1trAIner
About
1trAIner is an AI coach for running, triathlon, and other endurance sports: it builds a plan for your goal and adjusts it daily based on your watch data. The service is designed for amateurs who train on their own and want structure instead of random workouts. The first 7 days are free, then 450 ₽ per month or 4999 ₽ per year.
Who the service is for
For recreational athletes who run, swim, cycle, hike in the mountains, or combine all of these. Your level doesn't matter: plans can be built for goals ranging from your first thirty minutes of continuous running to a sub-three-hour marathon. You need a phone with Telegram; a sports watch makes the plan more accurate, but you can start without one.
The service isn't suitable if you need someone beside you during a workout: AI doesn't replace technique coaching, supervised gym training, or in-person movement analysis.
How long we've been around
Development started in May 2026, and the first working version with the Telegram coach and plans appeared at the same time. Since then, Garmin integration, a mini app, a nutrition diary and weight tracking, a mobile app for iPhone and Apple Watch, a help center, and a blog have been added.
What the coach runs on
Answers and plans are generated by the DeepSeek language model. On its own, it doesn't know your history, so the service adds context to every request: profile and goal, current plan, recent workouts with a breakdown by zones and splits, recovery metrics from your watch, nutrition diary, and constraints set in the dashboard.
On top of the model, our own rules and guidelines apply — they define what counts as acceptable training load, how to respond to low readiness, and how to build preparation in challenging conditions: heat, altitude, team sports alongside a running plan, nutrition on long runs. This is described in detail on the page "How the coach makes decisions".
Data from devices syncs automatically: Garmin — via the dashboard, Apple Watch — via the iPhone app. You can also just describe workouts in words in the chat.
What the service doesn't do
1trAIner provides informational services. It doesn't diagnose, prescribe treatment, or replace a doctor. If you have pain, an injury, or an illness, the coach directly says it's a matter for a specialist and suggests restructuring the plan rather than "toughing it out."
We don't promise results: the plan is designed for your goal, but finishing depends on how you train, sleep, and recover. For details, see the document on AI limitations and health.
