12 Weeks 10km PB Plan Professional is a 12-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 12-week PB plan is designed to lead you to a new personal best over 10km. The number of runs and the total mileage are clearly aimed at runners who already have some "running experience", meaning they have accumulated a few kilometers.
It is important that you realistically assess your threshold performance. If you run the half marathon in the range of 80-90 minutes, then this is slightly faster than this pace (1:20 HM corresponds to 3:45/km - then your threshold speed is around 3:38-3:40/km). If you run slower, you should rather orient yourself towards your 10km personal best. Here, the threshold pace is somewhat slower (50 minutes over 10km corresponds to 5:00/km - then your threshold speed is more in the range of 5:05-5:10/km).
A realistic assessment ensures that you complete the base runs at a calm pace (primarily in the area of fat oxidation) and that you run the fast sessions and intervals realistically below or slightly above your threshold. This is important so that you can consistently maintain the volumes and sessions. This is the most important thing - consistency! This should also be the goal for the intervals. They should be executed in the specified times from the first to the last interval as planned.
Training logic and load
In the peak phase precision matters: key sessions count, but freshness and clean execution decide the outcome. 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 84 scheduled entries across 12 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 5
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.
Yoga for Runners - Today I have brought you a short, soothing post-run session. The session is designed to help you release tension from your body - especially from the muscles primarily involved in running.
50 min @ 80% | 8x 0 min on / 1 min easy
The goal is to optimize fat metabolism and to perfect running technique in a fatigued state at the end with the strides.
15 min @ 80% | 1x 4 min on / 2 min easy | 1x 4 min on / 2 min easy | 1x 3 min on / 2 min easy + 4 more steps
The goal of this session is to improve your sub-distance performance and enhance your performance above the anaerobic threshold.
15 min @ 80% | 20 min @ 90% | 15 min @ 75%
The goal of the tempo run is to develop pace endurance. After a relaxed warm-up, the focus is on maintaining a high speed with clean technique until the end.
Perform a 30-minute athletic / stability training session. Typical exercises may include: - Lunges - Squats - Superman - Push-ups - Leg raises - Plank - Side plank - etc.
15 min @ 80% | 5x 1 min on / 2 min easy | 5 min @ 70% | 5x 1 min on / 2 min easy + 1 more step
The goal of the hill runs is to improve your sub-distance performance and enhance anaerobic capacity.
1:40 h @ 75%
Easy base run This run primarily serves to optimize fat metabolism. Accordingly, the pace should be more relaxed than intense.
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.
