(This is the 13th post in a series that started here)
I wanted to see if the trends in runners’ paces over the last 2K on the flatter course were consistent with what we saw at Boston and New York.
Here’s the 5K pace chart for Chicago:
Once again, the faster runners were relatively slow over the last 2K, while slower runners picked up their pace.
The new chart reveals another pattern: as the courses get easier, more groups run faster over the final 2K. At Boston, the first group to pick up the pace at the end were the 4:00-4:29 runners. At Chicago, the 3:00-3:29 group managed the feat. And at New York, which most people think falls somewhere in between Boston and Chicago in difficulty, the 3:30-3:59 group was the first to speed up at the end.
I look at the difference between 5K splits for men and women in my next post.
