't fit more.

• Follow a complete, distance-specific plan. Full 12-18 week training plans for the 5K, 10K, half marathon, and marathon.

• Train your hard 20% correctly. Dedicated chapters on VO2max intervals, hill sprints, and threshold training, including exactly when advanced tools like double-threshold sessions are (and aren't) appropriate.

• Stay off the injury list. Runner-specific strength and mobility work targeting the shin splints, plantar fasciitis, and IT band issues that sideline the "harder is better" crowd.

• Recover like it's part of the plan. A full chapter on sleep, fueling, and reading your own recovery signals, plus a weekly check-in you'll actually use.

• Race on purpose. Pacing strategy, a race-week countdown checklist, and mental tools for executing under pressure instead of hoping for the best.

Who this book is for

New runners who want to start on solid footing instead of guessing. Intermediate and advanced runners stuck at the same finish time for multiple training cycles. Busy runners who can't manage five or six runs a week and need a plan built for three. Masters runners over 40 who need their training adjusted, not abandoned. And anyone tired of feeling constantly tired without getting faster.

What's inside

24 chapters organized into a clear progression: the physiology and philosophy of polarized training, a full zone system with field tests, distance-specific plans for every major race, high-intensity and threshold work, strength and mobility for runners, recovery science, race-day execution and mental training, weather and travel adjustments, masters-specific guidance, and a troubleshooting chapter for when training goes sideways. Includes a glossary and three reference appendices, plus dozens of tables, charts, and worksheets built to be filled in, not just read.

Every method here comes with the reasoning behind it: where the science is settled, this book says so plainly; where it's still debated, that's reflected honestly rather than oversold.

Run stronger. Recover faster. Train with a plan built on how your body actually adapts.
