Everyone starts somewhere. The runners you pass every morning all lived through their own tough first kilometre, their first breathlessness, their first heavy legs. Where you start doesn't decide how far you can go.
The C25K program (short for couch to 5K) is the most proven roadmap for new runners. In 9 weeks and 3 runs per week, this beginner plan takes you gradually from a walk-run mix to 30 minutes of continuous running. At Boréal Running, in Saint-Augustin-de-Desmaures near Quebec City, we coach beginners all the time, and this guide gathers the same advice we share during in-store fittings.
Here's what you'll find: the week-by-week couch to 5K schedule, where to add strength work, a warm-up and cool-down routine, simple nutrition tips, the mistakes to avoid, the essential gear, and a printable tracking sheet. Nine weeks is enough — as long as you follow the right path and are in good general health to begin.
What is the C25K (couch to 5K) program?
Why the run/walk method works for every beginner
The core idea of the C25K plan is simple and effective: you don't start by running flat out. You alternate running and walking intervals so the body adapts gently. Gradual progression limits stress on the joints, because the musculoskeletal system (muscles, tendons, ligaments) needs more time to adapt than the cardiovascular system. A beginner can improve their cardio in a few weeks, but knees and ankles need a slower adaptation to absorb the new loads.
Slow and steady always beats erratic effort. The most practical cue: if you can say a full sentence while running, you're at the right pace. If you can't, slow down until you can speak normally. This simple talk test prevents most pacing mistakes from your very first outings.
How many days a week should a beginner run?
The structure is clear: 3 runs per week, separated by rest days or cross-training (yoga, cycling, swimming). Adding running sessions too soon raises the risk of overtraining and injury — a well-documented reality among enthusiastic beginners who progress too fast. The body improves during rest days, not during the workouts themselves. Respecting this structure protects your long-term progress.
Add one strength session per week
Running is half the equation. Strength training is now recognized as one of the best tools for injury prevention in runners, especially beginners whose muscles and tendons are still adapting. On top of your 3 runs, add 1 strength session per week, on a non-running day (strength work isn't running — it doesn't count toward your 3 outings).
No need to overcomplicate it: basic bodyweight exercises for the legs, hips and core are plenty to start. Keep it short and consistent — consistency beats intensity. We'll dedicate a full article to strength exercises for runners; for now, just remember the cadence: once a week, throughout the 9 weeks.
Couch to 5K plan: week-by-week schedule
Each run starts with 5 minutes of brisk walking (warm-up) and ends with a cool-down. Unless noted otherwise, the 3 runs in a week are identical; in weeks 5 and 6, the three runs differ. This plan follows the standard C25K structure.
| Week | Run structure (after the warm-up) | Strength |
|---|---|---|
| 1 | Alternate 1 min run / 1 min 30 walk, for 20 min (3 identical runs) | 1 session |
| 2 | Alternate 1 min 30 run / 2 min walk, for ~20 min (3 identical runs) | 1 session |
| 3 | 2 × [1 min 30 run · 1 min 30 walk · 3 min run · 3 min walk] (3 identical runs) | 1 session |
| 4 | 3 min run · 1 min 30 walk · 5 min run · 2 min 30 walk · 3 min run · 1 min 30 walk · 5 min run (3 identical runs) | 1 session |
| 5 | Run 1: 3 × 5 min run (3 min walk between) Run 2: 2 × 8 min run (5 min walk between) Run 3: 20 min continuous run | 1 session |
| 6 | Run 1: 5 min run · 3 min walk · 8 min run · 3 min walk · 5 min run Run 2: 2 × 10 min run (3 min walk between) Run 3: 25 min continuous run | 1 session |
| 7 | 25 min continuous run (3 identical runs) | 1 session |
| 8 | 28 min continuous run (3 identical runs) | 1 session |
| 9 | 30 min continuous run — the last run is your 5K! (3 identical runs) | 1 session |

Weeks 1 to 3: building the base
The first three weeks lay the foundation. They feel easy, and that's on purpose. Don't skip steps: smart progression is what separates the runners who finish the program from those who quit in week 4.
Weeks 4 to 6: stepping it up
The continuous-running blocks get longer. The key run of week 5 — 20 minutes without stopping — is often the one beginners dread most, and the one they're proudest of once it's done. If a run feels too hard, repeat the previous week rather than forcing it. That's not failure, it's smart training.
Weeks 7 to 9: finishing strong
Continuous running climbs to 25, then 28, then 30 minutes. The last run is your 5K — celebrate it, whatever your pace. To track your progress, download our C25K tracking sheet (PDF) and check off every completed run: seeing how far you've come is powerful motivation.
