After our interview with Advanced Marathoning author Pete Pfitzinger, I wanted to dig deeper into some of the key lessons he shared about smart, effective marathon training — from threshold workouts to the value of interval sessions and when (or if) to add doubles.

🎁 Run Farther. Recover Faster. Give the Gift of Endurance.
As the air turns crisp and the holidays approach, every runner knows—the hardest part isn’t just getting out the door, it’s finding the fuel that carries you through the miles and the season. Coffee fades. Pre-workouts crash. Energy drinks spike and burn out.
But what if your energy didn’t just last through the run—what if it powered you through your entire day?
That’s where Pique comes in. A luxury wellness brand powered by rare plants and cutting-edge ingredients, Pique is the perfect gift for the runner (or wellness lover) in your life. Their science-backed botanicals, minerals, and adaptogens support steady energy, faster recovery, and stronger immunity—just what every athlete needs to thrive through winter.
Meet Nandaka—Pique’s secret weapon for endurance that lasts. Built to fuel focus, stamina, and recovery, it’s made for runners who don’t quit when the weather turns cold.
The Marathon Handbook team put Nandaka to the test—and the results spoke for themselves. Instead of the spike-and-crash of coffee or pre-workouts, we felt steady energy that carried us through long runs and busy days alike. Recovery came faster, focus felt sharper, and that dreaded afternoon slump? Gone.
✨ Why Runners Love Nandaka
Steady, Long-Lasting Energy – Slow-release caffeine from probiotic teas keeps you powered without jitters or crashes.
Peak Performance & Recovery – Ceremonial-grade cacao, prebiotic fiber, and fruiting body mushrooms boost focus, gut health, and stress resilience.
Unmatched Purity – Only the cleanest, highest-quality ingredients—crafted for athletes who demand the best.
Whether you’re gifting your favorite marathoner or treating yourself to the ultimate training upgrade, Nandaka is the perfect way to fuel every finish line this season.
In our recent chat with marathon legend and coach Pete Pfitzinger, he emphasized one thing all serious marathoners should do: get in at least one threshold workout per week.
Threshold runs train your body to hold faster paces longer and recover quicker. We’ll break down exactly how to do them (without overdoing it!) and share a few time-based workouts you can plug right into your training plan.
Pfitzinger told us he’s removed doubles from most of his current training plans—but that they can still be an effective tool if you’re trying to increase mileage safely and have the time.
We break down when doubles make sense, who should avoid them, and how to use them without overtraining.
Interval sessions aren’t just for elites — they’re one of the most effective ways to build speed and endurance. In Advanced Marathoning, Pete Pfitzinger includes them as a cornerstone of his plans, and we do the same in our Marathon Handbook training programs.
I’ll break down how to structure your intervals, balance recovery, and add these workouts into your own plan for maximum results.
Dreaming of running one, or all, of the Abbott World Marathon Majors?
Tokyo, Boston, London, Sydney, Berlin, Chicago, and New York each have their own unique—and sometimes confusing—entry systems.
In this guide, we break down every way to qualify or gain entry, from time standards to lottery odds and charity spots, so that you can turn that dream bib into reality.
