β Garmin Connect Integration
Unlock the full potential of your Garmin data with AI-powered insights
Run Diary transforms your Garmin wearable data into actionable training intelligence. While Garmin Connect excels at recording detailed fitness metrics, many runners struggle to interpret this data and answer the crucial question: "What should I do next?"
Run Diary bridges this gap by applying AI analysis to your Garmin data, providing personalized coaching that adapts to your current fitness stateβnot just historical race results.

Unlike traditional VDOT calculations based on race results, Run Diary continuously recalibrates your pace zones using the last 30 days of Garmin data, ensuring accuracy even months after your last race.
Race Pacing Strategy
Predicts realistic finish times from your training data and generates 5km split strategies. Provides pace adjustment advice based on weather forecasts (temperature, humidity).
Context-Aware AI Chat
Unlike generic AI chatbots, Run Diary dynamically references your Garmin data based on your questions. Ask about weekly plans, fatigue levels, or injury concernsβAI retrieves only relevant data for personalized responses.
