A marathon training plan with a treadmill for beginners
When it comes to fitness challenges, preparing for a marathon is a high point for many runners. For beginners, DeerRun treadmills offer a controlled environment to build endurance and prepare adequately. This guide outlines a structured marathon treadmill training plan specifically designed for beginners.
Understanding the basics of marathon training
Before delving into the specifics of treadmill training, it's important to understand the basic principles of marathon preparation. This section covers topics such as setting realistic goals, understanding the physical demands of a marathon, and the importance of gradual progression in training.
Benefits of treadmill training for marathon preparation
Training on a treadmill offers unique benefits, especially for beginners. This section explores the advantages of treadmill training, including controlled conditions, adjustable speed and incline, and the ability to simulate race scenarios. It also opens the door to focused core training using a treadmill for abdominal routines, which helps improve stability and running efficiency.
Structure your treadmill marathon training plan
This section provides a detailed week-by-week breakdown of the training plan, covering key aspects such as:
Weeks 1–4: Building your foundation
Start with 3-4 days of treadmill running per week, alternating between short runs (20-30 minutes) and one weekly long run (5-8 km or more). Set the treadmill incline to 1% to mimic outdoor resistance and reduce joint stress. Focus on building endurance at a conversational pace—this will be your aerobic foundation.
Weeks 5–8: Increase mileage
Gradually increase your long run distance by 1-2 kilometers per week. Aim for 12-15 km by week 8. Incorporate gentle hill walks or incline jogging to activate your core running muscles and improve cardiovascular capacity.
Weeks 9–12: Sharpening speed and endurance
Introduce faster segments or tempo runs once a week. Add a second weekly long run if time allows. Treadmill features like interval mode or heart rate monitoring can help you stay within your target training zones.
Nutrition tips for marathon training
Proper nutrition is key to supporting your training efforts. This section outlines nutritional guidelines tailored to marathon runners, including pre-workout meals, hydration strategies, and post-workout recovery nutrition.
Common challenges and how to overcome them

The best treadmill workouts for marathon training
Train smartly in the hall and achieve your racing goals
Treadmill running isn't just a winter fix—it's a powerful tool for consistent and controlled marathon training. Whether you're chasing a new personal best or preparing for your first 26.2 miles, the right treadmill workout can help you improve endurance, pace, and mental grit.
Why train for a marathon on a treadmill?
Running indoors may seem monotonous, but it has great benefits:
● Consistent pace control: Perfect for pacing your long runs and speed workouts.
● Weatherproof training: No wind, rain or freezing temperatures to interrupt your rhythm.
● Custom gradient options: Simulate hilly courses or mimic outdoor terrain.
● Safe, gentle surface: Gentler on the joints than concrete.
Even compact devices like the DeerRun A1 Pro prove that serious training can take place right in your living room – just ask runners preparing for major events like the London Marathon, where indoor running performance plays a crucial role in staying race-ready.
The DeerRun A1 Pro 's high-performance treadmill packs plenty of power into a sleek, foldable design perfect for small spaces. It features a high-speed motor, intelligent shock absorption, smart app compatibility, and a wide running belt—ideal for runners who want to exercise without the bulk of a gym machine.
The DeerRun A5 Pro also supports a convenient and effective home workout program. With its space-saving, foldable design, smooth operation, and intuitive controls, it's a solid choice for regular running, warm-up, or walking. It offers excellent value for those seeking simplicity and convenience.
Real users like Louis and Emily have already put both the DeerRun A1 Pro and the DeerRun A5 Pro to the test, using them as essential tools in marathon preparation. Whether it's pre-race warm-ups or consistent indoor mileage, these treadmills prove that elite training can start in your living room.
The best treadmill workouts for marathon training
1. Treadmill with long run
Long runs are non-negotiable in marathon preparation. On the treadmill:
● Duration: 60 to 150 minutes
• Pace: Keep it 60–90 seconds slower than your marathon pace
● Pro tip: Break it down into mental chunks (e.g. 3 x 5-mile segments)
Why it works: You build endurance while staying mentally strong. It's a great way to simulate fatigue without distractions.
2. Treadmill tempo training
Tempo runs improve your lactate threshold and help you maintain marathon pace for longer.
● Warm-up: 10–15 minutes of easy jogging
● Main set: 20–40 minutes at your target marathon pace or slightly faster
● Cooling down: 10 minutes of light jogging
This is a must in any solid treadmill running plan.
3. Treadmill speed workouts (intervals)
Increase your speed and VO2max with interval sessions:
● Example: 6 x 800 m (0.5 miles) at 5 km pace
● Recovery: 400 m (0.25 miles) easy jogging between efforts
● Incline: 1% to mimic outdoor resistance
These sessions are ideal if you are short on time but want to achieve maximum impact.
4. Hill repetitions on the treadmill
Simulate hills on race day or simply build stronger running muscles.
• Training: 8 x 60 seconds at 5–7% incline, moderate pace
● Recovery: 90 seconds at 0–1% incline, easy pace
Even if your marathon is flat, hill training increases strength and endurance.
