Systems, methods, and apparatuses for detecting the start of a walk event are disclosed. The method comprises detecting that a wearable device is in a walk mode if it is determined that the wearable device has exited a geo-fence zone and that the wearable device is not connected to a wireless network; comparing current environment details associated with the wearable device to past walk environment details associated with the wearable device to identify at least one similarity between the current environment details and the past walk environment details; confirming that the wearable device is in the walk mode upon identifying at least one similarity between the current environment details and the past walk environment details, the predictive function refined using the one or more previous responses to a walk mode prompt; and transmitting a recorded GPS location of the wearable device while the wearable device is in a walk mode.
