8-Week Base Marathon Plan "My First Marathon" is a 8-week running plan. This article combines the actual plan description with a example week from the stored workout entries.
What this plan is built for
This 8-week marathon plan is designed to support you in achieving your goal of running your first marathon. Even though it is a "beginner plan", we assume that you already have some running experience. You should have been running regularly for a while, and the length of your longest run should be around 70 minutes. Over the next 8 weeks, we will acclimatize your muscles, tendons, and ligaments to regular running. We will start with 2-3 sessions per week and primarily stay in the Base Zones. This is essential for the formation of new mitochondria and for improving fat metabolism, among other things.
Since you will be spending a lot of time in the Base Zone, you should ensure that you do not run too fast consistently, as this would miss the intended stimulus.
Additionally, it is important that you realistically assess your threshold performance (running speed). You can best orient yourself by your 10km personal best. For example, if you run about 60 minutes for 10km (equivalent to 6:00/km), then your threshold speed is approximately in the range of 6:10-6:15/km. So, a bit slower than your 10km personal best pace.
Training logic and load
The emphasis is durable base fitness, clean technique, and a rhythm you can repeat for several weeks. The important part is not upgrading easy days into hidden hard days. The workout data shows which sessions are structured and which ones are intentionally simple.
The plan contains 22 scheduled entries across 8 weeks. The sequence matters as much as the total hours: hard, technical, or long workouts only work when the surrounding days allow you to absorb them.
Example week: Week 8
This week is not a generic template. It is built from the actual training plan entries, and the workout charts use the stored workout data.
No scheduled workout in this real plan week. Use the day to absorb the load and arrive fresh for the next session.
20 min @ 75% | 8x 0 min on / 1 min easy | 15 min @ 75%
The goal is to optimize fat metabolism, train running technique, and ultimately perfect the running technique in a fatigued state with the strides.

Calm base run This run primarily serves to optimize fat metabolism. Accordingly, it should be run more relaxed than intensely.
How to read the workout charts
The chart is based on the workout data: longer segments take more width, higher intensities sit higher, and harder work is marked with stronger colors. For swim or distance-based segments, the graphic represents the planned sequence rather than GPS data.
Practical execution
What to watch
- Execute the key days precisely instead of making the easy sessions faster.
- Use the plan description as context: equipment, fueling, mobility, and realistic threshold values are part of the training.
- When life or fatigue adds pressure, trim secondary work first and keep the most important session stable.
Training effect
Executed well, the plan improves your ability to absorb the intended stimulus repeatedly. Depending on sport and phase, that means more aerobic stability, better pace durability, stronger technique under fatigue, or more confidence at target effort.
