About Marathon Pace
Marathon Pace is a simple running calculator for estimating finish times, race pace, and treadmill-to-road pace equivalents.
What it helps with
The calculator is built for runners preparing for full marathons, half marathons, 10K races, and structured treadmill workouts. It focuses on quick answers: how a target pace maps to finish time, and how treadmill speed compares with outdoor road pace.
How to use the numbers
Pace calculations are estimates. Race performance also depends on weather, elevation, course profile, fueling, training history, and recovery. Use Marathon Pace as a planning tool, not as medical, coaching, or performance advice.
