Thinking about running your first marathon?
Training for 42.2 km (26.2 miles) can feel overwhelming at first — but with the right plan, mindset, and gear, it’s completely achievable.
This beginner’s guide to marathon training will walk you through everything you need to know to start your journey with confidence!
Why You Should Train for a Marathon
Running a marathon is about much more than race day.
Training strengthens your mind, body, and spirit. Benefits include:
Improved cardiovascular health
Boosted mental toughness and discipline
A sense of incredible accomplishment
Community and connection with other runners
Whether you want to tick it off your bucket list or start a new lifestyle, marathon training changes you for the better.
How Long Should You Train for a Marathon?
Most beginners need between 16 to 20 weeks of structured training to prepare for a marathon.
If you’re brand-new to running, build a base first (running 3–4 times per week) for a few months before starting your official marathon plan.
Step 1: Build a Running Base
If you’re not running consistently yet, start here.
A strong base ensures you’ll avoid injuries later when training intensifies.
Base-building tips:
Start with walk/run intervals if needed.
Aim for 20–30 minutes of running 3–4 times per week.
Focus on easy, comfortable pacing.
Increase gradually — no more than 10% weekly mileage.
Step 2: Choose the Right Beginner Marathon Training Plan
Not every plan is created equal! Look for one that includes:
3–4 days of running per week
One long run that increases gradually
Cross-training days (cycling, swimming, yoga)
Rest days built into the schedule
Strength training
Step 3: Get Your Gear Ready
Running doesn’t need fancy gadgets — but the right basics make a difference.
Essentials for marathon training:
Properly fitted running shoes (get fitted at a running store)
Moisture-wicking clothing to prevent chafing
GPS watch or smartphone app to track runs (Strava)
Hydration tools (belt, handheld bottle, or vest)
Optional upgrades: foam roller, anti-chafe balm, compression socks.
Step 4: Master the Long Run
Your long run is the cornerstone of marathon training.
Each week, it grows slightly longer, building your endurance and mental strength.
Long run essentials:
Slow and steady pace (1–2 minutes slower than race pace)
Fuel every 45 minutes (gels, sports drinks, small snacks)
Hydrate early and often
Plan routes you’ll enjoy — or explore new ones!
Typically, long runs peak around 30–32 km (18–20 miles) 3–4 weeks before race day.
Step 5: Understand Easy Runs vs. Speedwork
Most marathon training runs should be easy effort — conversational pace.
You don’t need lots of speedwork as a beginner, but some training plans sprinkle in tempo runs or short intervals to build strength.
Rule of thumb:
If you can’t talk while running, you’re going too fast!
Step 6: Recovery Is Non-Negotiable
Your body gets stronger during rest — not during the run itself.
Key recovery habits:
Rest days every week
Post-run stretching or yoga
Foam rolling tight muscles
Good sleep hygiene
Nutritious meals with carbs, protein, and healthy fats
Ignoring recovery often leads to injuries like runner’s knee, shin splints, or IT band syndrome.
Step 7: Stay Mentally Tough
Marathon training is as much mental as physical.
Mindset tips for beginners:
Break the plan into weekly goals, not just the marathon
Keep a journal to celebrate small wins
Visualize crossing the finish line
Embrace tough days — they make you stronger!
