Fitness activity monitoring systems and methods

A method of tracking a pre-identified participant engaged in a fitness activity who is pre-identified by a spectator, comprising:ndetermining a location of the pre-identified participant during the fitness activity based on data received at a portable fitness device used by the pre-identified participant;determining a location of the spectator during the fitness activity based on data received at a mobile spectator device used by the spectator;determining whether the spectator is registered to track the pre-identified participant; andif the spectator is registered to track the pre-identified participant, sending a first alert to the spectator at the spectator device during the fitness activity based on the spectator location and the pre-identified participant location, wherein the first alert indicates that the pre-identified participant is within a first predetermined distance of the spectator,wherein at least one of determining the location of the pre-identified participant,determining the location of the spectator, determining whether the spectator is registered to track the pre-identified participant, and sending the first alert is performed using at least one processor.

A method of tracking a participant who is pre-identified by a spectator using a portable fitness devicenduring a fitness activity, comprising:prior to the fitness activity sending an invitation to the spectator to participate in electronically tracking the participant during the fitness activitydetermining a location of the participant during the fitness activity using the portable fitness device;determining a location of the spectator during the fitness activity using a mobile spectator device; andsending a first alert to the spectator at the spectator device during the fitness activity based on the spectator location and the participant location, wherein the first alert indicates that the participant is within a first predetermined distance of the spectator, and wherein sending the first alert occurs after a determination that an acceptance of the invitation has been received,wherein at least one of sending the invitation, determining the location of the participant, determining the location of the spectator, and sending the first alert is performed using at least one processor.

A computer program product comprising a non-transitory computer useable medium having computer program logic stored therein for causing one or more processors to track a pre-identified participant engaged in a fitness activity who is pre-identified by a spectator, the computer program logic comprising:nfirst computer readable program code for determining a location of the pre-identified participant during the fitness activity based on data received at a portable fitness device used by the pre-identified participant;second computer readable program code for determining a location of the spectator during the fitness activity based on data received at a mobile spectator device used by the spectator;third computer readable program code for determining whether the spectator is registered to track the pre-identified participant; andfourth computer readable program code for sending a first alert to the spectator at the spectator device during the fitness activity if the spectator is registered to track the pre-identified participant, wherein the first alert is based on the spectator location and the pre-identified participant location, and wherein the first alert indicates that the pre-identified participant is within a first predetermined distance of the spectator.

A method of tracking a participant engaged in a fitness activity who is pre-identified by a spectator, comprising:ndetermining a location of the participant during the fitness activity based on data received at a portable fitness device used by the participant;determining a location of the spectator during the fitness activity based on data received at a mobile spectator device used by the spectator;sending a first alert to the portable fitness device during the fitness activity based on the spectator location and the participant location, wherein the first alert indicates that the spectator is within a first predetermined distance of the participant; andsending a second alert to the spectator at the spectator device during the fitness activity based on the spectator location and the participant location, wherein the second alert indicates that the participant is within a second predetermined distance of the spectator, wherein at least one of determining the location of the participant, determining the location of the spectator, sending the first alert, and sending the second alert is performed using at least one processor, andwherein at least one of the first alert and the second alert is based on participant athletic performance data and provides a representation of the athletic performance data.

A method of tracking a participant engaged in a fitness activity who is pre-identified by a spectator, comprising:ndetermining a location of the participant during the fitness activity based on data received at a portable fitness device used by the participant, wherein the location of the participant is measured based on a position of the participant relative to a route;determining a location of the spectator during the fitness activity based on data received at a mobile spectator device used by the spectator;sending a first alert to the portable fitness device during the fitness activity based on the spectator location and the participant location, wherein the first alert indicates that the spectator is within a first predetermined distance of the participant; andsending a second alert to the spectator at the spectator device during the fitness activity based on the spectator location and the participant location, wherein the second alert indicates that the participant is within a second predetermined distance of the spectator, wherein at least one of determining the location of the participant, determining the location of the spectator, sending the first alert, and sending the second alert is performed using at least one processor.
