Knoxville Marathon Split Comparisons
Having a consistent pace throughout a marathon is the ideal strategy. However, it's not easy. Looking at the splits in Knoxville's March 20th Marathon, only about 20% of the runners were able to keep their first and second half times within 5 minutes of each other. About 76% ran the second half over 5 minutes slower. Only 9% of the runners ran the second half faster.
This is similar to other marathons that I've looked into. For example, in the Virgina Beach Marathon there were also only 9% who finished faster. Like Knoxville, Virginia Beach also had cool weather throughout the race.
As was mentioned only about 20% of the runners were able keep their first and second half times within 5 minutes of each other. The faster runners were more likely to achieve this. Here's a summary by chip finish time and the percentages of those who had about equal splits (+/- 5 minutes).
under 3hr: 47%
3 to 3.5hr: 47%
3.5 to 4hr: 28%
4 to 4.5hr: 19%
4.5 to 5hr: 9%
5 to 5.5hr: 8%
5.5 to 6hr: 5%
over 6hr: 11%
Overall: 20%
Below are the stats in table formats derived from the Knoxville Marathon results page. The halfway times are assumed to be chip times.
