Runner

Putting on some sneakers, stretching your legs and running for miles and miles outdoors is not (a priori) a reprehensible habit. Quite the opposite. Neither is recording race data with a smartwatch and then publish them on Stravaan app that is used to share routes, times and performance data. All this, we insist, is “a priori” because things change if the person running is a Navy officer and his publication on Strava ends up revealing the near real-time location of a nuclear-powered aircraft carrier. That is what has happened in France. Trotting on the high seas. A few days ago the newspaper reporters Le Monde they found each other with something curious: a publication on Strava that showed someone running in circles in the middle of the Mediterranean, dozens of kilometers from the coasts of Turkey and Cyprus and hundreds from the Egyptian coast. The question was obvious… What the hell was a runner doing trotting like a top in the middle of the sea? A look at Copernicus. Over the last few years Le Monde has published various items in which he warns about how Strava can be used to reveal the position of ships and bodyguards, so the reporters had their suspicions about that publication in the Mediterranean. They didn’t last long. By using the Copernicus online viewer they checked that very close to the location registered by Strava the silhouette of one of the most important ships in France, the powerful aircraft carrier Charles de Gaulle, could be seen. Click on the image to go to the tweet. What had happened? That one of the officers mobilized alongside the aircraft carrier Charles de Gaulle was better served by his runner than by the caution expected of a member of the French Navy. As reveals Le Mondethe Strava publication belongs to a young officer who on the morning of March 13, around 10:35 a.m., decided to jog around the deck of his ship. While he covered 7.23 kilometers in 35 minutes, the watch on his wrist recorded all the training data and then shared it on Strava. Once there, since their profile is public, anyone could see them. From his friends and gym colleagues to journalists in Paris. The problem is that with that small gesture he revealed the location of the Charles de Gaulle and its naval escort, which was then making its way towards the northwest of Cyprus. Something more than an oversight. We cannot know if the indiscreet runner was aboard the Charles de Gaulle or one of the ships that escorted him, but one thing is clear: his Strava account gives clues to more than just his sporting achievements. On February 14, the same officer posted another graph with data from a race off the Cotentin peninsula, also in the middle of the sea. Days later he ran in Copenhagen (probably after landing) and on March 13 he can already be located in the Mediterranean, just 100 km from the Turkish coast. A worrying snitch. It is not that the deployment of the Charles de Gaulle and the rest of the French ships was a secret. On March 3, Emmanuel Macron himself ordered publicly that they moved from the Baltic to the Mediterranean after the attack by Israel and the US on Iran and it is known that days later The aircraft carrier crossed Gibraltar escorted by the frigate Christopher Columbus. The problem is that the young officer’s publication on Strava reveals the movements of the convoy in detail and almost in real time, also revealing a worrying security breach in the Navy. Especially if you take into account that in recent weeks Iran has attacked French forces in the Middle East, leaving several wounded and one dead. “The appropriate measures”. The incident may seem more or less serious, but one thing is incontestable: Strava data allowed reporters from Le Monde accurately identify the location of the aircraft carrier and its accompanying frigate. The question that remains is… What if, instead of a newspaper, this same exercise had been done by other people with other interests? The General Staff of the Armed Forces has recognized that Strava’s publication “does not comply with current regulations” or the precautions that its staff must take at the digital level. Hence, it is proposed to adopt “appropriate measures.” But is it so worrying? Once again the problem is not only the race recorded on March 13 in the middle of the Mediterranean, but its context. This is not the first time Le Monde warns that Strava can become a breach for national security, depending on who, when and where uses it. The French newspaper has even coined the term “StravaLeaks”. Maybe it sounds excessive, but in 2025 He already warned that there were publications by French sailors that revealed the activity of nuclear submarines and months before, in November 2024, he revealed that Strava allowed thousands of Israeli soldiers to be identified. They are not isolated cases. The most dangerous oversights They were probably committed by the bodyguards of the presidents of France, the United States and Russia. By sharing their training data publicly, they left a trail that helped to partially anticipate the movements of the leaders they protected.
