How to Actually Track Your Running PRs (And Why Most Runners Get It Wrong)
Your Personal Records are the clearest measure of progress in running. Here's why manual tracking fails, and how OnRun keeps every PR automatically — across every distance you've ever raced.
Ask ten runners what their half marathon PR is, and nine of them will pause, squint, and say something like "I think it was around 1:52? Maybe 1:49? Hold on, let me check my phone."
The tenth one has it memorized because they ran it last weekend.
This is the PR problem. You work months to shave two minutes off a distance. You cross the line, glance at your watch, feel that wave of satisfaction — and then that number starts to fade. By the time you're training for your next race, you're not entirely sure what you're chasing.
Why Spreadsheets and Notes Apps Fail
The classic approach is to keep a running document somewhere. A note. A spreadsheet. A sticky note on your monitor that says "HM: 1:51:34" in fading ink.
Here's the problem: race data is scattered across a dozen different places. Your results from a race three years ago are on a timing company website that may or may not exist anymore. Your Garmin tracks your training runs beautifully but treats your Sunday 5K race like just another tempo effort. Your Strava feed buries that marathon finish under 400 Tuesday night jogs.
There's no single source of truth. So you either maintain the spreadsheet obsessively, or you let it lapse and lose the thread.
What a PR Actually Means
A Personal Record is more than a fast time. It's a data point on a curve. It tells you where you were at a specific moment in your development as a runner. The trajectory of your PRs over years is the real story — and that story is worth preserving.
Did your 10K drop from 58:00 to 52:00 to 49:30 over three training cycles? That's not just three numbers. That's evidence that a training approach is working. That's something to show a coach. That's something to look back at when training feels hard and you can't remember why you do this.
How OnRun Tracks PRs
OnRun does two things that make PR tracking effortless.
First, we automatically import your official race results. When you connect your profile, OnRun finds your results from thousands of races — finisher times, official gun splits, chip times, age group placements. No manual entry. No hunting through old confirmation emails. The data is just there.
Second, we identify your PRs automatically across every standard distance. 5K, 10K, 10-mile, half marathon, marathon. OnRun scans your complete race history and surfaces your best time at each distance. It updates in real time as you race. When you run a new PR, it's recorded the moment your result hits the timing database.
The Progress Chart You've Always Wanted
The real payoff isn't just knowing your current PRs — it's seeing how they've moved.
OnRun builds a visual progress chart for each distance you've raced. Plot your 5K times over the last five years and you'll see something you can't get from a spreadsheet: the shape of your improvement. The plateau after an injury. The breakthrough after you switched to higher mileage. The slight regression when life got busy.
That visual feedback is motivation in a format your brain can actually process.
Racing More Purposefully
When your PR history is organized and visible, you start racing differently. You stop guessing at goal paces. You stop setting vague intentions like "I want to run a good half marathon." You run with a number in mind — because you know exactly where you stand.
"Beating my PR" is a clear, measurable target. OnRun makes it easy to set that target every time.
Your PRs tell the story of your running life. They deserve better than a faded sticky note. Set up your OnRun profile and let your race history speak for itself.
