United States soldiers mapping their runs through fitness devices have accidentally revealed sensitive military information.

An interactive map posted by GPS tracking company Strava uses satellite data to show the location and movements of its 27 million users over the past two years.

Those users include the owners of fitness devices such as Fitbit, Jawbone, and Vitofit.

While the map is densely populated in the United States and Europe, desert countries and warzones are sparser.

Zooming in on known military bases in Iraq and Syria reveals hives of tracked activity, presumably mapping the fitness and patrol routines of soldiers.

The issue lies when the activity maps show up in unknown and potentially sensitive sites, presumably because the soldiers stationed to these locations are using their fitness devices.

US Central Command spokesperson Air Force Col John Thomas said the military is looking into the map's repercussions, the Washington Post reported.

In 2013, the Pentagon distributed 2500 Fitbits among military personnel in an effort to combat obesity.

The map was posted online in November but the sensitive information was only publicised on Sunday after a 20-year-old international security and Middle East studies student from Australia zoomed into military bases.

While the map doesn't identify users, it details extensive information on the whereabouts and routines of soldiers and other military personnel.
