Yigri

Yigri is a running-analysis service that helps athletes understand their training and whether it is working. It connects planned workouts and completed runs, including Strava activity data, to organize training, assess performance, and surface useful trends. Runners can import a coach’s calendar, view workouts in the context of their week, and get suggested running windows based on weather conditions.

Yigri compares each run with an individual baseline rather than relying on totals alone. Its Run Pulse explains whether an effort was below, near, or above expectations, with context such as pace, heart rate, weather, and footwear. Weekly readouts bring together easy-run efficiency, race-speed fitness, workout execution, pacing, and endurance signals to show what changed and what may need attention next. The service also helps runners see how different shoes perform for them and offers recommendations for upcoming sessions. Yigri is available through the App Store and is free to start, with account setup described as taking about two minutes and requiring no credit card.
