In certain embodiments, real-time playback modification for activity event playback may be facilitated. In some embodiments, an event list portion and an event playback portion may be provided on a user interface, where the event playback portion is configured to present a playback of events on a location map in accordance with event detection times and a set of event layers for the event playback. While the event playback is occurring, a user selection of events may be obtained via the event list portion of the user interface. While the event playback is occurring, a set of layers for the event playback may be modified based on the user selection. In some embodiments, based on the modification to the set of layers, event layers may be overlaid onto the location map of the event playback portion of the user interface.
