Commonly referred as “PR”
Also known as a “Personal Best”
Refers to your best time in a race of a specific distance. So, if you run a 5K race in 28:45, that’s your PR for the 5K distance. If you run faster than 28:45 in a subsequent 5K race, then you have a new PR for that distance. So you’ll have PRs for different race distances, from 1-milers to marathons.
Experienced runners love to talk about their PRs because it helps them stay motivated to keep training and racing. Many runners keep track of their PR’s in a runners log.
