Abstract: 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.

Abstract: A system for gait analysis may include a mobile data recording device configured to record accelerations associated with user motion and a data processing device in communication with the mobile data recording device. The data processing device can be configured to receive acceleration data from the mobile data recording device and process the acceleration data to extract stride data sequences from the acceleration data through use of bounding boxes on one or more points of the acceleration data. Each of the stride data sequences comprising data for a corresponding stride. The bounding boxes may define time and acceleration bounds. The data processing system may further determine one or more stride metrics. According to one embodiment, the data recording device may be a smartphone or other device having an accelerometer with a limited range that is inadequate to capture the full range of accelerations experienced by a runner.
