Trainer and outdoors: how to combine them

Plans

The trainer is ideal for structure and control; outdoors adds technique, endurance, enjoyment, and specificity.

Use the trainer for structured power-based sessions.
Take advantage of outdoors for long rides, technique, and real-world adaptation.
Do not try to make every outdoor workout as exact as the trainer.
Keep weekly indoor and outdoor load coherent.
If an outdoor ride was very hard, adjust the next workout.
The plan should adapt to real life, not the other way around.
