So, you signed up for a 5K… and now you have only four weeks to prepare? Don’t stress! Whether you’re new to running or getting back into it, a month is definitely enough time to build endurance and cross that finish line feeling strong.
This 4-week 5K training plan is designed for beginners and casual runners who want a structured approach to training for a race with limited time.

Week 1: Build a Base
The first week is all about getting comfortable running at a steady pace. If you’re new to running, focus on run-walk intervals—jog for 1-2 minutes, then walk for 1-2 minutes.
schedule:
- Day 1: Run/walk for 20-25 minutes
- Day 2: Cross-train (cycling, yoga, or strength training)
- Day 3: Run/walk for 25 minutes
- Day 4: Rest or light yoga
- Day 5: Run/walk for 25-30 minutes
- Day 6: Cross-train or brisk walk for 30 minutes
- Day 7: Rest
Week 2: Increase Endurance
This week, you’ll start running for longer periods before walking. Aim for a 3:1 run-to-walk ratio.
schedule:
- Day 1: Run/walk for 25-30 minutes
- Day 2: Strength training or low-impact cross-training
- Day 3: Run/walk for 30 minutes
- Day 4: Rest
- Day 5: Run/walk for 30-35 minutes
- Day 6: Cross-train or brisk walk
- Day 7: Rest
Week 3: Improve Speed & Stamina
Time to push the pace a little! Introduce some short, fast intervals to build endurance and speed.
Schedule:
- Day 1: Run/walk for 30-35 minutes with short bursts of faster running
- Day 2: Strength training or yoga
- Day 3: Run 2 miles at a steady pace
- Day 4: Rest
- Day 5: Run 2.5 miles at race pace
- Day 6: Easy walk or cross-train
- Day 7: Rest
Week 4: Race Prep
Tapering (reducing intensity) will help your body recover before race day. Focus on shorter, controlled runs, and trust your training!
schedule:
- Day 1: Run 2 miles at an easy pace
- Day 2: Strength training or yoga
- Day 3: Run 1.5 miles with a few faster bursts
- Day 4: Rest
- Day 5: Run 1 mile at race pace
- Day 6: Rest or short walk
- Day 7: RACE DAY!
Race Day Tips
- Start conservatively: If you take nothing else from this article, remember to START SLOW. There’s a tendency to start out too fast because you’re excited and your adrenaline is pumping but trust me, don’t do it. Start at a conservative pace at least for the first mile, settle in, and then you can increase your speed gradually from there. You’ll feel SO much better at the end of the race if you use this approach!
- Stay hydrated: Drink water before and during the race to be sure you don’t get dehydrated. This is especially true for hot summer races. Also, make sure you stay hydrated throughout the month of training – this will help with recovery.
- Have fun! You put in the work, so now it’s time to enjoy it. Take it all in and cross that finish line with a smile!
