What this plan is built for

This training plan focuses on the proper return to training after a short illness such as a cold, stomach upset, etc. If you have been sick or injured for more than a week, you will need to adjust your training for longer than just one week. This should definitely be done in consultation with a doctor and/or physiotherapist to rule out any potential long-term effects. This week is really just about getting back into your training routine after a short break.

In general, you should always take an additional day off if you feel ready to start training again. Additionally, in the coming days, you should place even more emphasis on healthy nutrition and sufficient sleep than you normally would. Sleep and good nutrition are the most important factors for a well-functioning immune system. Furthermore, in the first days of your return, you should increase your intake of electrolytes and micronutrients, as illnesses are often associated with deficiencies.

The first training sessions usually feel quite bumpy - don’t let that discourage you. The good feeling comes back quickly, and often you will find yourself much fitter after the return week than you feared. So approach it with a certain calmness: In tranquility lies strength!!!

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 7 scheduled entries across 1 week. 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 1

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.

If the weather is nice, you ride outside - preferably gravel or MTB. If you train indoors, 90 minutes of LIT is sufficient.

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.
