Running Plan Review Greg McMillan 10K: Advanced (Endurance Monster)

Does it build you up smartly?

McMillan counts Arthur Lydiard among his mentors, and the shape of this plan shows it: build the engine first, sharpen it later, and keep the long run going the whole way through. Training that shifts its focus in stages like this outperforms training that stays at one level from start to finish. Easier weeks belong in the build too. A lighter week every few weeks lets fatigue clear, so the work of the weeks before can turn into fitness.

McMillan gets both right. Hill repeats and long steady runs open the plan. From week 4, the hard days move to threshold running and then to repeats at 10K goal pace, which grow longer as the race gets closer. The book builds in a down week every 4th week, and this plan keeps it, in weeks 4 and 8, before 2 weeks of taper.

But none of this is spelled out where you'd see it each day. The stages have no names, and each day shows only the workout. Thursday of week 1 reads as 10 to 12 hill repeats of 60 to 75 seconds with a jog down, and nothing about what they're for or how they should feel. That lives in the book's chapters on each kind of run. If you like to understand a session before you run it, keep the book close for the first few weeks.

Does it protect you from injury?

Mostly, yes. But strength is left entirely to you, and week 5 needs care.

The plan does the big things well. There's always an easier day between hard ones. Mileage rises a little at a time, and the down weeks in weeks 4 and 8 give your legs a break before the next block. That matters at this volume: for many runners, most weeks land around 50 to 60 miles.

Strength is the gap. The book includes a sample routine and points you to a full program online, but none of it appears on the schedule. Fitting it around the hard days and 5 to 7 runs a week is your job. It deserves the slot, since strength training cuts the risk of sport injury substantially, more than stretching does.

Week 5 brings a new kind of hard work into the biggest week of the plan. The first repeats at 10K goal pace, 6 or 7 of them a mile long, arrive alongside 80 to 90 minutes of steady running on Tuesday and a progression long run on Sunday, straight after the first down week. The rise in mileage isn't extreme. The new session is what makes the week heavier than its mileage suggests, since distance alone undercounts how hard a week is; pace and intensity add stress of their own. Starting with 6 repeats rather than 7 is a sensible way in.

The book does teach the warning signs and how to respond, and that counts for a lot. A small ache that keeps coming back appears to raise the chance of an injury that interrupts training, so knowing when to back off is real protection. One more thing to add yourself: the book asks for a warm-up before hard sessions, but the schedule doesn't print one.

What happens when you miss a day?

Partly. The plan gives you plenty of room on a bad day, but little help after a lost week.

McMillan writes for runners with jobs and families, and it shows. Easy days are ranges of minutes, and the book tells you to take the low end when you're tired. Monday and Friday can be a run, cross-training or rest. On a bad day, you can move a key workout or skip it. Every session is set by effort, in 4 zones adapted from his mentor David Martin, so you can trust your legs when they disagree with your watch. Effort zones tied to your own physiology are a sound way to set how hard to run, and the mid-plan time trials keep your paces current.

But a lost week is another matter. Those open Mondays and Fridays make it easy to shift a single run. They don't tell you which work to save when several days go. In the second half, a week can hold three hard days, a progression run on Tuesday, goal-pace work on Thursday and a fast finish or time trial on Sunday, and the book doesn't rank them. Nor does it say whether to repeat the lost week or move on. Those calls fall to you.

Will it get you ready for race day?

A 10K is run close to your limit from the first mile to the last. Race-pace practice pays off most when race pace lands near one of the body's physiological limits, and most coaches treat 10K pace as sitting close to one of them. That's why the best 10K preparation spends plenty of time at that pace, with threshold work behind it.

This plan builds exactly that. The goal-pace sessions start in week 5 with 6 or 7 single miles. By week 11, about ten days before the race, they've become 3 repeats of 2 miles. Every one of these sessions adds up to about the full race distance at race pace. What grows is the size of the pieces, so the pace you'll race at becomes something you've held for 2 miles at a time, again and again.

Behind them sits threshold work: steady and tempo runs from week 2, and repeats of 2000 meters in weeks 6 and 10. Threshold rises when you run at threshold, and this plan returns to it all the way through.

Endurance is more than covered. Long runs of 90 to 120 minutes and progression runs with a fast finish give you far more stamina than 6.2 miles asks for. The last 2 weeks ease off, with race week cut by more than half, and tapering for 1 to 3 weeks before a race tends to make runners a few percent faster.

Are the workouts varied enough?

Yes. Across 12 weeks you'll run hills, steady runs, tempo runs, tempo repeats, progression runs, goal-pace repeats, time trials and a fartlek.

Easy running makes up most of a runner's mileage, and it's the base that lets harder work sink in. Mixing it with clearly hard sessions builds endurance better than long stretches of steady, moderately hard running. About 85 percent of this plan's running is easy, so the hard days stand out as hard.

The mix leans one way, and for an Endurance Monster that's the question worth asking. A 10K rewards sharpness, the side this runner finds hardest. This version puts most of its hard running at 10K goal pace or a little slower, in long pieces, and gives faster running smaller doses: hill repeats in weeks 1 and 3, stride sessions on 3 Tuesdays, in weeks 2, 6 and 9, and a fartlek of 1-minute surges in race week. It does more to make race pace feel steady than to add a faster gear. If the faster gear is what you lack, protect those Tuesdays and hill days. Strides take little out of you, and short, fast efforts like these make your running more economical.
