Most athletes are very competitive people.
Whether competing against actual competitors, or just one’s self, athletes like to keep track of the score… or the time… or whatever the measuring stick happens to be.
Measuring performance and monitoring self-improvement is what keeps endurance athletes coming back for more. Athletes know their PRs (personal records) and naturally, they are looking to improve them.
This is our inherent nature. It’s a good thing, BUT it should NOT be the ONLY thing.
