Episode 3 — How Josh Kerr Broke the Mile World Record on 70 Miles a Week

3:42.66. The first human under 3:43. A 27-year-old record, gone.

And Josh Kerr did it on 65 to 70 miles a week, six days out of seven, with two workouts, no double days, and no lactate meter anywhere in sight. Coach Jason Saltmarsh breaks down the training system behind the mile world record, and what it actually teaches high school coaches.

You'll hear why consistency, not volume, is the real training plan, why Danny Mackey caps Kerr's week for repeatability instead of show, why a 1500m runner should train like a 5K runner (and the physiology that proves it), how Mackey extended a proven benchmark workout instead of replacing it, and why 12 hours of daily rest matters more than any workout on the schedule.

The number is the wrong question. Here's the right one.

Coach Jason Saltmarsh answers the single most-asked question in high school distance coaching, and explains why volume rarely breaks freshmen, intensity does. You'll learn why running age matters more than the birth certificate, the three freshman archetypes that all need different plans, why strides are mandatory and not optional, and how to build mileage with step cycles instead of the outdated 10% rule.

If you've ever capped a freshman out of fear and wondered why they never developed, this one's for you.

The hardware isn't the point. The process is.

In the first episode of Salty Talks, Coach Jason Saltmarsh opens up about the moment at Derryfield Park that changed how he coaches, and why 31 state championships came from everything around the workout, not the workout itself.

You'll hear why the perfect Tuesday session is maybe 20% of your season, what Joe Vigil's Adams State dynasty actually teaches high school coaches, and the three things that separate programs that win once from programs that win for decades: periodization you commit to, individual attention inside a team structure, and sustainable excellence over a single good year.
