The 10 km training plan, built around your race date and your pace

First 10 km or a new personal best, the recipe fits in three lines: plenty of easy running, one or two fast sessions a week, one slightly longer run. What changes from one runner to the next is the paces and the volume. You give your race date and the days you're available: Trainetic works out the rest, for free.

The five rules of 10 km race prep

They come up in every published plan, from the French Athletics Federation (FFA) to Hal Higdon's programs. They are also the rules your plan applies.

Allow 8 to 12 weeks. That's the length of most published plans. Your plan starts from your race date and fits itself to it, taper included.

Three sessions a week is the foundation. That's the median seen among recreational runners preparing for a race under 21 km. Two sessions are enough to finish; the third makes room for the long run.

Most of your kilometers are run slowly. At a pace where you can talk. That easy volume is what builds endurance; the fast sessions come on top of it, not instead of it.

Two hard sessions never come back to back. At least two days between two quality sessions: recovery is when your body absorbs the work and gets better.

The long run stays reasonable. For a 10 km, it doesn't need to go beyond 1 h 20. Reference plans cap it at a share of the week's volume, around 20 to 30 %.

The four paces of a 10 km plan

All of them are calculated from your maximal aerobic speed (MAS). That's why one plan doesn't suit two runners: the sessions look alike, the paces don't.

Pace	Benchmark	What it's for
Easy	About 65 % of your MAS — you can talk	Most of your volume: heart, tendons, the habit of running
Threshold	About 86 % of your MAS — short sentences	Holding a strong pace for longer: long intervals, tempo
MAS	100 % of your MAS — you can't talk anymore	Raising your ceiling: 30/30, 45/45, pyramids
10 km pace	Around 90 % of your MAS	Getting your body used to race-day rhythm, at the end of the plan

Don't know your MAS? A recent race time is enough: the plan works it out from that. Without a time, it starts from a cautious value and refines it session after session.

The three sessions of a typical week

With three slots. With two, the long run steps aside and one fast session remains; with four or more, the plan adds easy volume and, depending on your level, a second quality session.

The easy run

The foundation. You run at a pace where you can hold a conversation. It's the easiest session of the week, and yet the one that matters most.

The quality session

Threshold first, then MAS, then race-day pace as the race gets closer. Warm-up, fast blocks announced by voice, cool-down. A runner who is just starting out stays on threshold: MAS work comes later.

The long run

The longest run of the week, always at an easy pace. It grows over the plan, from forty minutes up to 1 h 20 at most for a 10 km.

And the last two weeks?

Volume drops — to 70 %, then to 55 % — but intensity stays: that's the taper, and it's what gets you to the start line fresh. The day before, a short session to loosen your legs. On race day, nothing but your race.

The five mistakes that cost you time

Running every easy run too fast. A "medium" pace on every run is too fast to recover and too slow to improve. Easy days need to be truly easy.

Ramping up volume all at once. Distance-related injuries rise when weekly volume climbs sharply. Your plan builds in four-week steps, with a recovery week at each step.

Picking a target time at random. A goal that's too ambitious makes you run every session at a pace you can't hold. If your target time is well below what your benchmarks predict, Trainetic tells you and suggests a time within your reach.

Stacking two hard sessions. The second one is run tired, so slower, and brings almost nothing. One real session beats two half sessions.

Showing up tired on race day. The urge to "do one last big session" in race week is the most costly of all. What's done is done: the last week is for recovering.

Where these numbers come from

No number on this page was picked by feel: each one comes from a public source.

The 8 to 12 weeks and three sessions are the norm in published plans, including those of the FFA. The median of three sessions a week comes from the NURMI study (Frontiers in Physiology, 2021) on recreational runners.

The long run at 20-30 % of volume is the limit set by reference plans; Hal Higdon's advanced 10 km plan stays at 16 km for 54 km a week.

The two-week taper follows the meta-analysis by Bosquet (2007): volume reduced by 41 to 60 %, intensity maintained.

The well-known 10 % rule per week has never been proven: a trial with 532 runners found no difference in injuries (Buist, 2008). Your plan works in steps.

The questions runners ask before a 10 km

How many weeks do you need to prepare for a 10 km?

Eight to twelve weeks, for most runners. Your plan fits your race date: the closer it is, the more it focuses on the essentials; the further away, the more time it takes to build your base.

How many sessions a week?

Three is the right balance: an easy run, a fast session, a long run. Two are enough to finish, without a long run. Beyond three, the plan mostly adds easy volume.

Are intervals a must?

To finish, no. To get faster, one fast session a week makes the difference. If you're just starting out, your plan begins with threshold — a strong but controlled effort — and only adds MAS work once your level allows it.

How do you break 50 minutes, or one hour?

To break 50 minutes, you need to hold 5 min per kilometer; to break one hour, 6 min. Enter your target time when you create your plan: if it's realistic, all your paces are set from it. If it isn't yet, Trainetic tells you and suggests a time within your reach.

What pace should you run on race day?

The one you trained at the end of the plan, no faster. The classic trap is getting carried away at the start: the first two kilometers run too fast are paid for in the last two.

Do you need a watch?

No. Your phone is enough: during the session, a voice announces each block, its duration and the target pace, and tells you when to slow down. If you already have a Garmin watch, the session is sent to it too.

What if I've never run before?

Then you don't start with a 10 km, but with thirty minutes of continuous running. That's what the beginner plan is for: nine weeks of alternating walking and running, and then you're ready to take on a 10 km.

Is it free?

Yes, for the essentials: creating your plan, taking it with you as a PDF, and running each session with voice guidance. A subscription is available for advanced features — automatic plan adjustments week after week, a written analysis of each session. The plan itself doesn't need it.
