WHAT’S INSIDE

What’s Inside the parkrun PB Calculator

Inside this guide, you’ll find a simple table of common parkrun finish times with the realistic improvement ranges runners can typically achieve. Instead of guessing what your next PB should be, you’ll know exactly how much progress is possible based on your current fitness. This helps you train smarter, avoid pushing too hard too soon, and see the steady improvement that leads to PB breakthroughs.

I’VE BEEN IN YOUR SHOES

I Know Exactly Where You’re Coming From

As a running coach who’s helped everyday runners for 25 years, I know the biggest frustration isn’t the training — it’s not knowing what’s realistically possible. Many runners push too hard, choose unrealistic PB targets, or give up because progress feels slow.
This is why I built the PB Calculator. It gives you clarity, confidence and a clear next step. Once you know the right target for you, the training becomes easier — and the results come faster.
