Abstract: A system and a method determine an activity of a user. Sensor data is collected from a sensor within a pod worn by the user. The sensor data is matched to a signature definition corresponding to a known activity and the sensor. When the sensor data matches the signature definition, the activity of the user is determined. Sensed data, signature data, and/or matched signature data may be communicated to and from external devices. Signatures may be learned for known activities.

Abstract: Systems and methods provide location-based athlete pacing with biofeedback. A goal pace profile based upon historical activity records of one or more athletes is determined. The goal pace profile defines a goal of a user. A mobile computing device determines a current activity of the user and compares the current activity to the goal pace profile to generate real-time status and coaching cues during the current activity.
