Running Plan Review Greg McMillan Marathon: Advanced (Endurance Monster)

Does it build you up smartly?

A marathon block should get more specific as the race nears, and this one does. Hills and progression runs open the plan, goal-pace running comes in during weeks 4 to 6, and the biggest long runs and longest goal-pace runs fill weeks 7 to 9. Then the work comes down for 3 weeks before the race. Plans that shift their emphasis from block to block like this race better than plans that hold one load all the way through. The running also eases off every fourth week, as the book recommends, and a lighter week every few weeks lets fatigue clear so the training sticks.

But the schedule never tells you any of that. The blocks have no names, and each workout is printed as instructions only: a time or distance, an effort, a number of repeats. Why Tuesday's progression run follows Sunday's long run, or what week 1's hill repeats are building toward, is explained in the book's chapters, not on the page you train from. A runner who knows McMillan's method can fill that in. One who doesn't will follow the weeks without seeing how they connect, and will have a harder time judging which parts of a session matter when the day goes wrong.

Does it protect you from injury?

Mostly, yes, with three things to handle yourself.

The first is strength. McMillan includes a sample routine in the book and points you to a full program online, but none of it is on the calendar. Finding room for it around 2 hard days and a long run is your job, and it's worth doing, because strength training cuts sport-injury risk more than stretching or balance work does.

The second is two big weekly rises. Week 5 runs about a quarter more than week 4, and it brings the plan's first set of 800-meter repeats along with a long run of up to 24 miles. Week 7 climbs about a fifth over week 6 and brings the first long run of 22 to 26 miles. Your heart and lungs keep up with rises like these sooner than your legs do, because tendon and bone adapt on a slower clock. In both weeks, take the low end of the ranges if anything feels off.

The third is the warm-up. The book asks for one before hard sessions, but the schedule never prints it. Before a tempo run or a set of 800s, add an easy start of your own.

Otherwise, the plan looks after you. No 2 hard days ever fall back to back. If you reached this kind of mileage gradually, over months, it works in your favor: higher weekly mileage built up slowly goes with lower injury risk. And the book's chapters on warning signs and recovery teach you to catch trouble early. A small ache that lingers from one run to the next often comes before an injury that stops you, and the runner who backs off for it loses a few days instead of a few weeks.

What happens when you miss a day?

In most weeks, six or seven runs leave very little slack. When a cold or a hard week at work takes some of them away, there's almost no empty day to move a workout into. The plan doesn't help you choose what to keep, either. It doesn't put the week's runs in order of importance, and it has no rule for a missed week, whether to repeat it, skip it, or fold its work into the days that follow.

What it does give you is room inside each day. Nearly every run is a range, and the book tells you to take the low end when you're tired, so a rough week can shrink without falling apart. Friday is already a choice between an easy run, cross-training and a day off, and in the lighter weeks Monday is too. The book also lets you skip or move a key workout on a day when your body clearly isn't ready.

And it teaches you to judge effort. McMillan's 4 training zones, and his habit of asking which runner showed up today, help you read your body rather than chase a number on your watch. Over 12 weeks, that judgment is what lets you bend a plan like this. Most runners will protect Thursday and Sunday first and let an easy run go, but the book leaves that call to you.

Will it get you ready for race day?

Yes. By race day, you'll have rehearsed the marathon many times over.

The long run does the core work, because for the marathon nothing shorter or faster can stand in for it. Here it starts at 14 to 20 miles and climbs to the plan's summit in week 9: 90 to 105 minutes of steady running on Tuesday, 10 to 13 miles at goal pace on Thursday, and a long run of 22 to 28 miles on Sunday. Arrive at that week fresh, and it's the best marathon rehearsal in the plan.

The ranges are there to be used. For most runners, the middle of each one is plenty. Picking 28 because it's printed there is how a strong block turns into a tired one.

For most marathoners, race pace sits below threshold, roughly the effort you could hold through a one-hour race. So the goal-pace miles teach you the race itself, but they do less to lift the threshold underneath it. The plan covers that with tempo runs, steady runs and fast-finish progressions in every block, and threshold improves with work done close to it.

From week 10, the plan comes down. Week 10 keeps its progression run, a tempo and a fast-finish long run. Weeks 11 and 12 fall away to short runs and a final 12-miler, and a 1-to-3-week taper is one of the best-supported ways to race faster.

Three of the fast-finish long runs can be swapped for a 10K or half marathon tune-up race. Tune-ups don't reliably improve marathon times on their own, though early evidence suggests they may help you pace the race better.

Are the workouts varied enough?

Yes. The hard days change from week to week.

Across 12 weeks you'll run hill repeats, fartlek surges, progression runs, steady runs, tempo runs, 800-meter repeats and long runs at goal pace. In 3 of the weeks you also choose the kind of long run: steady, with surges, or alternating between paces. That range matters, because mixing easy running with clearly hard sessions builds endurance better than running everything at one moderate effort.

The easy running stays easy, too. About 85 percent of the plan is easy, and the hard days are spread across the week with easy running between them. Keeping the 2 kinds of day clearly apart is what lets the hard days do their job.
