PACR
AI 10K training plan, rebuilt every morning.
The 10K has nowhere to hide. It is fast enough that your pace targets have to be right and long enough that you cannot bluff the aerobic work. PACR sets both from your own sessions, then rewrites the week around the runs you actually did.
intervals
How a 10K block is built.
Eight to twelve weeks, two quality days, and a long run that exists to hold the whole thing up rather than to be impressive.
Easy volume plus strides, so the first hard session in week four does not arrive on legs that have only jogged. One steady run a week keeps the aerobic side ticking.
Cruise intervals and tempo running — 5 × 6 minutes, or 25 minutes continuous — at a threshold pace read off your own sessions. This is where most 10K time actually comes from.
Race-specific reps: 5 × 1 km at 10K pace with short recoveries, then 6 × 800 m slightly quicker. The goal is for goal pace to feel like a gear, not a gamble.
Volume halves, one short session at race pace stays. You arrive under-raced rather than over-cooked.
What a 10K week looks like.
A representative sharpening week. Two hard days with real recovery between them, and easy days that are actually easy.
Run the Saturday parkrun hard and the plan knows: Sunday's long run comes back slower, and Tuesday's reps get rewritten around the effort you already spent.
What decides today's 10K session.
Rebuilt at 4am from what you ran, what you can hold, and what the air is doing to it.
Your last run
Split drift across the reps and how hard the final one felt. Five kilometres of intervals on Tuesday is a real cost, and Thursday's session is written knowing what it took out of you.
Your real pace
10K pace sits a few seconds either side of threshold for most runners. PACR models threshold from your own sessions, so the rep target moves in seconds as you get fitter instead of staying where a calculator left it.
Today's climate
Interval pace is the first thing heat destroys. The session carries an offset in seconds per kilometre, so 28°C changes the target rather than turning a good workout into a failed one.
Reps, counted for you.
Interval sessions fall apart in the first thirty seconds of a rep and in the last one. The coach is there for both.
10K training questions.
What runners ask when they want a faster 10K and are not sure what to change.
How long does it take to train for a 10K?
Eight to twelve weeks for a runner who already runs a few times a week; longer if you are starting from scratch. PACR sets the block from your race date and your current sessions, then rewrites each day as you go.
How do I break 50 minutes for a 10K?
Fifty minutes is 5:00 per kilometre, so the work is making 5:00 feel comfortably aerobic rather than desperate. That means threshold running most weeks and race-pace reps close to the race — which is exactly what the block is built around.
How many interval sessions a week should I do for a 10K?
Two quality sessions a week is plenty for almost everyone, and one is enough in a heavy work week. PACR will not stack a third onto a week your last runs say you cannot absorb.
What pace should I run 10K intervals at?
Close to goal race pace for kilometre reps, a little quicker for shorter ones. PACR takes those targets from your own threshold rather than from a predicted time, and adjusts them for the day's heat.
Is a 10K plan suitable for beginners?
Yes, provided you can already run for about twenty minutes. The block starts from your current volume and grows it, rather than dropping you straight into interval sessions your legs have not earned yet.
Does it work if I only run three days a week?
It does. Three days means one quality session, one steady run and one long run, with the coach protecting the easy day rather than filling it. Consistency across eight weeks beats a perfect week you only manage twice.
Training a different distance?
Same coach, same daily rewrite, different block.
