Abstract

Academic libraries exist to support the educational goals of their parent institution; one of such roles being to provide. This paper presents analysis of long distance running (44 km) in the 2011 Olympus Marathon in Greece, EU. The course consists of 21 km of an ascending leg (mean leaning angle of 7 degrees) and 23 km of a descending leg (mean leaning angle of 6 degrees). It starts at 3 m above the sea level, runs up to the summit at 2780 m and descends to the level of 320 m. From about 500 runners, the first 50 to reach the finish line were investigated. Their mean velocity over the whole course differed significantly, but the distribution of velocity along the whole course was similar for the 10 first runners at the finish, for runners from places 11 to 30 and for those from 31 to 50. It was anticipated that running uphill would be slower and running downhill would be faster, but the last fragment of the marathon (descending) was run with similar velocity to the first fragment (ascending). This was due to the level of fatigue experienced by the runners. Apart from the rest, the winner ran the last sector faster, as has been previously seen for other world level runners and for sportspersons in other long distance sport disciplines presented in other articles. The winner had an ascending mean velocity of 2.29 m/s, a descending mean velocity of 3.14 m/s and a mean velocity for the whole race of 2.67 m/s, with a standard deviation of 6 fragments equalling 0.576 m/s. Fluctuation of velocity (standard deviation/mean velocity) was smaller for better runners compared to the worse runners.
