What is a personal record (PR) in running?
A personal record, also called a personal best (PB), is the fastest time you have ever run a specific distance. For example, if your best 5K time is 24:30, that is your 5K PR. Runners track PRs across multiple distances to measure their progress and set goals.
How often should I attempt a new PR?
Most coaches recommend attempting a PR every 4 to 8 weeks, depending on the distance. For shorter distances like 5K, you might race monthly. For marathons, most runners attempt a PR once or twice a year at most. Attempting PRs too frequently leads to burnout and increases injury risk.
Does age affect my ability to set PRs?
Most runners reach peak performance in their late 20s to early 30s, but many runners continue setting PRs well into their 40s, especially if they started running later in life. Age-graded calculators can help you compare your performance against others in your age group.
Should I count treadmill times as PRs?
This is personal preference. Some runners only count verified race results as official PRs. Others count any timed effort including treadmill runs. The treadmill can be slightly easier because there is no wind resistance and the belt assists your stride, so treadmill times are often 1 to 2 percent faster than equivalent outdoor times.
What is the difference between a chip time and gun time?
Gun time starts when the race starts (the starting gun). Chip time starts when you cross the start line, measured by a timing chip on your shoe or bib. For PR tracking, most runners use chip time because it reflects your actual running time. In large races, the difference can be several minutes.
How do I train to break a PR?
Breaking a PR requires a mix of easy runs, speed work, and race-specific training. For 5K PRs, focus on interval training and tempo runs. For marathon PRs, long runs and half marathon pace work are key. Consistency over 8 to 12 weeks of structured training gives you the best chance of a new PR on race day.
Is my data saved if I close the browser?
Yes. All your personal records are saved in your browser local storage. They will persist as long as you use the same browser and do not clear your browsing data. Your data stays on your device and is never sent to any server.
Can I track custom distances?
Currently this tracker supports the 6 most common race distances: 1 mile, 5K, 10K, 15K, half marathon, and marathon. These cover the vast majority of races. For custom distances or ultra results, you can use the notes field to record them under the closest standard distance.
Tips for Breaking PRs
Race with a goal time in mind
Going into a race with a specific target makes you more likely to achieve it. Use the race predictor tool to set realistic goals based on your recent training.
Track every race, not just PRs
Logging every race time, not just your best ones, helps you see patterns in your performance. A slower time on a hilly course might actually represent better fitness than a fast time on a flat one.
Give yourself recovery between PR attempts
Attempting a PR requires peak effort. Space out your races by 4 to 6 weeks for shorter distances and 3 to 6 months for marathons. This gives your body time to recover and adapt.
Choose your race conditions wisely
If you are targeting a PR, pick a flat course with cool weather. Avoid races with significant hills, extreme heat, or strong wind. The right conditions can mean the difference between a PR and a frustrating near-miss.
