Your 5K runners are slow because they can't sprint.

Last meet of the season, we needed a body for the 4x400 and someone said the fatal sentence: "He's in shape, put him in the relay." My best miler split 64. A sophomore sprinter who has never voluntarily run more than 600 meters split 52 and made it look easy. Danny was fitter than everyone in that race. He was also, mechanically, slower than a kid who couldn't finish a two-mile.

That relay is this whole episode.

Speed reserve is the gap between how fast an athlete can possibly run and how fast they actually race. Two kids both running 75-second laps for a 5:00 mile: one is at 73% of his max, the other is at 90%. Same pace, completely different race. One is cruising with a gear left. The other has been redlining since the gun.

In this one:

• The two-athlete math that reorganized how I think about race pace
• Why Paavolainen's runners got faster at 5K with zero change in VO2 max
• The three rules that make sprint work actually work (and why cutting the rest ruins it)
• Wickets, flying 30s, and short hill sprints, with the freshman and varsity versions of each
• The high/low week that fits speed in without costing you a single aerobic mile
• The four mistakes that make coaches conclude "speed work doesn't do anything"
• Whether sprinting is actually an injury risk, or the vaccination against one

Plus what happened to Danny the following season, and the one sentence he said after his mile that I've never forgotten.

If you listened to Episode 6 and think this contradicts it, stick around for the intro. It doesn't. It's the other half of the sentence.

Coach Jason Saltmarsh takes on the job almost nobody plans for: getting handed a middle school team. Most coaches make one of two mistakes with it. They water down the varsity plan, or they treat it as supervised recess. Both cost you the same thing, which is the freshman class that walks in two years later.

This episode covers what the job actually is, why minutes beat miles at this age, and how to deliver real training to athletes who will race anything you put in front of them.

• Why the number on the schedule should be minutes, not miles

• How to run a hard workout that a twelve-year-old cannot turn into a time trial

• The seventeen minutes of every practice that most coaches skip

• What USATF actually says about race distance, and the number to quote to a parent

• One loop, one clock, six doses: coaching grades five through twelve at once

A freshman on a July tempo run tells her coach she's fine, she just needs to get used to the heat. She wasn't fine, and she'd just turned a physics problem into a story about being out of shape. With a dangerous heat dome sitting over much of the country this week, Coach Saltmarsh breaks down how to train through summer heat without wrecking the fall season: why sweat only cools you when it evaporates, why dew point beats temperature and humidity as the number to watch, exactly how much to slow down, the hydration math nobody actually runs, and the safety line no workout is worth crossing. Two free tools in the show notes: the heat pace calculator and the rehydration calculator.

This episode is training guidance, not medical advice. Suspected exertional heat stroke is a medical emergency. Cool the athlete aggressively and call 911.

A girl runs 13:21 at Van Cortlandt as a sophomore, and her coach's first thought is how to make sure she's still running in four years. That instinct is the whole story. In this first case-study episode, Coach Saltmarsh walks the full arc of Katelyn Tuohy's career, from seventh-grade national records to a pro contract, and pulls out the specific, stealable decisions two coaches made along the way: keeping your best runner in the group, taking the stopwatch away for a month every summer, training the finishing kick on purpose, and coaching the whole athlete instead of the training log. Protect first, develop second. Here's how to actually do it in your program.

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.
