Running Plan Review Run Less, Run Faster 3Plus2 Novice Marathon Training Program

Does it build you up smartly?

This plan puts its workouts in a sensible order, but the last weeks of the build don't turn toward the marathon itself.

What the plan does well is give each run a job and keep it there. Tuesday is speed, Thursday is sustained hard running, and Saturday is distance. The hard work also moves through stages: shorter track repeats paired with tempo runs early on, then longer repeats, then the same pattern again through the middle weeks. The plan doesn't label these blocks, but you can feel them as you go.

The trouble comes late. Coaches tend to shift training toward race-specific work as the race comes near, and here the mix barely changes. Through weeks 9 to 14, Tuesdays stay at 5K pace and most Thursdays at 10K pace, and the tempo run reaches marathon pace only once, in week 12.

But the schedule lists each session without saying why it's there. The book explains what each of the three runs is for, in detail, while the schedule gives you a distance and a pace and nothing more. Keep the book close in the first weeks, until the purpose of each run is second nature.

Does it protect you from injury?

Injury risk tends to climb after a sudden jump in training, most clearly a single run that goes well past your longest run of the past month. This plan mostly avoids that mistake, but it leaves you on your own in four places that matter.

The good part first. Your 3 runs never fall on back-to-back days. Every run has a day of rest or cross-training on each side of it, and 2 of your 5 weekly sessions take the pounding out of the week entirely. The weekly running also grows without any sudden leap.

But the miles are denser than they look. The weekly total tops out at 30, and nearly every one of those miles has a pace attached. Weekly distance alone doesn't capture how hard you're training, and until race week there's no run in this plan where you just jog. Mile for mile, this is demanding training, whatever the weekly total says.

The breaks are few, too. The running only truly eases off twice, in weeks 13 and 15, after the hardest training is already done. Before that, the shorter Saturdays in weeks 7 and 10 look like breaks, but the Thursday tempo run gets longer in those same weeks, so your legs don't get much of a rest. Training that piles up without relief tends to raise the risk of injury and illness, and on a fixed plan, a lighter week written into the schedule is the simplest relief there is. That matters most in a first marathon build, because fitness tends to arrive within a few weeks, while bone takes months to catch up. By the middle of the plan, your breathing may tell you you're ready for more while your legs are still catching up.

But strength training is missing from the schedule. The book has a full strength program in a chapter of its own, and none of it appears on the calendar, so finding room for it around 5 sessions a week is your job. That's a real gap, because strength work substantially lowers injury risk in sport.

Nothing on the schedule mentions warning signs either, but they matter here. Early evidence suggests a niggle, a small ache that hangs on from one run to the next, can be the first step toward a full injury that stops your training, though it comes from other sports rather than running. The calendar never tells you to ease off when one shows up, and with a pace on nearly every run, it's tempting to push through.

What happens when you miss a day?

The plan's paces don't bend, and that's its main weakness when a week goes wrong.

Every run but race week's short easy one comes with a target pace from the book's tables, and nothing else: no effort to aim for and no heart rate to watch. On a morning when your legs are heavy or the route is hilly, the plan asks for the same number, and it gives you no other way to tell whether you got the run right. The schedule also doesn't say which session to keep in a short week. The book makes clear the 3 runs come before the cross-training, but if only one run fits, choosing it is up to you. In the middle weeks, when Saturday is building toward 20 miles, that's usually the one to protect.

But the book's rules for reshuffling are simple and generous. You can move days around as long as two runs don't land back to back, and with Friday and Sunday open, there's usually room. A missed workout, or even a missed week, can simply be dropped. If you'd like more running, you can add one or two easy runs. And your paces aren't frozen at the 5K time you started with. They move up after a faster race, or once all 3 runs start to feel easy.

Because the book takes the time to explain what each run is for, you'll know what you're trading when you move one. That makes the gaps in the schedule easier to fill on your own.

Will it get you ready for race day?

Yes. Race day is where this plan is at its best.

A marathon is mostly a test of whether your legs can keep going long after they want to stop, and most coaches build for it with the long run. Marathoners who train with longer long runs tend to finish faster, though no study has tested whether shorter, harder sessions could do the same job. Here the long run climbs from 8 miles to 20, and the 20 comes in week 12, four weeks before the race, with 18-mile runs in weeks 11 and 14. In those biggest weeks, Saturday's run is longer than the rest of the week's running combined.

The midweek work fits the race too. Most Thursdays work right around threshold, the line between hard running you can sustain and hard running you can't. For most runners who aren't racing near the front, that effort and marathon pace are different kinds of training, and either one is a reasonable way to prepare.

Race pace gets its own rehearsals as well. Two tempo runs, in weeks 2 and 12, are 5 miles at marathon pace, and the long run a week before the race is 13 miles at that pace. You go into race week knowing what the effort feels like.

A peak of about 30 miles a week is plenty for a first marathon.

Are the workouts varied enough?

A week of running usually works best when the easy runs are truly easy and the hard ones are clearly hard. Mixing mostly easy running with a few clearly hard sessions may build endurance better than steady, medium efforts, though the edge in studies is small.

The hard running here has real range. The Tuesday track session is never the same two weeks in a row, from a ladder that steps down from 1200 m to 400 m to 2 sets of 6 × 400 m. Thursday moves between short, fast tempo runs, longer steadier ones, and runs at marathon pace.

The easy side of the week is where the plan makes its trade. Pierce and Murr replace easy runs with two cross-training days, and their reasoning is that cross-training builds your aerobic fitness while cutting the impact that leads to injury. But until race week, no run in this plan is run by feel. Apart from warm-ups, cool-downs and one 3-mile run in race week, each run has a pace target, the long run included. Easy running is the base that carries the harder training, and here that base moves mostly to the bike or the pool.

But the schedule leaves off strides, the handful of short, fast, relaxed accelerations that many runners tack onto an easy run. They cost almost nothing in fatigue, and many runners use them to practice running fast while staying relaxed. You'll need to add them yourself.
