Garmin Connect vs RUNALYZE

Garmin Connect tracks and analyzes health and fitness activities from Garmin devices through a smartphone app and website. Activity details may include time, distance, laps, elevation, pace or speed, heart rate, and route maps for GPS-tracked sessions. Depending on device capabilities, it can also display steps, stress, sleep, and other health or performance information. Training plans cover runners, cyclists, strength trainers, triathletes, and fitness enthusiasts. Users can create courses and custom workouts, and download courses to compatible devices. Optional connections include MyFitnessPal, Strava, and TrainingPeaks; those services may interpret activity data differently from Garmin Connect. Activity data is private by default, and users can adjust who can see it. Garmin says it does not sell personal data and shares activity data with third parties only when directed by the user. Most app and website features will be limited or unavailable if users do not upload personal data to Garmin. The free plan retains existing features and data. Connect+ costs $6.99 per month or $69.99 per year, with features varying by device.

RUNALYZE is a manufacturer-independent training analysis platform for endurance athletes, available on the web, Android, iOS, and through an API. It estimates effective VO2max, predicts race times from 3k to ultramarathon, and calculates acute and chronic training load from heart rate. Analysis includes trends, boxplots, dynamic histograms, summaries, data tables, and 90-day performance curves for power, heart rate, and pace. Users can optionally log sleep, HRV, resting heart rate, weight, blood pressure, glucose, temperature, illness, and injury. The service connects with Garmin, Suunto, Polar, COROS, Strava, Whoop, Oura, Wahoo, Concept2, and other services. Manual uploads accept formats including FIT, TCX, GPX, CSV, and JSON. The Android app views and analyzes account data but does not record activities. Account data is private by default. A free plan costs nothing; Supporter costs €2.50 a month; Early Premium costs €5.50 a month.
