Running Plan Review Runner's World Break 2:00 Half Marathon Training Plan

Does it build you up smartly?

Yes. Ten weeks is a short build, and this one spends them well.

Well-built training turns toward the race as it goes. Shifting the emphasis over the weeks tends to beat training that never changes, and most coaches move to race-specific work in the final stretch. This plan does that in a single block. Wednesday's fast repeats run from week 1, and from week 4 every other Sunday adds a stretch of comfortably hard miles that grows from 3 to 6, so the back half of the plan is full of work that looks like the race. It never names its phases, and at this length it hardly needs to.

What the plan does well is spell things out. Every hard session lists the warm-up, each repeat, the recovery after it and the cool-down, and most of them say what the session is for. On any Tuesday, you know exactly what tomorrow will ask of you.

Does it protect you from injury?

Partly. The plan adds mileage carefully, but it leaves strength training off the calendar and says nothing about the aches that can come before an injury.

Strength training first. The plan mentions it, but no session ever appears on the schedule, so finding a slot that doesn't crowd Wednesday or Sunday is your job. That's a real gap, because strength work lowers the risk of sports injury, and does it better than stretching or balance work. Marathon great Eliud Kipchoge built gym work into his training. "In my mind the gym work helps to chase away the injuries and train the muscles," he once wrote. On this plan, you'll have to find that time yourself.

The plan's nearest word on backing off is in its speed notes: don't overdo it, and know that some days you won't hit the paces perfectly. That's a kind line, but it stops short of telling you what a lingering ache means. A niggle, the low-grade soreness that stays with you between runs, may raise the risk of an injury that interrupts training, though so far that has been measured in footballers rather than runners. Taking a day or two off when one shows up costs far less than the weeks a full injury takes.

What the plan does give you is a gentle build. 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 this plan keeps its steps small. The mileage rises a few miles at a time, the long run never grows by more than 2 miles, and no new kind of hard work arrives in a big week. The 2 hard days never sit back to back, Monday after the long run is always a day off, and every speed session opens with 2 easy miles.

It never steps back, though. Once the mileage climbs, it stays up until the taper, with no lighter week anywhere in the build. The hardest week is week 8: ten fast 400s on Wednesday and 6 hard miles on Sunday, on legs still carrying the 13-mile long run from the week before. Training that piles up without relief tends to raise the risk of injury and illness, and a plan you follow on your own needs that relief written in. "High-intensity training does have a negative effect," said Peter Snell, who won three Olympic gold medals under coach Arthur Lydiard, "if you don't allow the body to recover." A lighter week ahead of that stretch is the relief this plan leaves out.

What happens when you miss a day?

Ten weeks leaves little room to make up lost time, and most runners lose a few days somewhere. When that happens, a good plan tells you which run to protect, which to let go, and how to pick up again.

This plan leaves those calls to you. Nothing puts Wednesday's speed session ahead of Sunday's long run, or the other way around, so in a short week you're guessing which one to keep. Nothing covers a missed run, a missed week, or a return after time off. The schedule assumes every week goes as printed.

The schedule does have slack in it, and that helps. Thursday's run is optional, cross-training can stand in for any optional easy run, and with 2 days off most weeks, there's usually an open day to move a run into. The plan is clear about who it's for, so you know before week 1 whether you're ready. And it describes easy runs and the Sunday hard miles by feel: a pace you could talk at, and a 6 or 7 out of 10.

But the speed sessions come with a printed pace and nothing else. Those paces are set for the goal, not for where your fitness is today, and they don't change as the weeks go by. The plan admits that some days you won't hit them, but it doesn't say what to do then: slow down, cut a repeat, or call it a day. One rough Wednesday isn't a verdict on the goal, though. Former elite marathoner and coach Jo Wilkinson, asked whether one workout can predict a half marathon time, said "the best indicator of race times is training as a whole." So judge the goal by how your weeks add up, not by one session.

Will it get you ready for race day?

Yes. The plan builds the fitness a half marathon asks for, and it times that fitness well.

A half marathon is mostly a test of how long you can keep up a strong, steady effort. Coach Kevin Hanson, whose Michigan team has produced two Olympic marathoners, said it of his elite runners: "I don't need to make them faster. I need to take the speed that's already in them and enable them to carry it over a longer period of time." A sub-2:00 half asks the same of you, at 9:09 a mile for 13.1 miles. For most recreational runners, half marathon pace sits below threshold, the comfortably hard effort you could hold for about an hour, so threshold work and race-pace work are different kinds of training, and no study shows one beats the other. Runner's World's approach is to train a little above race effort and build that work steadily.

This plan does that on Sundays. From week 4, every other long run carries a block of comfortably hard running in the middle: 3 miles, then 4, then 6 by week 8. You start it after 2 or 3 easy miles, so you learn to hold a hard effort on legs that have already done some work. Wednesday's repeats add faster running every week, right through race week. In week 6 you can swap the Sunday run for a 5K race, which makes a useful check on how your fitness is coming along.

The distance is covered too. The long run climbs to 13 miles in week 7, three weeks before race week, so you'll have run nearly the full race distance before you line up. Then the last 2 weeks ease off, and race week holds about half the running of the biggest week. A taper of up to 3 weeks improves race performance compared with training straight through.

Are the workouts varied enough?

Runners with some training behind them tend to improve more when easy days are truly easy and hard days are clearly hard, rather than everything settling at a medium effort. "Many recreational runners feel like they must go hard every time," says sport scientist Stephen Seiler. Those runners, he says, "improve initially, but then they stagnate."

This plan keeps that line clean. About 80 percent of the running is easy, and the hard running comes in 2 forms that feel very different: Wednesday's fast repeats, with a jog or a walk between each, and Sunday's long, steady block of comfortably hard miles.

Wednesday changes shape every week. One week it's 8 repeats of 400 meters. Another, it's a pyramid that climbs from 400 meters up to a full mile and back down. Week 8 is ten 400s in a row. With the speed held fixed, as the sample week shows, the variety is in how long you hold it. The plan teaches one gear, and teaches it well.

But the variety stops there. There are no strides, no hills and no drills anywhere in the 10 weeks. Strides take only a few minutes at the end of an easy run, and explosive work such as jumps and sprints can make running cost less energy, though strides themselves haven't been tested that way. "I do strides on my easy days after my run," said trail runner and author Morgan Sjogren. "This reminds my body to run fastest at the end of a workout or race, practice good form, loosen up any tightness and prime my body to run fast the next day during my workout." Here, adding them is up to you, and Tuesday's easy run, the day before the speed session, is a natural spot.
