How to Run a Faster Mile: Goal Splits and a 6-Week Plan
To run a faster mile, train at the pace you are trying to race, broken into 400 meter repeats. Everything else on this page exists to support that one session.
That means you need a target time before you need a workout. The target sets your 400 meter split, and the split is what every session below is built on.
Below are the splits for every goal time from 6:00 to 12:00. After that come the two sessions that do the work, the six week plan, and how to pace the mile itself.
Start with a target time, not a workout
Pick the time you are chasing, then find it in the table. A mile goal only becomes trainable once you know what it feels like over one lap.
| Goal mile time | 400 m split | 800 m split |
|---|---|---|
| 6:00 | 1:29 | 2:59 |
| 7:00 | 1:44 | 3:29 |
| 8:00 | 1:59 | 3:59 |
| 9:00 | 2:14 | 4:28 |
| 10:00 | 2:29 | 4:58 |
| 11:00 | 2:44 | 5:28 |
| 12:00 | 2:59 | 5:58 |
One detail worth knowing before you time yourself. Four laps of a 400 meter track is 1,600 meters, about nine meters short of a mile.
Add two to three seconds to your four lap time and you have your real mile.
If your goal sits between the rows, or you train in kilometers, the running time calculator will convert any pace for you.
The session that actually moves your mile time
Repeats of 400 meters at your goal split, with a jog recovery as long as the repeat. Run a 2:00 split, jog 2:00. That is the whole rule.
- Start at six repeats and build to ten over the six weeks. Volume comes second to hitting the split.
- Every repeat should be the same time. If the last one drifts more than three seconds slow, you ran the early ones too fast.
- Jog the recovery, do not stand still. Standing lets your legs cool and the next repeat feels harder than it should.
The split is the workout; the repeat count is only volume.
This works because it teaches your body a specific pace. Race pace stops being an unfamiliar effort you have to guess at and becomes something your legs already recognize.
If you cannot finish six repeats on the split, the goal is too fast for now. Move one row down the table and come back to it.
The second session, and what tempo really means
Threshold pace is the fastest pace at which your body clears lactate about as fast as it produces it. Run faster than that and it starts to accumulate.
For most recreational runners it sits close to the pace they could hold for about an hour. In practice it is comfortably hard: you can get a few words out, not a sentence.
One point the internet still gets wrong. Lactate is a fuel your muscles burn, not the waste product that makes them ache. That older story has been out of date for years.
The session itself is simple. Run four minutes at threshold, jog ninety seconds easy, and repeat.
Comfortably hard is the whole instruction.
Start with three reps and build toward five reps of five minutes. It raises the pace you can hold before you start to fade, which is what a fast mile runs on.
Easy running is the base the hard sessions stand on
One easy run a week, at a pace where you could hold a conversation. It is not filler. It is what lets you recover enough to hit the splits in the next session.
Be clear about what this run does and does not do, because this is where most mile advice goes wrong.
Adding easy distance builds the engine. It will not, on its own, drop your mile time. A plan that only adds miles is a plan for a longer race.
Volume supports the mile. Goal pace trains it.
The 6-week plan
Three sessions a week with a rest day between each. Every 400 is run at your goal split from the table above.
| Week | Speed | Threshold | Easy run |
|---|---|---|---|
| 1 | 6 × 400 | 3 × 4 min | 20 to 30 min |
| 2 | 7 × 400 | 4 × 4 min | 25 to 35 min |
| 3 | 8 × 400 | 4 × 5 min | 30 to 40 min |
| 4 | 6 × 400, 2 s faster | 4 × 5 min | 30 to 40 min |
| 5 | 10 × 400 | 3 × 5 min | 25 to 35 min |
| 6 | 4 × 400 | rest | 20 min + time trial |
Week 6 is deliberately light. Run the four repeats early in the week, then rest. The fitness is already built, and the only job left is to arrive fresh.
Warm up before every session with ten minutes of easy jogging.
Cold legs cannot hit a split.
How to pace the mile itself
You can do six weeks of correct training and still lose the time in the first sixty seconds. Almost everyone goes out too fast.
Even splits win the mile.
- Lap 1: no more than two seconds faster than your split. It will feel far too easy. That feeling is the point.
- Laps 2 and 3: exactly on the split. This is where the race is won, and where it feels least like winning.
- Lap 4: everything left. If you paced the first three correctly there will be more there than you expect.
A first lap five seconds too fast is never given back. It is paid for in the third lap, usually with interest.
What matters less than you think
Three things get far more attention than they earn.
- Running every day. Frequency without intensity does not sharpen a mile. There are good reasons to try running a mile a day, but a faster mile is not the main one.
- Rebuilding your form. Not overstriding and staying tall are worth a few seconds. A full technique overhaul during a six week block usually costs more than it returns.
- Chasing a weight number. Rules of thumb about seconds per pound get repeated a lot and are not something to build training around. Eat enough to complete the sessions.
The two sessions in the plan are worth more than all three of these combined.
Where to go from here
If a continuous mile is still the hurdle, the speed work can wait. Build the distance first with the four week plan for running a mile without stopping, then come back here.
Once you have a tested time, you will want to know where it sits. Whether a 10 minute mile is good depends on your age and how long you have been running.
The idea that easy running makes you faster deserves its own read. You will find why it works in running slow to run fast, and the vocabulary behind all of it in what pace means in running.
Pick a split. Train on it. Test it in six weeks.
