Preparation for your first 21.1 km is designed for 16 weeks and does not set a mandatory finish time. For such a horizon, an already established habit of running is useful; with a small initial base, the timeline may need to be revised. The main tasks are to gradually get used to prolonged effort and to sort out nutrition on the distance in advance.
The coach in 1trAIner takes into account your level, schedule, and available time for a long run. After connecting Garmin or Apple Watch, data arrives automatically, and the plan is recalculated after every workout. If the new distances feel hard, the next step is adjusted based on the training load you completed.
As you adapt, long runs take more time, while easy sessions help you stay consistent without extra intensity. During workouts you test the gear, fluids, and nutrition you plan to use on race day. Progress shows in your ability to finish longer outings calmly and recover afterward.

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 the half marathon distance (21.1 km) in 16 weeks of preparation”, but moving a race, an injury, or a vacation is normal: the coach will recalculate the cycle for the new conditions.
