Intervals Easily build interval workouts or choose from presets designed by coaches
Strava segments
See strava segments while route-planning. Add segments to your route and race them with real-time feedback.
Live-tracking Live location and sensor data can be shared to anyone through a URL.
Group Tracking Share location, meetup times and courses to friends on your ride.
