A method of providing gait coaching is disclosed. Run data is received and stored regarding runs of a broad and diverse population of users, as well as a more narrow set of expert users. A gait metric model is developed for determining an ideal stride length or cadence based on pace and at least one physiological characteristic. Regression coefficients for at the model are determined based on a regression of the run data from the broad and diverse population of users. In contrast, a regression constant for the model is determined based on a regression of the run data from expert users. Using the model, an ideal stride length or cadence for a particular user on a particular run can be determined and utilized to provide useful monitoring, comparison, and feedback to the user regarding his or her stride length or cadence.

Gait coaching in fitness tracking systems

The invention provides a large technological infrastructure to provide a unique comparison of athletic performance using a system. When a user traverses a route during a workout, the system can identify individual ones of a set of predetermined courses that are associated with the route. The system can include a unique point system and can compare aggregate athletic performances of different users across different geographical tracks or sections. Advantageously, people who cannot do the same course(s) can compete with one another; aggregate performances can be accumulated to give an overall performance metric; and people with differing abilities can compete with one another.

System and method for personal and peer performance ranking of outdoor activities

The invention provides a large technological infrastructure to provide a unique comparison of athletic performance using a system. The system can include a unique point system and can compare aggregate athletic performances of different users across different geographical tracks or sections (i.e., Courses). Advantageously, people who cannot do the same course(s) can compete with one another; aggregate performances can be accumulated to give an overall performance metric; and people with differing abilities can compete with one another.
