Running Plan Review Greg McMillan 5K: Intermediate-Advanced (Combo)

Does it build you up smartly?

Strong plans are built in stages. Each stage gives your body a main kind of hard work, and the next builds on it, so the hardest, most race-like work lands on a body ready for it. Training built in blocks like this leads to better races than training that keeps the same emphasis week after week. Good plans also ease off every few weeks, so the work has a chance to settle in.

There's a lighter week in week 8, but it's the only one before race week. Weeks 1 to 7 hold about the same amount of running, and the first week is nearly as big as the biggest. That's 7 weeks in a row close to full size.

The page also gives you less than it could. Each day names the workout, the number of repeats and the jog between them, but not the warm-up, and not what the session is for. Both are elsewhere in the book, so following the plan well means reading well beyond the schedule.

The order of the hard work makes sense, even without names on the stages. And the one lighter week is well placed. It's where the first time trial sits, so you test yourself on fresher legs.

Does it protect you from injury?

Partly. The plan gets the basics of safe training right, but it leaves 2 protections to you.

The first is strength training. McMillan recommends it, with a sample routine in the book and a fuller program online, but the schedule never makes room for it. Strength training lowers the risk of sport injuries substantially, more than stretching does, and 2 sessions a week is enough for most runners to get the performance benefit too. The runner most exposed here is the one who treats every printed day as a run day and never adds any.

The second is time to absorb the work. 7 weeks pass before the first lighter one, and after it, only race week eases off. Lighter weeks every few weeks let built-up fatigue clear, and they're linked to fewer injuries than adding load week after week. The book allows a down week every fourth week, so you can take more breaks than the page prints. But you have to choose to, and the schedule won't remind you.

Everything else here protects you well. Hard days always have an easier day between them. New kinds of hard session arrive in ordinary weeks, never in a week where the running also grows, and the load never spikes far above the weeks before it. The 3 open days give your legs room whenever they ask for it.

The book also teaches the warning signs of injury and what to do about each. A low-grade ache that hangs around between runs appears to raise the risk of a real injury, so treat the first one as a reason to ease off, not something to run through.

What happens when you miss a day?

Week 11 shows why flexibility matters. It holds 3 hard sessions, and if 2 days of it disappear, the page doesn't say which session to keep.

That's the gap in this plan. The book suggests the long run and the key sessions matter most, but it never ranks a week's runs for when days go missing. And after a whole lost week, nothing says whether to pick up where the calendar is or step back to where you left off.

What the plan does give you is room. Monday, Wednesday and Friday are already open: run easy, cross-train or rest. Easy runs come as ranges of minutes, and the book tells you to take the low end when you're tired. On a bad day, it lets you move a key workout or skip it. And the whole method rests on effort, so each day's running is set by how you feel, not by what the page expected of you.

Will it get you ready for race day?

Yes, with 2 soft spots near the end.

A 5K is run near the top of your aerobic range, for long enough to hurt. Getting faster at it takes practice at race effort, and a higher threshold underneath it. Threshold is the line between hard running you can keep up for a long while and running that fades fast, and it rises when you train at that effort. Because 5K pace sits close to a physiological limit for most runners, practice at race pace earns its place.

This plan covers both. Race pace repeats run all through it, starting in short pieces and later stretching longer. Threshold work comes in several forms, from short repeats with brief jogs to Sunday runs that finish fast. And the 2 time trials show you what goal effort feels like when it isn't broken into pieces.

The first soft spot is the long run. It never goes past what this level asks of you on day one, and from week 10, Sundays belong to time trials and race pace repeats. For a 5K, that length is plenty. But the longest runs all come in the first 7 weeks, so the endurance they build has to last.

The second is the taper. Race week is far lighter than the biggest week, which is right. But the week before it carries 3 hard sessions, the last of them race pace 400s on Sunday, 7 days out, so all the freshening up has to happen in one week. Runners race 2 to 6 percent faster after a taper of 1 to 3 weeks than after training straight through, and one week is the short end of that. Go into week 11 knowing it's harder than it looks, because time on your feet doesn't show how much the fast running takes out of you.

Are the workouts varied enough?

Yes. This is the plan's strongest side.

A mix of easy running and hard intervals builds more endurance than steady, medium efforts run day after day, and runners tend to improve more when easy days stay easy and hard days are clearly hard. This plan keeps that split, and its hard days rarely repeat. Race pace repeats come in 4 different lengths. Hill repeats in weeks 5 and 7 build power, and short sprints later on build speed. The 2 time trials test all of it.

Strides come on Tuesdays in weeks 2, 6 and 10, growing from 8 to 20. Short, fast efforts like these make each stride cost a little less energy. Twenty in one session is a lot of quick running in small doses, and it lands just as the plan turns toward race day. Few Thursdays feel like the one before, and that keeps 12 weeks interesting.
