12 Week To Fitness: A Beginner's 10k Training Plan
Preparing for your first 10K is an achievable goal with the right structure, pacing, and gear. This 12-week training plan balances gradual endurance building with injury prevention, using a Rate of Perceived Exertion (RPE) system to personalise intensity.
First Things First
It is worth noting that training should be a challenge, even for regular runners. However, no training should be so challenging that it drains you of every last ounce of energy, and neither should it just be about long runs.
Above all, your training should be fun, so with that in mind, we’ve kept all the technical jargon to a minimum, but to get the most out of the plan, you will need to understand how to gauge your rate of perceived exertion (RPE).
Top Tip → Ensure you have comfortable, well-fitting running shoes and are wearing the right clothing for running. Remember, if you're not feeling comfortable, you're not going to want to keep going!
Building Endurance Safely
The plan prioritises low-impact progression, alternating jogging intervals with walking recovery. Weeks 1–4 focus on establishing a routine with 2–4K distances at RPE 4–5 (steady jogging pace), while Weeks 5–8 introduce tempo runs (RPE 6–7) and longer 5–7K sessions. The final month (Weeks 9–12) incorporates speed intervals (RPE 7–8) and 7–8K endurance runs, peaking with a 10K race day.
How Fast Should I Be Running?
This is one of the most common questions runners ask when training for an event. The trouble is, how do you define “fast?”
A fast pace for one person may well be a slow pace for another. This is where RPE comes in. RPE lets people define their own pace by gauging how hard they feel they are working.
Rate of Perceived Exertion (RPE) Explained
RPE tailors intensity to individual fitness levels, avoiding one-size-fits-all pacing. The scale ranges from 0 (rest) to 10 (sprint), with targets for each workout type:
- Easy runs → RPE 4–5 (conversational pace)
- Tempo efforts → RPE 6–7 (sustainable but challenging)
- Speed intervals → RPE 7–8 (near-maximum effort)
How To Measure Rate of Perceived Exertion (RPE | Effort Level)
- Sitting Down/Chilling
- Sunday Stroll
- A Brisk Walk
- A Very Gentle Jog
- A Steady Jogging Pace
- Tempo Pace/A Quick Jog
- A Quick But Sustainable Pace
- Tough Going/You're Pushing Yourself
- Running Away From Zombies
- Usain Bolt Level Pace
12-Week Training Plan Breakdown
Weeks 1–4: Foundation Phase
- Goal → Adapt to regular movement
- Key workouts → 1K jog/walk repeats (2 sets), 5min jog intervals
- Sunday runs → Gradually increase from 2K to 4K
Weeks 5–8: Building Phase
- Goal → Introduce sustained efforts
- Key workouts → 1K jog/walk repeats (3 sets), 5min tempo runs
- Sunday runs → Progress to 5–7K
Weeks 9–12: Peak Phase
- Goal → Enhance speed and endurance
- Key workouts → 1K repeats at RPE 6–7, 3min high-intensity intervals
- Sunday runs → 7–8K distances, tapering to 2–3K pre-race
Nutrition and Hydration Tips
- Pre-run → Eat a banana or toast with peanut butter 1–2hrs beforehand
- During runs → Sip water every 15–20min; for >60min efforts, use electrolyte tablets
- Recovery → Consume protein (e.g., Greek yoghurt) within 30min post-run
Final Race Day Preparation
- Week 12 → Reduce mileage by 30% to freshen legs
- Night before → Carb-load with pasta or rice, and lay out gear
- Morning of → Eat a light breakfast, arrive early, and stick to your proven pacing strategy

FAQs
A 10K training plan is a structured programme designed to prepare you for running a 10K race. It includes a mix of running workouts, strength exercises, and recovery sessions to help improve your endurance, speed, running form, and overall fitness. Following a plan helps you achieve your race goals and avoid injuries.
Most 10K training plans last between 8 to 12 weeks, depending on your current fitness level and experience. This gradual progression allows your body to adapt and reduces the risk of injury.
The plan includes 3–4 weekly sessions (walking, jogging, tempo runs) with rest days to minimise injury risk. Consistency matters more than daily mileage.
Prioritise the Sunday long run—if time-crunched, shorten mid-week sessions rather than skipping entirely. Flexibility prevents burnout.
- Warm up with dynamic stretches (leg swings, lunges)
- Stick to RPE guidelines to avoid overexertion
- Replace shoes every 500–800km
Aim for 60–75 minutes initially. Pace improves with consistent training—focus on finishing before targeting speed.
Absolutely. Many events allow participants to walk the 10K. If you plan to walk the whole distance, you’ll still have plenty of time to finish within the event’s time limits.
Before running, choose a light meal or snack with carbohydrates and some protein. After running, focus on recovery foods that include protein and carbohydrates to help muscle repair and replenish energy stores.
Yes, treadmill training can be effective for a 10K, especially for speed and tempo workouts. Just make sure to include some outdoor runs to get used to race conditions.
