Running Plan Review Greg McMillan 5K: Intermediate (Speedster)

Does it build you up smartly?

Partly. The plan has a sound shape, but the schedule doesn't show it to you.

Every hard day is written as a recipe: how many repeats, how far, how much jogging between them. What the session is for, and how it fits the weeks around it, lives in the book's chapters. There are no named phases either. Reading week 6, nothing tells you that the plan has just moved from one hard day a week to two, or that the next few weeks are the heart of it.

The lighter weeks have a similar catch. Every fourth week eases off, which follows McMillan's own advice, and lighter weeks are when recent training settles in as fitness. But week 8 trims the minutes while Thursday's fartlek and Sunday's time trial still ask you to run hard twice. Your legs get a break from volume that week, but not from effort.

What the plan gets right is the order. Training in stages beats holding one steady load, and McMillan's stages make sense for a fast runner. Steady threshold work fills most of the build, goal-pace work and time trials grow denser near the end, and race week is easy.

It also starts where a Speedster is strongest. The first hard session of the plan, in week 1, is 10 to 12 repeats of 400 meters at goal pace, the most repeats of any session on the schedule. If you come in from weeks of easy running, that's a big first Thursday. Week 11 returns to the same session with fewer repeats, so you can feel how much easier goal pace has become.

Does it protect you from injury?

Injuries tend to show up after the weeks that change most. Many that look like slow overuse actually start suddenly, often set off by something in the week before. So the question for any plan is where its big changes land.

Here, they cluster in 2 weeks, and both are the plan's weak point. Week 6 is the biggest week so far, and it's also the week Sunday turns from an easy long run into a run that finishes fast. Adding a second hard day is sound progression, but here it arrives together with more running. Week 9 follows the lightest week of the build and only returns to the level of weeks 6 and 7, so on paper it's a homecoming. But it gets there in one step, about twice the running of week 8, with threshold repeats on Thursday and a fast finish on Sunday. Sharp jumps in weekly running raise injury risk, and a hard week on legs that just eased off is still a jump.

Strength is left to you as well. The book includes a sample strength routine and points to a full program online, but the calendar has no day for it. That's a real gap. Strength training substantially lowers the risk of injury in sport, and a fast runner doing hills, time trials and goal-pace repeats has more reason than most to do it.

Warm-ups have the same problem in smaller form. The book teaches you to warm up before hard work, but the schedule doesn't print one on the day.

Three things protect you well. Thursday and Sunday always have at least 2 days between them. Outside those 2 weeks, the running rises in modest steps. And the book teaches you to read your body. A low-grade ache that hangs around appears to raise the odds of a full injury, and McMillan gives you whole chapters on spotting those warning signs, backing off, and recovering well.

What happens when you miss a day?

Over 12 weeks, something will get in the way of a Thursday. The test is how much of the plan you can save when it does.

Here it helps less than it could. The book has no rule for a lost week, so whether you pick up where you left off or step back is your decision. And while the book implies that long runs and hard days matter most, it never ranks the sessions, so in a crowded week you're left to choose between Thursday's repeats and Sunday's run on your own.

But the plan has real give in it. Wednesday and Friday are optional every week, so a lost day often costs you nothing at all. From week 5, easy runs come as ranges in minutes, and the book tells you to take the low end when you're tired. On a bad day, it lets you move a hard workout or skip it.

The pacing bends with you too. McMillan teaches effort over pace, using 4 effort zones, and asks you to judge each day by how you actually feel before you decide how hard to go.

Will it get you ready for race day?

Yes. Race readiness is this plan's strongest side.

A 5K asks you to run near the top of your aerobic range from the gun to the finish, which is why practicing goal pace earns its place. Race-pace work pays off most when the race sits near one of your body's limits. This plan starts it in week 1 and brings it back right to the end, with 400-meter repeats at goal pace on the last Sunday before race week.

Underneath that sits the threshold work, the 1000-meter repeats at a hard, steady effort that show up every few weeks. Your threshold decides how long you can hold a strong pace, and it rises when you train at it. For a Speedster, it's what keeps the third mile from falling apart.

The time trials let you practice the race itself. In week 8, you run 1 to 1.5 miles at goal pace, or race a short tune-up. In week 10, it's 1.5 to 2 miles. Both teach you how goal pace feels in the stretch where every part of you wants to slow down.

Sundays carry the endurance. The long run reaches 60 to 75 minutes early, then turns into progression runs that finish fast. Race week then cuts your running about in half, and easing off before a race improves how you perform on the day.

Are the workouts varied enough?

The fastest runners don't train at one speed. Mixing mostly easy running with clearly hard sessions builds more fitness than steady, medium effort.

This plan is full of that mix. No Thursday repeats the one before it. Across 12 weeks you'll run goal-pace repeats of 2 lengths, repeats of 1000 meters, a steady run, hill repeats, fartlek with 1-minute surges, progression runs and time trials. The threshold work stretches your speed out, the goal-pace work teaches you to hold it, and the hills and surges bring short bursts of power.

The easy running holds it all up. About 83 percent of the running is easy, and easy miles form the base that lets your body absorb the hard work. With the hard days kept apart, you come to each one fresh enough to run it well.
