The Region of Thessaly, the Naval Sports Association of Larissa (NEL), the Municipality of Agia, the Cultural Association of Velikas "Filoktitis" and the Café Spitaki co-organized the 12th Panhellenic Marathon Swimming Camp "Filoktitis".

The race was held on Sunday September 3rd, 2017 and included two parallel 10 and 5 km long runs. The start of the ten kilometer race was settled at the harbor of Agiokambos at 11 a.m. while the  5 kilometers race began from the beach of Kato Sotiritsa at 1 p.m. . The end of both runs was at the beach of Velika on the organized coast, in front of the Café Spitaki.

"Filoktitis" has been a major athletic event for the past twelve years and a unique reference point for the region since it is the only one - of its kind - offshore race to be held in the prefecture of Larissa. The participation of swimming athletes from Larissa, Thessaloniki, Athens, Halkidiki, Skiathos and other regions of Greece with ages ranging from 14 to 67 years is a key feature of the race!

Health promoter of the match was EPOMEA Larissa, as well as the newly established Larissa Diving Club.
