Running Plan Review Pete Pfitzinger Advanced Marathoning Multiple Marathoning, 10 Week

Does it build you up smartly?

Mostly. The stages suit a plan built for the weeks between two marathons, but the hard block works more on speed than on the race itself, and the schedule doesn't name or explain its phases. Training that changes its emphasis over time tends to beat training that never changes, and world-class coaches shift toward race-specific work as the race nears.

This plan's stages fit its job. A marathon leaves your legs damaged and your fitness high, so the first three weeks ask for nothing but short recovery runs, steady runs and a few strides. Only when the legs have had time to mend does the hard work start, and it is aimed at sharpening fitness you already have, not building it from scratch. That work is mostly 5K-effort repeats and tune-up races, so the weeks before the taper train speed more than marathon running.

The repeat sessions leave nothing to guess. Each one tells you how many to run, how far, at what effort, and how long to jog before the next, with a warm-up before and a cool-down after. Most hard days also say what they're for, so you start each one knowing what it should do for you.

Does it protect you from injury?

Not as well as it prepares you to race. Injury protection is this plan's weak spot, and the risk peaks in week 4.

Sudden jumps in running load tend to raise injury risk, most clearly when a single run goes well past your longest of the past month, and weekly jumps above about 30% are a warning sign too. And many injuries seem to start suddenly, often right after one run that goes well past your recent longest, rather than building up gradually.

Week 4 is that kind of week. After three weeks of nothing but easy running, Tuesday opens with hill sprints, and by Sunday you've added a long midweek run, the plan's only threshold run and your first 16-miler since the race, on about 15 more miles than the week before. It all lands about a month after you ran 26.2.

There is a fair case for it. You were running this much only a couple of months ago, and Pfitzinger puts it simply: "The body's quite good at getting back to a level it's done before." Beyond that, higher mileage, built up gradually, tends to go with lower injury risk, not higher, though that evidence comes from watching runners rather than from trials. But the body tends to adapt on a staggered clock. Blood and muscle energy systems respond within a few weeks, while tendons take weeks to a few months and bone takes months. By week 4 you may well feel ready before your legs actually are. Between marathons, the trap is mistaking that feeling for permission, and stacking fatigue on legs that are still rebuilding.

The strength work is missing from the calendar. The book lays out a full strength program in its own chapter, but none of it is scheduled, so when and how often to fit it in falls to you. It deserves a place in your week, since strength training substantially lowers the risk of sports injuries. Physical therapist Dan White puts the payoff in racing terms: "If we can decrease the time away from running, that's the win. If strength training buys you consistency and health, that buys you seconds." With a second marathon ten weeks out, staying healthy is most of the job, so put the book's sessions on your own calendar.

The book explains how to spot overtraining and illness, but it gives no step-by-step return for a specific injury. So the three recovery weeks are yours to read. Notice whether an ache from race day is fading or staying, because early evidence, so far from footballers rather than runners, suggests a niggle that lingers may raise the risk of an injury that stops you running altogether. Sports medicine doctor Brett Toresdahl draws a simple line between soreness and injury: "If it's in the joint and not in the muscle that's a problem." If that's where a race-day ache still sits as week 3 ends, get it looked at before week 4 piles on the miles.

What happens when you miss a day?

A ten-week plan has very little slack. Lose a week and you've lost a tenth of the whole thing, with no time later to make it up.

The book gives you a firm rule for that. Miss fewer than 10 days and you simply pick the schedule back up. Miss 10 to 20 days within 8 weeks of the race and it's time to rethink your goal. Miss more than 20 and you rethink it regardless. In this plan, you're inside that 8-week window from week 3 on, so a long break after the recovery weeks almost certainly means changing what you're aiming for.

But for a squeezed week, the kind where you can fit in four runs instead of six, there's no list of what to drop first. The book ranks what matters most in general: endurance and the long run first, then threshold work, then the 5K-effort repeats, then speed. Turning that into a decision about this Tuesday and this Sunday is left to you.

Smaller disruptions are easier. Every day's distance comes as a range, and that range is permission: on a heavy-legged day, run the low end and it still counts. Monday is always open, which gives you somewhere to move a run. And the book teaches you to train by effort, not just the number on your watch. It gives a heart rate range for every kind of run except the fastest speed work, and it sets the threshold run in minutes rather than miles, so slower and faster runners get the same dose. When your legs are off, you still know what each run should feel like. Co-author Scott Douglas writes of his own running: "Some days, I plan to go hard or long but what I encounter once out there merits doing otherwise; other days, I discover I should aim higher, and adjust subsequent days…" A few weeks after a marathon, expect more of the first kind of day, and let the ranges and the open Mondays absorb them.

Will it get you ready for race day?

Yes, as long as the marathon you just ran counts as part of your preparation, which is how the plan is built.

The long runs are the backbone. Five Sundays in a row, from week 4 to week 8, you head out for 16 miles or more, building to a 19 to 20 miler in week 7. That peak comes three weeks before race day. Early evidence links longer long runs to faster marathon finishes, and while no study has tested whether shorter, faster sessions could do the same job, this plan doesn't ask them to. After the peak, the last three weeks step down, and a taper of up to 3 weeks improves race performance compared with training straight through. Taper researcher Iñigo Mujika sets a wide range: "Our studies indicate that an efficient taper may last between one and four weeks." The best length, he says, "depends on each athlete's adaptation and recovery profile." You tapered for your first marathon only weeks ago, so you already know how your legs answer to rest. Use that here.

What you won't find is much running at marathon pace. There are 2 miles of it in the whole plan, in a short run during race week. The plan's reasoning is carryover: you just spent a whole race at that pace, and the rhythm is still in your legs. The research leaves room for that choice. For most runners who aren't elites, marathon pace sits below threshold, roughly the effort you could race at for an hour, so threshold work and race-pace work are different kinds of training, and no study shows one beats the other.

The hard days lean somewhere you might not expect. The book ranks threshold work above 5K-effort repeats, yet this plan has one threshold run against five repeat sessions. The likely reading is that the plan counts on the threshold work from the months before your first marathon and spends these ten weeks on the faster end instead. The repeats go after it.

The two tune-up races fit the same thinking. No study has tested whether races like these change marathon finish time, though there's a hint that racing helps you pace a marathon better, and they're a good check of how far your legs have come back.

Are the workouts varied enough?

Yes. The plan mixes a lot of easy running with several different kinds of hard work, and that mix is a sound one.

Roughly 86 percent of your running here is easy, and the hard days always have easier days between them. Runners who keep easy days easy and hard days hard may improve more than runners who drift into a steady medium effort every day. Sport scientists Stephen Seiler and Espen Tønnessen call that drift "a typical training error committed by recreational athletes," a slide into what they named a training intensity "black hole." The book gives this plan's recovery runs a heart rate ceiling, which helps keep you out of it. The hard days change shape from week to week, from short fast repeats to a sustained threshold run to a race. Set against all that easy running, clearly hard days like these may build endurance a little better than long stretches of steady, moderately hard running.

Strides show up from week 2 on, in most weeks of the plan, and week 4 adds a set of 10-second hill sprints. They take only a few minutes at the end of an easy run. Strides themselves haven't been tested, but short, explosive work can make your running more economical. After a marathon, they're also the first runs that ask your legs to move quickly again.

The schedule is easy to read, too. Each week sits in its own column counting down to the race, and every day names both the kind of run and how far.
