The benchmark for this programme is to ski 42.2 km after 20 weeks of preparation, with no target finish time. For such a distance, not only overall volume matters, but also the ability to keep moving with controlled effort and to eat and drink on time. The starting load depends on your base: the preparation period itself does not mean the distance is already within your reach.
The 1trAIner coach builds the plan around your current endurance and schedule, setting aside time for long sessions separately. Data from your Garmin/Apple Watch syncs automatically, and the plan is recalculated after every workout. Your comments on nutrition, fatigue and trail conditions help refine the load: speed on snow cannot be assessed in isolation from the conditions.
The first weeks are needed to assess how well you tolerate the load, then, with sufficient recovery, the share of long work grows. In such sessions you test nutrition, drinking, equipment and your ability not to start too fast. Closer to the race, volume decreases so you arrive at the distance without excess fatigue. A sign of progress is more even effort in long workouts, not a speed record in each of them.

Frequently asked questions
Do I need a sports watch?
No. You can start without one: the plan is built from your answers about your goal, level, and available time. With a Garmin or Apple Watch, accuracy is higher — the coach sees your heart rate, sleep, and actual weekly volume.
What happens after the free week?
The subscription costs 450 ₽ per month or 4999 ₽ per year. There are no automatic charges: your card is not saved, and renewal is only manual via the link in the reminder.
Is the coach a person or a program?
1trAIner is an informational service: plans and reviews are prepared by AI based on your data. This is not a medical service and not a substitute for a doctor or an in-person coach.
What if my goal changes?
Let us know in the chat. Right now the plan is built for the goal “Complete a marathon distance (42.2 km) in 20 weeks of preparation”, but moving a race, an injury, or a vacation is normal: the coach will recalculate the cycle for the new conditions.
