Do fast older runners pace differently from fast younger runners in the ‘New York city marathon’? The pacing in the marathon has been studied especially for the top runners, but not a fast older and younger runners similar to pacen. We have now analyzed over 300,000 runners between 2006 and 2016 the ‘New York City Marathon’. If you are looking for the runners in groups after conclusion times, the runners with the slowest final times after 5km, 10km, 15km, and 20km have the largest waste in the running speed.
In contrast, they have the largest increase in speed after 35km and 40km. The work can be found under https://pubmed.ncbi.nlm.nih.gov/28746247/
