Strava activity log for a 7.23km run by Arthur, recorded 13 March 2026 in the Mediterranean Sea off Cyprus. Activity stats: 7.23 km distance, 35:58 duration, 4:58 /km pace, 2m total elevation gain, 535 calories, recorded with Garmin Forerunner 955.

This image is a screenshot of a public Strava fitness activity that went viral as an accidental security leak. The activity is a foot run logged by a French sailor named Arthur, dated 13 March 2026, created when he ran laps on the deck of a French nuclear warship that was on a stealth deployment to the Middle East, operating with its transponder turned off to hide its location. The Strava activity plots the 7.23km run directly on the open Mediterranean Sea near Cyprus, revealing the warship's exact secret position. Activity stats confirm the run only has 2 meters of elevation gain, consistent with running on the flat deck of a moving ship.

This viral image and story originated from the 9GAG platform, based on an incident where a French nuclear warship was traveling to the Middle East in stealth mode to keep its location hidden, but a sailor on board accidentally leaked the vessel's exact position by tracking his daily on-deck run with Strava, a popular fitness app that shares activity locations publicly by default.
