More Pace Variation and Pack Formation in Successful World-Class 10,000-m Runners Than in Less Successful Competitors.

The ability to undertake a high degree of pace variability, mostly characterized by acceleration in the final stages, is strongly associated with achievement of high finishing positions in championship 10,000-m racing. Furthermore, the adoption and maintenance of positions close to the front of the race from the early stages are important to achieve a high finishing position.
