Couch to 5K Training Plan
Science-based 9-week program to take you from sedentary to running your first 5K
This evidence-based 9-week program uses progressive interval training to safely build your running fitness from zero. Based on the original Josh Clark program and supported by exercise physiology research, it combines run-walk intervals with gradual progression to minimize injury risk while maximizing adaptation. Perfect for complete beginners or those returning to running after a break.
How to Use This Training Plan
Getting Started
This 9-week program is designed to transform you from a complete beginner to someone who can confidently run 5 kilometers. The key to success is consistency, patience, and following the plan exactly as written—no skipping ahead, even if you feel great.
Before You Begin:
- Get medical clearance if you're over 40, have existing health conditions, or haven't exercised in over a year
- Invest in a proper pair of running shoes fitted at a specialty running store
- Choose three non-consecutive days each week for your training (e.g., Monday, Wednesday, Friday)
- Download a C25K app or use a timer to track your intervals
Understanding the Structure
Each week contains three sessions that should be spaced with at least one rest day between them. The program uses a run-walk interval method that alternates between running and walking periods, gradually increasing the running time while decreasing the walking recovery.
Session Components:
- Warm-up Walk (5 minutes): Prepares your muscles and cardiovascular system
- Run-Walk Intervals: The core workout that builds your running fitness
- Cool-down Walk (5 minutes): Helps your body recover and reduces muscle soreness
Your Weekly Schedule
Plan your training sessions around your life, not the other way around. Here's a sample weekly structure:
- Monday: Training Session
- Tuesday: Rest or cross-training (swimming, cycling, yoga)
- Wednesday: Training Session
- Thursday: Rest day
- Friday: Training Session
- Saturday & Sunday: Rest or gentle activity (walking, stretching)
Pace and Intensity Guidelines
During Running Intervals:
- Run at a "conversational pace"—you should be able to speak in short sentences
- Your breathing should be elevated but controlled
- If you're gasping for air, slow down—you're going too fast
- It's better to run too slowly than too fast
During Walking Intervals:
- Walk briskly to keep your heart rate elevated
- Don't stop completely—keep moving
- Use this time to catch your breath and prepare for the next run interval
What to Expect Each Week
Weeks 1-3: Building the Foundation
- Focus on establishing the habit and getting comfortable with the run-walk rhythm
- Expect some muscle soreness—this is normal
- Your body is learning to run efficiently
Weeks 4-6: The Challenge Phase
- This is typically the hardest part of the program
- Running intervals get longer, which can feel daunting
- Trust the process—if you've completed the previous weeks, you're ready
Weeks 7-9: Confidence Building
- You'll start to feel like a "real runner"
- The plan shifts to continuous running
- Focus on maintaining steady effort rather than speed
Common Challenges and Solutions
"I can't complete a session"
- Slow down your running pace—most beginners run too fast
- Repeat the previous week before moving forward
- There's no shame in taking extra time
"My legs feel heavy and tired"
- Ensure you're taking proper rest days
- Check your nutrition and hydration
- Consider foam rolling or gentle stretching
"I feel great—can I skip ahead?"
- No! The progressive structure exists to prevent injury
- Your cardiovascular system adapts faster than your joints and tendons
- Patience now prevents injuries later
"I miss a session or even a week"
- Simply pick up where you left off
- If you miss more than a week, go back 1-2 weeks in the program
- Don't try to "make up" missed sessions
Essential Tips for Success
Listen to Your Body
- Mild muscle soreness = normal adaptation
- Sharp pain, joint pain, or persistent discomfort = stop and rest
- If pain persists beyond 3 days, consult a healthcare professional
Fuel Your Training
- Eat a light snack 1-2 hours before running if training in the morning
- Stay hydrated throughout the day
- You don't need special sports nutrition for runs under 60 minutes
Form Basics
- Stand tall with a slight forward lean from the ankles
- Look ahead, not down
- Keep shoulders relaxed and arms at roughly 90 degrees
- Take short, quick steps rather than long strides
- Land on your midfoot, not your heels
Recovery is Training
- Rest days are when your body actually gets stronger
- Aim for 7-9 hours of sleep per night
- Consider gentle stretching or yoga on rest days
- Stay active but avoid high-impact activities
Tracking Your Progress
Keep a simple training log noting:
- Date and time of each session
- How you felt (energy level, any discomfort)
- Weather conditions
- Any notable achievements or challenges
This helps you identify patterns and celebrate your progress.

Week 9
Achievement week - running 5K
