Running Plan Review Greg McMillan Half Marathon: Intermediate-Advanced (Speedster)

Does it build you up smartly?

In parts. The training comes in a smart order, but the schedule never prints a lighter week until the race is close, and its sessions come without a reason attached.

A plan that changes its focus from block to block usually races better than one that piles on the same load every week, and McMillan's order makes sense for a Speedster. The hills and short surges of the first 3 weeks build strength and leg speed, the work this runner already does well. Goal pace repeats arrive in week 4, alongside longer hard efforts. From week 7, goal pace grows into long, unbroken stretches, and the long runs finish with it.

McMillan gives you a lever here: the book lets you take a down week every fourth week. Use it. But the schedule itself doesn't print one, and its first real lighter week is week 11, just before the race. That gap matters, because an easier week every few weeks lets built-up fatigue clear so the training can sink in. A runner who follows the printed weeks straight through gets 10 weeks of steady pressure.

The sessions are clear on what to run, but not on why. The schedule gives the repeats and the jogs between them, and leaves the purpose of each workout to the book's workout chapter, so read it before you start.

Does it protect you from injury?

Mostly, yes. This plan does more right than wrong on injury, with one hard stretch to plan for.

The basics are sound. The 2 hard days never sit next to each other, and in most weeks the running grows a little at a time. That matters, because sharp jumps in weekly running raise injury risk, and steady growth keeps you clear of them.

But weeks 5 and 6 are a real step. In week 5, the total running rises by about a fifth, and for the first time 3 days in one week ask for hard work. In week 6, the long run reaches 14 to 16 miles. That's long, steady load, the kind a Speedster's legs have had least of. Your fitness responds to it quickly, but tendons adapt more slowly than muscle, and without a lighter week first, they meet the step already tired. Taking the book's fourth-week down week before it is the simplest protection. If an ache lingers from one run to the next in these weeks, let Friday be a rest day, because a niggle like that appears to raise the odds of an injury that actually stops you running.

The book also asks for strength work, but none of it is on the schedule. It includes a sample routine and points you online for the full program, and finding days for it around the hard sessions is your job. That's a real gap, because strength training substantially lowers the risk of sport injuries. The hard days also print no warm-up, but adding an easy one before each is up to you.

What happens when you miss a day?

Day to day, yes. Across a lost week, no.

This plan bends easily on a normal week. Nearly every run is a range, 50 to 70 minutes or 5 to 7 repeats, and the book tells you to take the low end when you're tired. On a bad day, it lets you skip a key workout or move it. The book's four effort zones, adapted from McMillan's mentor David Martin, teach you to train by feel, so you're not chained to a number on your watch. You're the coach on the day, and the book gives you the tools for it.

Your paces can keep up with you too. In weeks 7, 9 and 11, the plan offers a 5K or 10K tune-up race in place of the long run. Run one, put the result into the calculator, and your training paces and goal move with your fitness.

But a missed week leaves you on your own. The schedule has no rule for coming back from one. And while the long runs and hard days clearly matter most, the plan doesn't say which to keep when only one fits.

Will it get you ready for race day?

Yes. It gets the half marathon right.

A Speedster's races tend to go wrong in the second half, when the effort has to be held rather than spent. What holds it is your threshold: the dividing line between a hard pace you can keep up and one that soon forces you to slow. Half marathon pace sits close below that line, and threshold improves when you train at that effort. Every week of this plan includes running at or near it.

Goal pace running grows with patience, almost the opposite of what a Speedster would design for themselves. In week 4, you run 2 or 3 repeats of 3 miles at goal pace. In week 8, it's 2 repeats of 4 miles. In week 10, it's one unbroken run of 6 to 8 miles. By then, holding goal pace is something you've done many times, not something you're hoping for.

The long run reaches 14 to 16 miles in weeks 6, 8 and 10, past the race distance each time. Alternating with those, in weeks 7, 9 and 11, are long runs that end with 2 to 4 miles at goal pace. For a Speedster, those are the most useful runs in the plan: they teach you to run strong late in a race, when your legs are already tired.

Weeks 11 and 12 ease back, and race week is short, with a few brisk repeats on Wednesday to keep you sharp. A taper of 1 to 3 weeks improves race performance by 2 to 6 percent compared with training straight through, so you arrive at the race rested.

Are the workouts varied enough?

Racing fitness grows best from mostly easy miles with a range of truly hard work mixed in. Easy running paired with intervals and fartlek builds endurance better than long stretches of steady, medium-hard running, and keeping easy days truly easy is what lets the hard days be hard.

McMillan's plan follows that pattern closely. Over the 12 weeks you'll run one-minute surges, longer fartlek efforts, hill repeats, mile repeats, shorter fast repeats, longer efforts near threshold, runs that speed up at the end, and steady miles at goal pace. Fartlek comes back on Tuesdays through week 11, so the speed a Speedster relies on never fades. Around 5 of every 6 miles are easy, which keeps the variety from turning into fatigue.

Few weeks look the same, and for a runner who gets bored by repetition, that's a real pleasure.
