Running is already mentioned by Homer among the sports practised by the youth of Phaeacia; it was very popular, too, in after times, and formed an important part of the gymnastic contests which took place at the great Hellenic festivals. Speed was not of as much importance as endurance, and overcoming difficulties of ground; for they did not run on firm earth, but in soft sand, where it was doubly difficult to run fast, since the feet sank in if they were too firmly set down. There were four kinds of racing, according to the length of the course: the single course ([Greek: stadion]), the double course ([Greek: diaulos]), the horse race ([Greek: hippios dromos]), and the long course ([Greek: dolichos]). The single course was the length of the race-course, or _stadium_--that is, six hundred feet; the runner had to measure the course from beginning to end. In the double course the same space was passed over in both directions--that is, twice. In the horse race they ran twice backwards and forwards, consequently four _stadia_, which therefore was the length of the course on horseback, and hence its name. There are very different accounts about the length of the long course; seven, twelve, twenty, and even twenty-four _stadia_ have been mentioned; the last (about three miles) seems to have been the usual length at Olympia. It is impossible to say whether these various statements are due to erroneous calculations or differing customs; still there is no reason to doubt even the longest course mentioned, since many of our modern runners can achieve far greater distances, so that a course of twenty-four _stadia_ might very well have been required as the highest achievement of a good athlete. Our authorities, however, do not inform us what degree of speed was usual. We know that the educational and practical value of running depended not only on the attainment of great speed over a short distance, but also on the endurance necessary for achieving a long distance; and among the exercises in the gymnasia they probably laid as much stress on an even pace in the long races as on speed. But when running was practised at the contests, the moderation in speed of course gave way to the attempt to be first in the race and in consequence we hear of cases in which the victorious runner, on reaching the winning-post, fell down dead in consequence of excessive exertion, like the runner Ladas, whose statue Myron made. Therefore, the runners, as well as others who engaged in gymnastic contests, were in the habit of previously rubbing their bodies with oil in order to make their limbs flexible. In running, three or five generally entered at the same time; when there were more they seem to have been divided into parties of four, and in that case the winning party had to run once more to decide the final victory. The signal for running was given by the dropping of a rope stretched out in front of the runners; in running, they either held their arms with the elbows closely pressed to their sides or swung them violently and regularly backwards and forwards, corresponding in time to the feet; the former attitude
