1. A system for monitoring an athletic performance, comprising:

  • an input system for;

    receiving right foot launch input data from a right foot sensor system relating to a plurality of right foot launch events, wherein the right foot launch input data includes at least a timestamp associated with each right foot launch event indicating a time that respective right foot launch event occurred;

    receiving left foot launch input data from a left foot sensor system relating to a plurality of left foot launch events, wherein the left foot launch input data includes at least a timestamp associated with each left foot launch event indicating a time that respective left foot launch event occurred;

    receiving right foot strike input data from the right foot sensor system relating to a plurality of right foot strike events, wherein the right foot strike input data includes at least a timestamp associated with each right foot strike event indicating a time that respective right foot strike event occurred; and

    receiving left foot strike input data from the left foot sensor system relating to a plurality of left foot strike events, wherein the left foot strike input data includes at least a timestamp associated with each left foot strike event indicating a time that respective left foot strike event occurred; and

    a processor system programmed and adapted to;

    define a first set of disqualifying events;

    discard, based on the first set of disqualifying events and at least one of the received launch events, one or more portions of the right foot launch, left foot launch, right foot strike, or left foot strike input data, resulting in filtered input data; and

    identify, based on the filtered input data, a first set of timestamps, wherein the first set of timestamps includes temporally adjacent right foot launch, left foot launch, right foot strike, and left foot strike events;

    determine if at least timestamp information associated with the first set of timestamps corresponds to one or more templates, of a predetermined set of templates, the templates corresponding to different types of activity;

    determine that a first template is associated with at least the timestamp information based on one or more other athletic activity events detected within a predetermined temporal proximity to the timestamp information; and

    determine a first flight time associated with the first set of timestamps based on the first template, wherein the first flight time is based at least in part on a first time duration included by the first set of timestamps when both the left foot and the right foot are simultaneously not in contact with a surface; and

    an output system that outputs output data including information containing or derived from the first flight time.
