In the UK they call it the PB. In the US, we call it a PR, or a personal record. In other words, whatever your best performance is for a distance you race.
It is your own “world record” or a measure of how you have performed your best for some measured distance in your whole life. Or some segment of your life if you consider things like “the master’s PR” or some other significant to you milestone.
PRs are important to all of us, but it is pretty clear to me that they are very important to the kids I work with on the local HS team. Some of this is driven by the so called information age we live in. Every officially timed track meet ends up in a web database somewhere, and it becomes your own personal brand of performance. If you are a kid that is vying for a state track meet spot, you have to put up a performance that is one of the top 18 in the state to make it to that meet in Colorado (for most divisions). You become very aware as to where you stack, what your performance means, and if you are “good enough.”
Even for the kid who is not a state level athlete, they naturally want to have objective evidence that they are improving. They put in a dozen or so hours a week on the roads, track and trails in training to run as fast as they can around a track for two or four or eight laps. With that sort of investment, it is appropriate that they want to see a return.
I encourage a focus on PRs too. When a kid PRs, it is a big deal and I congratulate them as such. They have done something they have never done before, and at some point in their life may never do again.
Inevitably when speaking to a runner the topic of PRs comes up. What was your best mile, 10k or marathon? What was your best performance at Leadville or Pikes? How fast were you in high school or college or as a master? In fact, when a runner says to me that they were a serious runner at some point in their life and they can’t recall their PRs, they tend to lose some degree of credibility. Remember when US House Speaker Paul Ryan claimed a PR for the marathon that was inaccurate? The back lash, especially in the running community, was pretty negative.
But the focus on numbers, and PRs can be a problem.
When kids show up to a race and it is too windy, too cold, too hot, too whatever … in other words the conditions are not ideal, and not “PR weather” they can take a dim or less than positive view of how they are expected to perform. Or they don’t “feel” good and hence begin to think that because things are not perfect, they won’t perform perfectly.
So while there is a consideration of PRs (or splits, or other numbers), it is not the whole consideration. In fact PRs are not even the most important factor. It is how you have performed for you on that day. How did you compete? How did you react to that competitor making a move in the race? How did you respond on lap three? What did you do when the pace went out too fast? How did you overcome the weather or your less than snappy feeling legs? How did you feel about how you felt?
This seems hard because it is less tangible to measure than a very objective number. But we completely understand it.



These pics above are samples from races where the finish time either didn’t matter and/or are significantly less than what would normally be expected. But arguably, those races are pinnacle moments for each of the athletes careers and how they are considered as competitors. Their PR is not what is considered most important when the body of their competitive work is reviewed – but rather performances where they overcame the odds, the weather, their competitors, and … themselves.
Competere in Latin means "strive in common, strive after something in company with or together or to seek together.” We seek a greater self than a PR in our competition, and so while a PR is likely to be an outcome from that, it should not be the only or most important outcome we seek.
For me as a coach, I will continue to seek how to motivate and compel student athletes to these outcomes over a focus on the PR outcome, but it is clearly not a one or the other affair.
