Flow measures how well a rider maintains speed during a ride or sections of their ride. It takes into account factors such as your speed consistency throughout your ride, fluidity through turns and other factors. Your Garmin device continuously calculates Flow during your ride. After the ride, when you sync, you’ll receive a chart of your Flow scores throughout the ride and an overall average Flow score for the ride, which you can view in Garmin Connect.
Lower Flow scores indicate an overall smoother ride. Higher scores represent a ride with more speed fluctuations or stops. Flow is a useful metric for analyzing your ride performance on a trail. For example, you can compare Flow scores between two rides on the same trail to look for areas of improvement or decline in how smoothly you were riding.
