It's the end of the season, and we can now truly compare certain stats year-over-year. Are the fast athletes getting faster? And by how much? Did athletes have to drop significant amount of time to become competitive? Well, how much?
We took the 2018 personal bests of the athletes who contested the 1500m and 1600m for their respective gender, and then compared those against their bests from the year before. See what it took to move up the leaderboards one year later.
