The 4-hour mark for 42.2 km corresponds to an average pace of about 5:41 per kilometre. To finish faster, you need to hold the right effort across the whole distance, accounting for time at aid stations. A 20-week build requires an existing running base and regular time for long sessions.
The coach in 1trAIner builds a plan around your level and schedule, separating endurance development from trying to run faster every time. After connecting Garmin or Apple Watch, watch data syncs automatically, and the plan is recalculated after every workout. Missed sessions and hard days change how the build continues.
Week by week, as readiness improves, long runs get longer, and nutrition is tested in advance during workouts. Progress shows up in calmer finishes to long routes and predictable recovery. Before the marathon, volume decreases: there is no need to make up missed kilometres during this period.

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 “Run a marathon (42.2 km) in under 4:00 in 20 weeks”, but moving a race, an injury, or a vacation is normal: the coach will recalculate the cycle for the new conditions.
