5. The computer-implemented method of claim 1 , wherein the coaching information provided to the user is specific to at least one of the one or more determined events.

6. The computer-implemented method of claim 1 , wherein the coaching information is generated based, at least in part, on data associated with weather and terrain at a location of performance of the athletic activity.

7. The computer-implemented method of claim 1 , wherein at least one sensor of the one or more sensing devices is arranged in an article of footwear of the user.

8. One or more non-transitory computer readable media storing computer readable instructions that, when executed, cause at least one computing device to:

determine a type of physical activity associated with an athletic activity performed by a user;

based on the determined type of physical activity performed by the user, identify a plurality of activity templates associated with the physical activity;

receive raw sensor data associated with the athletic activity performed by the user, the raw sensor data being received from one or more sensing devices;

determine, based on a signature of a signal received from the one or more sensing devices, a category of athletic activity being performed;

analyze the received raw sensor data to determine one or more events performed during the athletic activity of the user;

select a plurality of athletic activity templates for comparison, the plurality of athletic activity templates being selected based on the determined category of athletic activity being performed;

compare the determined one or more events to the selected plurality of activity templates;

determine whether the determined or more events match one or more activity templates of the selected plurality of activity templates;

responsive to determining that the determined one or more events match one or more activity templates, classify the events as performance of a first action of a first type;

determine a quality of the first action, wherein determining the quality of the first action further includes instructions that, when executed, cause the computing device to:

identify one or more optional events associated with the one or more matching activity templates;

determine whether a match exists between the one or more optional events associated with the one or more matching activity templates and the determined one or more events;

determine whether the quality of the first action is below a predetermined threshold; and

responsive to determining that the quality of the first action is below the predetermined threshold, provide coaching information to the user; and

responsive to determining that the determined one or more events do not match one or more activity templates, storing the received sensor data.

9. The one or more non-transitory computer-readable media of claim 8 , wherein determining the quality of the first action further includes instructions that, when executed, cause the computing device to:

determine a strength of a match between the determined one or more events and the one or more activity templates.

10. The one or more non-transitory computer-readable media of claim 8 , wherein providing coaching information to the user further includes instructions that, when executed, cause the computing device to:

provide recommendations for improving the quality of the first type of action.

11. The one or more non-transitory computer-readable media of claim 8 , wherein the coaching information provided to the user is specific to at least one of the one or more determined events.

12. The one or more non-transitory computer-readable media of claim 8 , wherein at least one sensor of the one or more sensing devices is arranged in an article of footwear of the user.

13. A system comprising:

a sensor system including a plurality of sensors, the sensor system further including:

a first processor; and

memory storing computer readable instructions that, when executed, cause the first processor to:

receive raw sensor data associated with athletic activity of a user;

determine, based on a signature of a signal received from the plurality of sensors, a category of athletic activity being performed; and

transmit, to an activity processing system, the determined category of athletic activity being performed and the raw sensor data; and

the activity processing system, including:

a second processor; and

memory storing computer-readable instructions that, when executed, cause the second processor to:

receive the transmitted determined category of athletic activity being performed;
