How CoachX Works

From understanding you to designing personalized training — the complete AI coaching process

How We Understand You

Auto-Sync Your Data

When you sign up, the system automatically fetches your past week of training data. Your coach analyzes them to determine your current status.

  • Pace and heart rate across different intensity zones
  • Training habits — preferred days, weekly volume, long run distance
  • What type of running you prefer and how often you train
About Me

Tell your coach more about yourself through the About Me section for deeper personalization.

  • How long you've been running — complete beginner or returning after a break
  • Any injuries or physical limitations
  • Your goals, availability, and running preferences
Weekly Re-evaluation

Every week, the system reassesses your previous week of training to update your profile — keeping your paces, volume recommendations, and readiness always current.

Direct Feedback

If you feel the coach's prescribed paces are too fast or too slow, just tell them directly. They'll update your profile immediately and adjust future workouts.

How We Design Your Training Cycle

  • Check Your Goal
    Is it a race or a general goal? For races, the plan includes a taper phase so you arrive at race day in peak form.
  • Review Your Profile & History
    Your About Me, profile data, and past training are analyzed to plan your cycle properly — rather than starting everyone from base phase like other coaches.
  • Generate Your Unique Plan
    Based on your chosen coach's style and philosophy, a training cycle is generated that's specifically designed for where you are right now.

How We Design Each Workout

Current Phase Goal

What your training cycle is targeting this week

Your Profile

About Me, fitness level, and personal preferences

Race Goal

Target race distance, time goal, and date

Recent Training

What you've done in the past days and weeks

Recovery Status

Rest quality, sleep, HRV, and overall readiness

How We Analyze Your Training

Activity Metrics
Duration, pace, heart rate, and per-split data for each run are reviewed in detail.
Workout Completion
If the workout was created by CoachX, completion rate is analyzed — did you hit your targets?
Contextual Feedback
Combined with your goal, training phase, and overall plan, the coach provides actionable insights and suggestions.

How You Connect Your Device

CoachX supports three ways to bring your training to and from CoachX.

Sport Watch → Intervals.icu

Garmin, COROS, Polar, Suunto, Wahoo and most other sport watches connect through Intervals.icu. Activities sync into CoachX automatically and AI-generated workouts are pushed straight to the watch calendar.

  • Auto-sync of completed activities (pace, HR, splits)
  • Structured workouts pushed to your watch
  • CTL / ATL / TSB load tracking via ICU
Apple Watch → Watchletic

Apple Watch users install Watchletic from the App Store and authorize it with their CoachX account. Watchletic pulls planned workouts from CoachX and uploads completed runs back.

  • Run intervals with pace / HR / time targets
  • Completed sessions sync back to CoachX automatically
