Who is behind Pace Builder
Pace Builder is an AI running coach: you tell it your goal, your fitness and your schedule, and it builds a training plan around them - then adjusts it as your actual running tells it more.
Who writes this
Articles here are published by the Pace Builder Team - the people who build the product. That is a house byline, not a pen name for a running celebrity we do not have.
We want to be straight about what that means for you. We are a software team building a coaching tool, not certified coaches or clinicians. Where an article touches something medical - injury, pain, weight - we point you to the sources we relied on, and none of it is a substitute for a doctor or physiotherapist who can actually look at you.
How the coaching actually works
Your plan is generated from what you tell us during onboarding: goal distance, target race date, current fitness, how many days a week you can run, and your heart-rate zones if you have them.
From there it periodizes the block - base, build, peak, taper - and adapts weekly. Log a run that went badly, miss a week to illness, tell the coach your weight changed, and the plan changes with you. That adaptation is the difference between this and a static PDF plan.
Why it is free
Pace Builder is free during beta. There is no credit card, no trial timer and no feature locked behind an upgrade prompt.
The honest reason: the product gets better the more real training data it sees, and we would rather spend this phase learning from runners actually using it than optimizing a checkout. Paid plans will come later, and beta users keep a lifetime discount when they do.
Your data
Your training data is yours. You can export it or delete your account and everything in it from Settings, without emailing anyone to ask.
What we collect and why is set out in the Privacy Policy - in plain terms rather than the usual wall.
Getting in touch
Something wrong, something missing, or a plan that made no sense? Write to support@pacebuilder.run. It reaches the people who build this, and being early means your feedback carries more weight than it will later.
