SEGAS was an innovator yet again as, following communication with the Olympic Committee, it organised the International Classical Marathon Race. Despite the fact that the first event was held in 1955, the idea had its roots as far back as 1938, when the IAAF gave SEGAS the authority to take the necessary steps to realise this plan. The first race, planned for the first fortnight in 1939, had to be postponed because of WW II.

The reputation of the Classical Marathon spread beyond Greece's borders very quickly. The best runners have honoured the event which takes place every two years with their participation. Among the athletes that have taken part were the legendary two-time Olympic gold medallist, Abebe Bikila, Olympic gold medallist Mamo Wolde, and famous runners such as Adcox, Kimihara, Aktsan. Indicative of the success of this event is the fact that the number of athletes taking part doubled in the second meet.

The distance of the race was 42,195 metres, starting at the monument in Marathon and finishing in the Panathinaikos Stadium. According to IOC rules, participation is open to all athletes who are certified by the athletic federation of their country.

The name of the winner is inscribed on a cup that remains at the offices of SEGAS. The athlete receives a copy of the cup as well as an olive wreath. Those placed second and third receive cups from SEGAS.

It is understood, however, that mere participation in such a race where the athlete's will, courage and perseverance are put to the test, is of itself a distinction. Runners of marathons undoubtedly run to win, but their first concern is to achieve a time that is better than their last. Finishing such a long race presupposes that the athletes will surpass themselves and will exhaust their reserves of will and faith.