Warm-up and cool-down: two habits that matter
A 10-minute warm-up before every run
The warm-up isn't optional. Start with 3 to 5 minutes of brisk walking, move into dynamic stretches (high knees, butt kicks, forward lunges), then finish with 2 to 3 minutes of very easy jogging. The whole sequence takes about 10 minutes and helps reduce injury risk. Skip static stretches before running — they relax muscles instead of activating them. Save static stretches for after the run.
The cool-down you shouldn't skip
After your run, take 3 to 5 minutes of easy walking to bring your breathing and heart rate down. Then do static stretches for your calves, quads and hamstrings, holding each for 30 to 45 seconds. Drink water right after. Five minutes now saves you a week of needless stiffness.
Common mistakes that make beginners quit
Going out too fast and ignoring your body
The number-one beginner mistake is running too fast in the early weeks. Remember the talk test: if you can't say a full sentence while running, you're going too fast — slow down. Also tell normal discomfort apart from real pain. Heavy legs and mild breathlessness are normal. Sharp pain in a knee, ankle or foot is an immediate stop sign. If it lingers after a few rest days, see a healthcare professional before resuming.
Skipping rest days and rushing the steps
Overtraining is a major cause of dropout and injury for beginners. If a run went badly, repeat the whole week instead of pushing the progression. Nobody is judging your pace: what matters is to keep moving forward, even if that means redoing week 3 twice.
What to eat before and after a beginner run
Before a run
For the program's runs (under 45 minutes), you don't need an elaborate meal. A light snack 30 to 60 minutes before is plenty: a banana, toast with peanut butter, or a simple energy bar. Avoid heavy meals in the 2 hours before to prevent digestive discomfort.
After the effort
Aim for a balanced meal with protein and carbohydrates within 2 hours of finishing: Greek yogurt with fruit, a glass of chocolate milk, or a chicken sandwich all work well. Beginners don't need gels or complex supplements — whole foods, quality carbs and steady hydration are more than enough for your 9 weeks.
The best beginner running gear (and where to get fitted)
Running shoes: the investment that prevents injuries
A well-fitted running shoe is the only truly non-negotiable piece of gear for a beginner. For pavement or a track, choose a cushioned, light and stable model. Models like the Brooks Adrenaline GTS, Brooks Glycerin or ASICS Gel-Nimbus are excellent starting points. Browse our road running shoes for men and for women, and see our guide on how to choose running shoes.
Leave a bit of room at the front, since feet spread while running. At Boréal Running, our specialists assess your gait and foot shape before recommending the right model. This fitting is offered in store — far more reliable than an online algorithm that never sees you run.
GPS watches and accessories to track your progress
A basic GPS watch like the Coros Pace is plenty to track distance, time and pace without drowning in data. A pair of wireless headphones rounds things out to keep you motivated on every run.
Join the Boréal Running Crew so you don't run alone
Running in a group changes everything, especially at the start. The Boréal Running Crew meets weekly from our Saint-Augustin-de-Desmaures store, open to all levels — including beginners in their very first weeks. Runs are announced on our Strava club and social channels. No judgment, no performance pressure: just movement and good company.

Couch to 5K: frequently asked questions
How long does it take to go from couch to 5K?
About 9 weeks, running 3 times a week, following the C25K plan. Some beginners take a little longer by repeating a week when needed — that's completely normal and still gets you to 5K.
Can a complete beginner really run 5K in 9 weeks?
Yes. The run/walk method builds your endurance gradually so that 30 minutes of continuous running becomes achievable by week 9, even if you've never run before. The key is to keep an easy pace and not skip rest days.
How many days a week should a beginner run?
Three runs per week, with rest or cross-training in between, plus one short strength session. This gives your muscles, tendons and joints the time they need to adapt and lowers your injury risk.
Do I need special shoes to start running?
You don't need anything fancy, but one well-fitted pair of running shoes makes a real difference for comfort and injury prevention. A neutral, cushioned model like the Brooks Ghost or ASICS Gel-Nimbus is a great place to start — come in store and we'll match the shoe to your stride.
Ready to run your first kilometres?
Nine weeks, three runs a week, one strength session, smart progression from the couch to 5K. The C25K plan rests on a few repeated habits: warm up before every run, cool down after, eat simply, build a little strength, and choose the right shoe. Nothing mysterious — as long as you're in good health and respect the pace.
The C25K program works because it respects the body. It doesn't promise miracles in a week: it builds a solid habit, until 30 minutes of running becomes something you do, not something you dream of doing.
