Workouts for the 1.5 Mile Test: Which Sessions to Run and When

You know you need to train for your 1.5 mile test, but you're not sure which workouts actually belong in that training. The test demands two things from you simultaneously: enough aerobic capacity to sustain a hard pace for over a mile, and enough leg speed to make that pace feel manageable. Neither one alone will get you through. You need both. And that means your training has to include more than one type of workout.

There are five workout types that form a complete 1.5 mile test training plan. Below, I'll explain what each one does, how hard it should feel, and how often to use it. The order matters too — I've structured this in the order you should introduce each session as your training builds.

Easy Runs: Your Aerobic Engine

Easy running is the foundation of everything. I'd estimate it should make up 70–80% of your weekly mileage — and yes, that holds even when you are training for a 1.5 mile test. This seems counterintuitive to most people who figure a short, fast test requires short, fast training. It doesn't. A strong aerobic base is what stops you from blowing up in the final 400 metres, when your lungs are screaming and your legs are starting to argue with you.

Easy pace means genuinely easy — slow enough that you could hold a full conversation without gasping. Aim for 20 to 45 minutes per session. Don't drift into that uncomfortable middle zone where it's neither easy nor hard. That mushy effort trains nothing well.

Frequency: 2–4 times per week.

Strides: Speed Without the Fatigue

Strides are short, progressive accelerations tacked onto the end of easy runs. Start at easy pace, build gradually over 20–25 seconds to about 90% of your top speed, then decelerate over the final 5 seconds. Walk or jog easily for 90 seconds between each, and do four to six per session.

They will not make you tired. Done correctly, strides sharpen your neuromuscular coordination — your legs relearn what fast feels like, so that your target test pace stops feeling like a sprint. Do them twice a week and you'll notice a difference within two to three weeks. No track required. Any flat 80–100 metre stretch works fine. Also check out the running strides page for more info.

Frequency: 2 times per week, added to the end of easy runs.

Interval Training: Running at Test Pace, Repeatedly

Intervals are the most specific training you can do for the 1.5 mile test. The goal is simple: run at about 5k pace, repeatedly, with structured recovery in between. Running 12 × 400 metres at 5k pace with 90 seconds of rest between each repetition is the gold standard. It teaches your body — and your mind — what that effort feels like when you are already fatigued.

Two rules to follow. First: always include a warm-up of at least 5–8 minutes of easy jogging before you begin. Jumping straight into intervals from cold is a reliable way to pick up a niggle. Second: your interval pace should be one you can sustain for all your repetitions. If your times slow significantly from the first rep to the last, ease back or take more rest. Doing half your reps at the right pace is better than doing all of them sloppily.

You might not be able to do 12 x 400m immediately. Start with 6 x 400m or 8 x 400m and build up from there. As your fitness builds, move from 400m repeats to 800m repeats. Longer intervals at test pace develop a deeper kind of endurance that pays dividends in the second half of the test. See how to choose between 400m and 800m repeats for the 1.5 mile test for a full comparison.

Frequency: At most once per week.

Tempo Runs: Aerobic Strength at Threshold Effort

Tempo runs sit between easy pace and interval pace — a comfortably hard effort you could theoretically sustain for about an hour in a race. It should feel like work, but controlled work. You are pushing your lactate threshold upwards — the point at which your body starts to accumulate fatigue faster than it can clear it.

My strong advice: do not run a single prolonged tempo effort. Break it into intervals instead — 3 × 8 minutes with 90 seconds of easy jogging between each, or 4 × 5 minutes. You get the full training stimulus without the mental grind of one unbroken 25-minute effort. I do all my threshold training in intervals and I'd encourage you to do the same. See how long your tempo run should be for the 1.5 mile test for specific duration guidance at different fitness levels.

Frequency: At least once per week.

Goal Pace Running: The Most Specific Work You Can Do

Goal pace running is exactly what it sounds like. You run at the precise per-kilometre (or per-mile) pace you need to average on test day. Not slightly faster, not slightly slower — that exact pace. Start with short repetitions: 4 × 400m at goal pace with 90 seconds rest. Work up to 6 x 400m. Progress week by week to 3 × 800m, then 2 × 1200m. By the final weeks of training, you should be able to hold goal pace for close to 2.4 kilometres in a single effort.

When test day arrives, goal pace will feel familiar rather than frightening. That familiarity is worth more than you'd think.

Frequency: Can be incorporated into your interval sessions, or run as a standalone session once per week in the final 4–6 weeks of training.

How to Combine These Workouts

The most common mistake is stacking hard sessions back to back. Hard days need easy days on either side. A sensible training week for the 1.5 mile test looks something like this:

• Day 1: Easy run + strides
• Day 2: Interval session (400m or 800m repeats)
• Day 3: Easy run or rest
• Day 4: Tempo effort
• Day 5: Easy run + strides
• Day 6: Rest or very easy jog
• Day 7: Easy or rest

You do not need all five workout types from week one. In the first three to four weeks, stick to easy runs, tempo runs and strides only. Add another tempo run after that. Then add some intervals. Goal pace work folds in naturally as your interval sessions progress. Rushing the build-up is the single biggest mistake I see in runners preparing for this test.

A Note on Hill Running

Hills are not in the list above because they are not a separate category — they are a tool you can apply to your easy runs or as a standalone session. Short hill repeats of 60–90 seconds build leg strength and aerobic capacity simultaneously, and they make flat running feel considerably easier. If your test takes place on flat ground, hills still help. See what hill workout helps most for the 1.5 mile test.

Frequently Asked Questions

How many days a week should I train for the 1.5 mile test?

Three to four days a week is the sweet spot for most people. More than that without a solid base behind you tends to generate fatigue and injury faster than fitness. Consistent training across two to three months will do more than six hard weeks of overtraining and then limping to the start line.

When should I add speed work to my training?

Not in week one. Give yourself three to four weeks of easy running, tempo runs and strides first. I know it feels slow, but the base you build in those early weeks is what allows the speed work to stick. Add intervals too early and you will either get injured, get stale, or both.

Should I use all five workout types every week?

No — at least not at the start. You work up to the full menu. In the first month, easy runs, tempo runs and strides. In month two, add intervals now and then. By month three, you have the full range available: easy runs, strides, intervals, tempo, and goal pace work. Each layer adds something the previous ones couldn't provide on their own.

How do I know if I'm running my intervals at the right pace?

Work backwards from your target test time. If you need to run 1.5 miles in 12 minutes, that's 8:00 per mile or ~5:00 per kilometre. Your interval pace should be within ~5 seconds per kilometre of that. If you cannot sustain that pace for all repetitions, you are running too fast — not too slow. Consistency across all reps matters more than the speed of any single one.
