A 10K training plan built on the Norwegian method

Most 10K plans are built around a weekly track session that leaves you flat for two days. A Norwegian-style plan keeps the hardest efforts small and controlled, puts a lot of work at threshold, and fills the rest of the week with easy running. For a race that takes most runners somewhere between 30 and 70 minutes, that mix fits well.

In practice, spend about 70 to 80% of your training time in Zone 1, put most of the rest into Zone 3 (threshold), and add one short VO2max session in the middle of the build. Train by heart rate rather than pace, so a hot day or a hilly route does not turn a threshold session into a race.

Why threshold matters for a 10K

The 10K is raced close to your lactate threshold. For a well-trained runner, race pace sits a little above threshold. For a newer runner taking an hour or more, it sits close to it or a touch below. Either way, the pace you can hold just before lactate starts to pile up decides most of your result.

Marius Bakken and later the Ingebrigtsen family built their training around large amounts of controlled threshold work, often split into intervals so they could stay at the right intensity for longer without tipping over. Jason Culp describes this in The Norwegian Method. The goal is to accumulate time at threshold while staying fresh enough to do it again two or three days later.

How it differs from polarized training

People often lump the Norwegian method in with polarized training, but they are different models. Polarized training, from Stephen Seiler's research, keeps most sessions easy and puts most of the remaining work well above threshold, with very little in the middle. The Norwegian approach puts the hard work right at threshold, which is the middle zone polarized training avoids, and keeps work above threshold to a small slice. Both agree that most of your running should be easy.

Your zones for this plan

StartLane uses four zones based on percentage of max heart rate:

• Zone 1 (60 to 75%): easy running, long runs, warm-ups. You can talk in full sentences.
• Zone 2 (75 to 82%): steady aerobic running, used sparingly in this plan and mostly on cross-training days.
• Zone 3 (82 to 90%): threshold. Comfortably hard. You can say a few words, not a paragraph.
• Zone 4 (90 to 96%): VO2max. Hard, and reserved for the 4x4 session.

For a runner with a max heart rate of 190, Zone 1 is about 114 to 143 bpm and Zone 3 is about 156 to 171 bpm. In threshold intervals, aim for the lower half of Zone 3 early in the plan. Heart rate lags at the start of each rep, so judge the second half of the interval rather than the first minute.

The shape of the plan

Here is how a longer block is laid out.

Foundation

The first phase sets your easy pace and starts building threshold volume. A typical week:

• Monday: easy run, 25 to 35 minutes
• Tuesday: threshold intervals, 3 to 5 reps of 4 to 5 minutes in Zone 3, 3 minutes jog between
• Wednesday: easy cycling, 30 to 40 minutes
• Thursday: easy run, or a second short threshold session once you are a few weeks in (6 x 2 minutes)
• Friday: rest
• Saturday: long run in Zone 1, 40 to 50 minutes
• Sunday: easy cycling

The cycling adds aerobic work without the pounding of another run, which matters if you are not yet running six days a week.

Build plus VO2max

Once threshold work feels routine, add the 4x4 VO2max session. Tuesday stays as threshold, now 5 reps of 5 to 6 minutes with shorter recoveries. Thursday becomes the 4x4, four 4-minute efforts in Zone 4 with 3 minutes of active recovery between. The long run grows to about 55 minutes.

That is the only session above threshold each week, and it holds 16 minutes of hard work. Our full guide is here: The 4x4 VO2max Workout.

Peak

The last training phase is the heaviest. Keep the 4x4 on Thursday and run two threshold sessions, a longer one early in the week (4 x 6 minutes) and a shorter, slightly faster one later (8 x 2 minutes with 1 minute jog). If anything slips, cut the extra volume and keep the easy runs easy.

Recovery weeks

Every fourth week, volume drops by about a quarter to a third. You still run a short threshold session, around 3 x 4 minutes, so the rhythm stays in place. Feeling good is not a reason to skip these weeks, since the recovery week is usually why you feel good.

Taper and race week

A longer block ends with two taper weeks. The first is lighter, with one threshold session and a shorter long run. Race week has a short threshold session early in the week, a rest day, and a 20-minute easy run the day before. More detail is in How to Taper for a Race.

How hard should threshold feel

This is where most runners go wrong. You should finish each threshold rep feeling like you could do one or two more. If your heart rate keeps climbing through the top of Zone 3 by the third rep, slow down. If you are gasping at the end, you ran a VO2max session by accident.

Your last rep should be about the same pace and heart rate as your first. If it is much slower, or your heart rate is much higher at the same pace, you started too fast. Culp makes the same point about the Norwegian runners: part of what made the system work was holding back on days when they could have run faster.

Common mistakes

Easy days tend to creep up. If your easy runs sit in Zone 2 or Zone 3, you will not have the legs for threshold sessions. See Why You're Running Too Hard on Easy Days.

Threshold reps are not time trials, so racing them misses the point. You are after time in the zone, not the fastest split. Adding a second VO2max session usually costs more than it gives, and one 4x4 a week is enough.

Heat and hills raise heart rate. Let pace slow and keep the heart rate where it belongs. Finally, two threshold sessions in a week is a peak-phase load, so build up to it with several weeks of single sessions first.

What a 10K race looks like after this plan

Go out at a pace you know from your threshold reps, slightly quicker if you are a fast runner, and hold it. Many runners who train this way find the middle of the race feels familiar, because they have spent weeks at that effort. Save anything harder for the last mile.

Don't watch heart rate closely during the race. It will drift upward late on, and that is normal. Use it in training, then race on feel and pace.

How StartLane handles it

StartLane builds 5K and 10K plans. Choose 10K and enter your race date, and the app sets the plan length, anywhere from 4 to 16 weeks, with base, build and peak phases and a taper of 1 to 2 weeks built in. Your heart rate zones come from your max heart rate, and easy, tempo, interval and race paces are estimated from your race PR. Each session shows its heart rate target and pace, and a coach can override an individual workout with a reason and a note.

The plan does not change on its own if an athlete misses a week or gets sick. If that happens, repeat the previous week rather than jumping ahead. Daily check-ins help you see how each runner is handling the load.
