Sub 40 Minute 5K Pace Guide
A sub 40 minute 5K means averaging 8:00/km (12:52/mile). This is a brilliant first goal if you are new to running or coming back after a long break — and it is completely achievable with a run-walk approach. Here, finishing is the win, and 8:00/km is gentle enough to leave plenty of room for walking breaks along the way.

How to pace it.
Run-walk intervals
You do not need to run the whole way to break 40 — you need to keep moving and average 8:00/km. A simple, repeatable run-walk pattern is the smartest tool: try a few minutes of easy running followed by a short walk, and repeat it the whole way. The key is that your running segments are relaxed, not rushed, so you can keep the pattern going to the finish. Start conservatively, settle into the rhythm, and let the kilometres add up. Walking is part of the plan, not a failure — and crossing the line under 40 minutes is something to be genuinely proud of.
What blows it up.
Trying to run the whole 5K too quickly, blowing up early, and then having to walk much more than planned.
Setting off at the pace of the runners around you instead of your own easy effort.
Treating walk breaks as a sign of failure rather than a deliberate, effective strategy.
Skipping the run-walk structure and just going by feel, which usually starts too fast.
Comparing your time to experienced runners — your race is against the 40-minute mark, nobody else.
Adjust for the course
Same idea, different terrain.
Sub 40 is 8:00/km — a realistic and rewarding first 5K target for new runners and run-walkers.
Run-walk is a proven method; many people complete their first sub-40 5K mixing both.
Parkruns welcome walkers and run-walkers, with a friendly tail-walker at the back so nobody finishes alone.
Choose a flat, simple route for your first attempt to keep the effort predictable.
Hydrate normally beforehand and wear comfortable, broken-in shoes — no special fuelling required.
5K pace — FAQ
What pace is a sub 40 minute 5K?
About 8:00 per km, or 12:52 per mile — gentle enough to include walking breaks.
Can I break 40 minutes with run-walk?
Absolutely. A steady run-walk pattern with relaxed running segments is one of the best ways to do it.
Is sub 40 a good goal for a beginner?
Yes. It is realistic, motivating, and a genuine achievement for someone new to running.
How should I structure my run-walk?
Pick a pattern you can repeat the whole way — for example a few minutes running, then a short walk — and keep the running easy.
Do I need to train fast to hit it?
No. Consistent, easy run-walk sessions a few times a week are enough to build up to a sub-40 5K.
