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

Does it build you up smartly?

The long run is already 105 to 135 minutes in week 1, so the plan's stages show up inside the runs, not in their length. Week 5's long run ends with 15 to 25 minutes at tempo effort. Weeks 7, 9 and 11 end with miles at goal pace. Tuesday follows the same idea: a long progression run whose fast finish grows from 15 minutes to 20. The order is sound. Hills and fartlek come first, then threshold and goal-pace sessions, then goal pace on tired legs, and the taper falls where it should. Building in stages like this produces better races than holding one load throughout.

Where the plan comes up short is rest. Weeks 4 and 8 are lighter. Monday becomes optional, Tuesday's hard session turns into an easy run with optional strides, the other easy runs get shorter, and week 4's long run drops to 90 to 105 minutes. But Thursday's goal-pace session stays in both weeks, week 8 keeps its 14 to 18 mile long run, and the next week climbs to a new high. A runner who comes out of week 8 feeling refreshed is the exception. That matters, because lighter weeks are when fatigue clears and recent training sinks in. The book itself allows a down week every 4th week, so you're free to make weeks 4 and 8 truly easy. The schedule just doesn't do it for you.

The sessions on the schedule are also bare. A day reads as a number of repeats and a recovery jog, with no word on how hard to run them or why they're there. The book explains every type of workout and its purpose, but in another chapter, so the schedule alone won't tell you.

Does it protect you from injury?

Partly. The plan avoids sudden spikes, but the weeks after each lighter week and the missing strength work are its weak spots.

Many running injuries follow a sharp jump in training, especially a week far above what your body has handled over the past month. This plan never comes near that kind of spike. And for runners who already run high mileage, that volume tends to protect them, as long as it was built gradually.

But the climbs come in bursts. Coming out of week 4, you go straight to a week bigger than any before it, and that same week brings the plan's first threshold intervals. Week 9 repeats the pattern: out of a lighter week and into the biggest week of the plan. Mileage is only part of what loads your body, so a new kind of hard session in a bigger week asks more of your legs than the miles alone suggest.

Strength training is the clearest gap. The book includes a sample routine and points you to a full program online, but none of it appears on the schedule, so finding room for it around two hard days and a long run is your job. Strength training lowers injury risk more than stretching or balance work alone. Warm-ups are the same story: the book covers them, but the hard days on the schedule don't list one.

The book does help you read your body. It gives guidance on warning signs and on recovering between hard days, and it tells you to take the easy end of a range when you're tired. That's good advice, since a nagging, low-grade ache often comes before an injury that stops you running. A runner who loves volume is the runner most likely to push through one. Read that guidance before week 1, not after the first ache.

What happens when you miss a day?

This plan's answer to a rough week is built into how it's written. Nearly every run is a range: 50 to 70 minutes, 8 to 12 repeats, 14 to 18 miles. The book tells you to take the low end when you're tired, and it lets you skip or move a key workout when a day goes wrong. Friday is already a free choice between running, cross-training and rest. And because the workouts are set by effort, using zones tied to your own fitness rather than fixed numbers, a hard session still fits on a tired morning.

But it stops short of a plan for when things go really wrong. It hints that the long run and the key days matter most, but it doesn't put them in order, so in a short week you're guessing what to keep. There's no rule for a missed week either, and the schedule is printed, so it can't change on its own. With runs on 6 or 7 days, there's little open space to move a session into. Whether you repeat the week, skip ahead or fold the work into the days that remain, the rearranging falls to you.

Will it get you ready for race day?

Yes. By race day, you'll have run goal pace in pieces, in one long piece, and at the end of 15 miles.

Threshold fitness comes from running at threshold effort, and from week 4 on, every week has a threshold or goal-pace session. Goal pace gets a thread of its own, and it grows: 3 repeats of 3 miles in week 4, 2 of 4 miles in week 8, then 6 to 8 miles unbroken in week 10. Alongside it, the long runs in weeks 7, 9 and 11 end with 2 to 4 miles at goal pace on tired legs. For a runner who fades when the pace turns hard, that's the work that makes race pace feel familiar instead of something to survive.

The long runs are built for an endurance runner. They're 105 to 135 minutes from the first week and reach 14 to 18 miles by week 6, so 13.1 will feel short. The plan takes your distance as a given and puts the race-specific work inside it. The longest run comes two weeks before race week.

The finish is right too. The running drops over the last 2 weeks, and race week is about a third of the peak. A taper of 1 to 3 weeks improves race performance by 2 to 6 percent compared with training straight through.

Are the workouts varied enough?

Yes. You'll run 7 different kinds of hard session, and the easy days stay easy.

Runners improve more when easy days and hard days are clearly apart, and a mix of easy running and clearly hard sessions builds endurance better than long stretches at a steady, moderate effort.

This plan does both. Hill repeats, fartlek, progression runs, goal-pace repeats, threshold repeats, tempo runs and long runs with a fast finish all appear, and the repeat formats change almost every time they come back. About 87 percent of your running is easy. The hard days fall at least 2 days apart, except in race week, when a short fartlek and a short tempo run land back to back.

If you want more quick running, strides are the simplest addition. The plan offers them as an option with the easy run in weeks 4 and 8, and short, fast efforts like these improve running economy and time-trial performance. A handful after an easy run once or twice a week fits into any week here.
