18-minute 5K essentials

What pace do you need to run a 18-minute 5K?

Exactly 18:00 requires an average of 3:36/km or about 5:48/mile. This plan targets 3:35/km (5:45/mile), giving you a small racing buffer while building the speed and endurance needed to hold it.

Race Threshold
3:36/km · 5:48/mile
The average pace for exactly 18:00.
Plan Target
3:35/km · 5:45/mile
A small buffer so race day does not depend on perfect pacing.
Training Week
6 runs in build weeks
The recovery week cuts the load to 2 runs.
Training Period
8–12 weeks
Repeat the four-week block two or three times.
Suggested Race Splits

These use the plan's 3:35/km target and leave a small margin around the goal.

Your PB progression

See where this plan sits in the 5K ladder.

Use the easier step if this target feels too large. Once this pace is repeatable, the faster plan becomes the next sensible PB target.

Reset

Absorb and reset

Reduce impact while keeping one controlled tempo insertion.

Session Guide

What each session is doing

Breakeven sessions maintain and support. Breakthrough sessions move the target forward.

Target Pace

5:45/mile / 3:35/km

The pace you need to run close to 18 minutes.

Treadmill equivalent10.4 mph / 16.6 km/h
400m split86s at race pace
800m split2:52

Breakeven sessions

These maintain fitness, support recovery and prepare you for the breakthrough sessions.

Steady / easy runEasy running should be by feel and no quicker than 7:45/mile. Focus on recovery and form.
Long runSlow and steady, generally less than an hour of work.
FartlekUnstructured speed play. Use it to practise changing gears without obsessing over exact splits.

Breakthrough sessions

These are the hard sessions that move you toward the target. Treat them as mini-milestones, not ego tests.

400m repsRun around 84 seconds per 400m at roughly 5:35/mile pace with 60 seconds standing recovery.

Quick Answers

5K training plan questions

Clear answers on pace, readiness and how to adapt the plan without mangling its purpose.

What pace do I need to run a 18-minute 5K?

Exactly 18:00 is 3:36/km or about 5:48/mile. The plan targets 3:35/km or 5:45/mile to provide a small buffer.

How many days a week should I run?

The full build weeks contain 6 running days, including deliberately easy running. If you need to remove a day, drop an easy run first and preserve recovery between the quality sessions.

How long should I follow this plan?

Use the three build weeks and one recovery week as a repeatable block. Most runners should allow eight to twelve weeks, completing two or three blocks before their target race.

What current 5K time should I have before starting?

Best suited to runners with a current 5k PB under around 20 minutes.

Which sessions matter most?

The race-pace repetitions develop your target 5K rhythm. Easy runs and the long run build the aerobic support, while the recovery week lets the training take effect.
