Analyze Steamboat 4 mile Finisher dataΒΆ

  • Github page with source code for gathering data and performing analysis

In 2019 the Steamboat 15K race changed from running up and down the Steamboat hills 2 times to 3 times. Want to determine if the change to the course resulted in faster or slower finisher times.

Have done these calcualtions using Average and Median. Both gave similar results with a larger difference using Median. Showing results with Average as I am more used to that statistic.

  • Finishing time for top 3 of each age groups for each year
  • Finishing time for top 3 of each age groups for 3 years of 2 hill loop course and 3 years of 3 hill loop course

Comparing average finish times by age group for each yearΒΆ

  • dashed lines are for 3 loop course

Viewing each individual race can be hard to tell if finishers averaged faster or slower times based on the course change.

Comparing average finish times for 2 versus 3 times up Steamboat HillΒΆ

Combine finishing times for 2016 through 2018 into β€œ2 loop course” and 2019, 2022, and 2023 into β€œ3 loop course” and get the average for those groups.

Can see the mens finishing times are always faster with the 3 loop course and the 3 loop course is usually faster for women.

This indicates the new course is faster despite going up the Steamboat Hill 3 times instead of 2 times.

Finish times of top three by age group for each yearΒΆ

Using the top 3 finishers for each age group the average finish time for men and women is much closer indicating the top 3 finishers for each age group was not significantly impacted by the course change.

Use Average as the outliers are being removed since only looking at top 3 finishers

The Average Age Group pace change for 2 loop versus 3 for males and females for top 3 finishers is not very large. The Average is lower than the average improvement for any age groups that got faster for male or females.

M 0:09/mile

Other factors that will affect finisher timesΒΆ

  • The starting temperature for the race was better for each of the years that had the 3 loops of the Steamboat Hill when compared to the 2 loop years. The improved weather could be causing the improved performance instead of the change to the course.
  • The number of finishers for the 15K are lower with the 3 loop course compared to the 2 loop course. So could have less slower runners resulting in the different average finishing times.
