Running Plan Review Runner's World Break 4:30 Marathon Training Plan

Does it build you up smartly?

It does, with two loose ends. The hard work changes once, at week 6, in a way that makes sense, but the plan never explains its phases, and a few sessions leave the details to you.

A marathon build usually works best in stages. Easy running lays the base, harder work follows in a planned order, and race specific running comes last. Shifting the emphasis from block to block tends to beat holding the same training throughout, though the edge is small. Arthur Lydiard, the New Zealand coach who made this order famous, was often asked which stage mattered most. His answer, his foundation recalls, was "Everything," often followed by a question: "Who would want to eat a cake half-baked?" In this plan, too, the early easy weeks count as much as the big ones.

This plan names 3 phases and makes one real shift between them. Through week 5, the hard work is Wednesday's track session and a long run that grows. From week 6, tempo runs join on alternate Sundays, a turn toward the steady, sustained effort the race asks for. Wednesday stays a track session from week 1 to week 16, and every repeat, from one lap to a full mile, runs at nearly the same speed. But nothing in the PDF says what each phase is for, or why the work changes when it does.

What the plan gets right is how fully it writes the sessions. The track and tempo sessions are laid out clearly: how far to warm up, how many repeats and how long, the recovery between them, and a line on what each workout is for. Some give a range, such as 4 to 6 repeats, which leaves the last call to you on the day. The hill Fridays are looser, a distance on a hilly route with the rest left open.

Does it protect you from injury?

Sudden jumps in running tend to raise injury risk, most clearly when a single run goes well past your longest of the past month. And many injuries that look like slow wear seem to start suddenly, often right after one such run. This plan protects you well on most counts, but its long runs keep stepping past what came before, and strength work is left to you.

The long run weeks are the ones to watch. In weeks 3, 5, 7 and 11, the week's running rises by a fifth or more, and each time it's because the long run grew. Week 11 is the steepest: the long run goes to 18 miles, Tuesday's easy run stretches from 4 miles to 6, and the week's total rises by nearly a third. Measured against the month before, none of these weeks is a spike. But they land every other week through week 7, before the first lighter week arrives. Ultrarunning coach Cliff Pittman puts it plainly: even if research shows runners can build faster than the old 10 percent rule allows, "that doesn't mean it's automatically safe to increase weekly volume by 20% or 30%." For a runner whose shins or Achilles have complained after a new longest run, these are the weeks to run carefully.

Strength is the second gap. The PDF never brings up strength work, so when to do it, and what to do, is up to you. This gap counts, since strength training lowers injury risk more than stretching or balance work alone. Marathon great Eliud Kipchoge once wrote about his training that "the gym work helps to chase away the injuries and train the muscles." On this plan, that gym work is yours to add, so decide where it goes before week 1.

The PDF says little about warning signs beyond the talk test and a reminder not to overdo the track. A small ache that hangs around between runs may raise the odds of a real injury, though that link has so far been measured in footballers rather than runners. Most coaches still treat the first twinge as the time to back off, not to grit through Sunday's run.

To its credit, every track and tempo session opens with 2 easy miles, and no hard day ever follows another. Lighter weeks fall in weeks 8, 12 and 14, too. On a printed plan that matters, because training that piles up without a break tends to raise the risk of injury and illness, and a scheduled lighter week is the simplest way to build one in. The Sundays that swap the long run for tempo don't count as lighter weeks, because they shift the effort from distance to speed rather than lowering it.

What happens when you miss a day?

Sixteen weeks is long enough for something to go sideways: a missed Wednesday, a sore calf in week 9, a long run that has to wait. When it happens, this plan gives you some room, but not much guidance.

The room comes from the optional runs. Thursday's short run, and Monday's in the later weeks, can become rest or cross training without touching the rest of the week, and the PDF says so. That leaves 4 runs carrying each week. The PDF doesn't say which of those to protect in a short week, though the long run and the track session read as the key ones.

The guidance is what's missing. The PDF doesn't say what to do after a missed week, a skipped long run, or a few days sick: whether to repeat, skip ahead, or ease back in. That call is yours.

The bigger issue is the paces. Every target is printed for the goal, and it stays the same from week 1 to week 16. If the goal is a stretch for you, every Wednesday starts out too fast. If you're already fitter than the goal, the targets stop pushing you halfway through. And since every repeat in the plan sits at nearly one speed, a target that's wrong for you is wrong on every Wednesday at once. The talk test for easy runs and the 6 or 7 out of 10 for tempo help, but nothing tells you how to check whether the printed targets fit you, or how to change them. Training adjusted to the runner tends to match or beat a fixed template. Here, that adjusting is left to you. "Every training plan is written in pencil," says Chris Bennett, Nike Running's global head coach. "They're meant to be erased and adjusted." With this plan, you hold the eraser, and the Wednesday targets are the first place to use it.

Will it get you ready for race day?

Mostly, yes. The plan builds the endurance a marathon needs and the right kind of speed for this goal. The weak spot is the last 3 weeks.

The plan never asks for a mile at goal pace before race day. Every hard mile, on the track or at tempo, is faster than goal pace, and every easy and long mile is slower. The PDF's reasoning is that tempo miles run faster than goal pace make race day pace feel easier. For most runners aiming at this goal, marathon pace sits well below threshold, the effort you could hold for about an hour, so tempo running and race-pace running are different kinds of training. Either is a reasonable choice, and no study shows one beats the other. This plan picks tempo, growing it from 2 miles in week 6 to 6 miles by week 10. Coaches who favor goal-pace work point to race day itself. "Grooving your goal pace keeps you from going too fast too early in the race," writes coach Greg McMillan. On this plan, the tempo Sundays build the fitness, but the feel of goal pace is something you'll find on race morning.

Endurance is the other half. Early evidence ties longer long runs to faster marathons, though no study has tested whether shorter, harder sessions could do the same job. Here the long run reaches 20 miles in week 13, three weeks before the race, and the biggest week of the plan, about 44 miles, lands the same week. Both are the right size for the goal.

But the taper eases the miles more than the work. After the 20 mile run, the long runs shrink, yet Wednesday stays at 10 to 11 miles in weeks 14 and 15, and week 14 ends with a 5K race or a 12 mile run. Then race week drops by about two thirds at once. A taper that cuts the running over the last 1 to 3 weeks, while keeping some faster work, improves race performance over holding training steady. This one keeps the hard work full until the final week, so you may stand on the start line with more of the last month still in your legs than you'd like.

Are the workouts varied enough?

Yes, in shape if not in speed. The track sessions change form almost every week: short repeats one week, a ladder of mixed lengths the next, mile repeats later on, with tempo runs on alternate Sundays from week 6. Close to 80 percent of the running stays easy, and no hard day follows another. Mixing mostly easy running with a few clearly hard sessions tends to build endurance a little better than long stretches of steady, moderately hard running, and this plan keeps that split.

But the small, fast work is missing. Nothing in the plan runs faster than the Wednesday repeats: there are no strides, short sprints or drills. Strides are a handful of relaxed, fast pickups tacked onto the end of an easy run, over before you get tired. They cost almost nothing, and short, explosive efforts can make running a little more efficient, though results are mixed and strides themselves haven't been tested directly. They would add the one gear this plan never touches. Coach Jay Johnson, author of Simple Marathon Training, wants them in a marathon build from the first weeks. He writes that "you need to rev the engine with strides, at 5k pace or faster." Here, a few after an easy run each week would be yours to add.
