Running Plan Review Greg McMillan 10K: Novice-Intermediate

Does it build you up smartly?

The workouts come in a sound order, but the plan asks for 7 weeks of growing work before it lets up, and the schedule says what to run without saying why.

Training works best in stages: plans that shift their focus block by block race better than plans that hold one load all the way through. They also ease off every few weeks. Those lighter weeks matter more than they feel like they do: they're where the fatigue clears and the work of the weeks before becomes fitness.

Here, the first lighter week is week 8. The book itself allows a down week every fourth week, but the schedule doesn't print one until the steady runs, threshold repeats, tempo running and the first goal-effort session have all arrived. Even week 8 holds a session of 400s and a 75-minute long run. After that the plan alternates: a big week 9, a lighter week 10, a big week 11, then race week. A runner who wants a break at week 4 has the book's blessing, but working out what to cut is left to them.

The schedule is also spare. Each workout is printed as an instruction, such as a steady run of 15 to 25 minutes a notch below comfortably hard, with nothing on what that run is building. The book does explain every kind of run in its own chapters, so the answer exists. But it lives in a different part of the book from the day you're about to run.

What the plan gets right is the order. Easy running and strides come first, then sustained hard running, then goal effort, then the race. Each block leans on the one before it, so the 6 goal-effort miles in week 9 come after several weeks of steady, tempo and threshold work that got your legs ready for them.

Does it protect you from injury?

Injuries tend to follow change. Sharp jumps in weekly running raise the risk, and so does new, harder work that arrives before the legs are ready. Blood and metabolism adapt within weeks, while tendons and bone take months to catch up, so a runner can feel ready for more before the body underneath is.

This plan stacks those changes. Week 7 brings the first goal-effort session in a week about a quarter bigger than week 6, after 6 weeks without a break. Week 9 is the biggest week of the plan, with 6 goal-effort miles on Thursday and a fast finish on Sunday. Neither jump is extreme on its own. But a runner coming back from a sore Achilles or a stress injury will feel these weeks first, and no lighter week comes before week 7 to freshen the legs for it.

Strength is left to you. The book shows a sample routine and sends you online for the rest, but no strength session appears on the schedule, so when it happens, or whether, is your call. That's a real gap, because strength work lowers injury risk in sport more than stretching does. The optional days are a natural place for it, but the plan never says so.

The plan does protect you in other ways. Across 14 hard sessions, a hard day is never followed by another one. The 3 open days help too: on a week when your legs feel heavy, rest is already one of the printed options, not something you have to talk yourself into. And the book gives a full chapter to warning signs and how to respond to them. Week 9 is where that chapter earns its place. An ache that's still there on Friday after Thursday's goal-effort miles is a reason to keep Sunday's finish easy, because low-grade aches like that appear to raise the odds of an injury that interrupts training.

What happens when you miss a day?

Partly. Day to day it bends easily, but when a whole week goes wrong, the plan has no answer ready.

The gaps come with bigger disruptions. The book implies that the long run and the main workout matter most, but it never says what to drop first. Say week 9's Thursday falls through. Friday and Saturday are both open, so you could run the 6 goal-effort miles on Saturday and face Sunday's progression run the next morning, or let them go and keep the rest of the week as written. Nothing on the page helps you choose, and nothing covers a week lost entirely.

The everyday bending is where the plan shines. In most weeks, 3 of the 7 days are already a choice between a run, cross-training or rest, and the fixed runs come as ranges. The book lets you take the low end of a range when you're tired, and skip or move a key workout on a bad day. Every run is described as an effort, in a system of 4 training zones, the kind of framework the research favors, adapted from David Martin, one of McMillan's mentors. On any given day, the book asks you to train the runner who showed up, not the one on paper.

Will it get you ready for race day?

Racing a 10K, rather than surviving one, means holding a hard effort from the first mile to the last without fading in the middle. That staying power is trained by running near it, because threshold gains are specific to the pace you train them at.

This plan does that from week 2 onward. Steady runs, 800-meter repeats and tempo runs come first. Then the goal-effort work grows: 4 miles in week 7, split into a 2-mile piece and 2 single miles; 6 miles in week 9; and in week 11, 6 miles again as 3 longer pieces of 2 miles each. By race week, you've run nearly the full distance at goal effort in pieces, and you know what the middle miles feel like.

Week 10 brings a dress rehearsal. The Sunday session is a 5K run at your 10K goal effort: half the race, at the effort you plan to hold. The book offers a 5K race in its place, and uses either result to check whether your goal is right. That's useful information 2 weeks out, while there's still time to adjust.

The long run is well matched to the race. It grows from 45 to 60 minutes in week 1 to 75 minutes in week 8, and the progression run in week 9 reaches 65 to 85 minutes. Race week then drops sharply, with one short session of 1-minute surges midweek to keep your legs sharp. A lighter final stretch like this reliably helps runners race faster.

Are the workouts varied enough?

Yes. Thursday brings a different workout almost every week, and the rest of the running stays easy.

Runners get fitter when they keep easy days truly easy and hard days clearly hard, and clearly hard sessions mixed into easy running build endurance better than long stretches of steady, medium-hard running. Changing the kind of hard session from week to week keeps each one fresh.

This plan does both. About 82 percent of the running is easy. The Thursdays move through strides, steady runs, 800-meter repeats, tempo runs, goal-effort miles and 400s, and no 2 Thursdays in a row are the same. Three of the Sunday long runs end with a fast stretch, one Sunday is the time trial, and race week brings a short fartlek.

For a runner whose first 10K came from running most days at the same medium effort, this is the plan's biggest lesson. The easy days will feel almost too easy, and they should. That's what lets Thursday be properly hard, and lets you show up for it again the next week.
