Paul Manson, a Scottish trail runner, completed a marathon each day during his Mediterranean cruise in August. Starting in Rome, he ran six marathons in ports and one on the ship. Manson, known as The Random Runner, aimed for 300 km but fell short by half a kilometer.

Manson ran each marathon in five and a half to six hours, with Rome being the slowest due to its steps and filming stops. He faced high temperatures in Naples and climbed 1,350 meters in Kotor. On the ship, he ran 185 laps of the deck to complete a marathon. Read more racing coverage.

The cruise line had doubts about Manson's challenge but allowed it to proceed. His final marathon was near Mount Etna, which was erupting, covering him in ash. Manson used the cruise as a base for exploring and running, planning to release a film on his YouTube channel. Related: Chelsea Clinton Completes Chicago Marathon in 3:47:55.
