A clearer plan for your next run.

Pace Foundry is an independent collection of free running calculators. It brings pace, speed, race splits and run-walk arithmetic together in one small toolkit.

Built for a practical question

What pace gets me to my target time? What does that mean per mile? How long will each split take? Every tool starts with your numbers and shows the result without an account or subscription.

Clear limits

The tools describe scenarios rather than assess your fitness. They do not account for terrain, weather, fatigue or unscheduled stops. Choose inputs that make sense for your own circumstances.

Independent by design

Pace Foundry is not affiliated with a race organizer or a training platform. We link to source organizations for unit definitions and standard distances, not as endorsements.
