A French officer logged a routine run on Strava, but what it revealed about a deployed aircraft carrier raised alarms

A French officer reportedly revealed the location of the aircraft carrier Charles de Gaulle after logging a routine run on the fitness app Strava. As reported by BBC News, the activity exposed sensitive operational details about a vessel deployed toward the Middle East.

The incident occurred on March 13, when the officer, identified only as Arthur, recorded a 35-minute run on the carrier’s deck using a smartwatch. The uploaded activity generated a public map that appeared to pinpoint the ship’s position.

Reports indicated the carrier was located northwest of Cyprus, about 62 miles from the Turkish coast, during heightened regional tensions. The Charles de Gaulle is the centerpiece of a French strike group operating in the eastern Mediterranean.

A fitness app once again exposed sensitive military data

The French armed forces said the reported activity did not comply with operational security rules and stated that appropriate measures would be taken if confirmed. The deployment itself is intended to protect French nationals and support allied operations in the region, amid Europe calling for calm.

The carrier hosts fighter jets, surveillance aircraft, and helicopters as part of its mission. French President Emmanuel Macron has described the military presence as defensive in nature.

This is not the first time publicly shared fitness data has exposed sensitive locations. Previous incidents have raised similar concerns, including cases involving presidential security teams and other personnel.

In earlier cases, Strava activity revealed movements tied to high-profile figures, including reports involving security details for world leaders. The platform’s public mapping features have repeatedly drawn attention for unintentionally exposing patterns.

The issue dates back years, including a 2018 controversy over Strava’s global heatmap feature. That tool visualized activity from users worldwide and revealed movement patterns at military bases, even as daily life in Iran has reflected the broader strain of the regional conflict.

Investigations later found that such data could allow observers to identify and track personnel at sensitive locations. Those concerns have persisted as the app’s user base has grown.

Strava, based in San Francisco, uses GPS data from mobile devices and fitness trackers to log exercise activity. The platform now has more than 195 million users across over 185 countries.

The scale of the app has made it a recurring point of concern in discussions about digital privacy and operational security.
