Intervals.icu AI Analysis: Turn Fitness, Fatigue, and Activity History Into a Training Plan

Intervals.icu is already strong at showing fitness, fatigue, form, training load, and completed activity history. The next step is turning that information into a plan you can actually follow. TrainingDojo uses Intervals.icu AI analysis inside Coach Dojo so an AI cycling coach or AI running coach can start from your recent workload instead of a blank prompt.

Coach Dojo reads roughly the last 90 days of Intervals.icu history, summarizes what you have been doing, asks the subjective questions your data cannot answer, and generates a cycling, running, or triathlon plan you can import, structure, or refine.

What TrainingDojo Reads From Intervals.icu

• Completed activities in the selected recent history window
• Sport type, title, local date, duration, distance, and description
• Training load, intensity, average power, and heart-rate metrics when available
• Wellness records for CTL, ATL, and Form when Intervals.icu provides them
• A fallback performance trend estimated from activity load when wellness records are unavailable

That creates the baseline a generic AI prompt is missing. Instead of asking "make me a cycling plan" and hoping the first week fits, Coach Dojo can see whether your recent training looked like three short rides, a steady run block, a mixed triathlon week, or a high-load build that needs recovery.

How Intervals.icu AI Analysis Becomes a Plan

1. Open Coach Dojo and choose Intervals.icu as the history source.
2. Use a saved encrypted Intervals.icu connection or enter manual API credentials inline.
3. Coach Dojo analyzes recent completed activities and performance trends.
4. You answer the goal, schedule, fatigue, travel, and constraint questions data cannot know.
5. TrainingDojo generates an import-friendly plan that can move into the rest of the workflow.

The finished plan is not trapped in chat. You can use the CSV importer to send it to Intervals.icu, use the structured workout builder for key sessions, or review Pro options on pricing.

Why This Matters for AI Cycling and Running Coaching

The most common failure mode for an AI cycling coach or AI running coach is scale. It can write a reasonable workout progression, but it does not know whether your current body is ready for it. Intervals.icu history helps answer that. Recent volume, long-session durability, load, and fatigue trends keep the plan closer to what you can actually absorb.

For cyclists, that can mean building FTP, threshold, sweet spot, or endurance blocks from recent ride load. For runners, it can mean fitting workouts around current mileage and long-run durability. For triathletes, it helps balance swim, bike, run, and strength patterns instead of overloading the week.

How This Fits With Other TrainingDojo Workflows

Intervals.icu AI analysis is for deciding what should happen next. Workout Vault is for reusing what already worked. If you want to mine completed activities and rebuild the best sessions as templates, read how to export Intervals.icu activities into Workout Vault.
