Splits assume a constant pace. Times are calculated precisely and rounded only for display.

How to use your pace and split plan

Choose a standard race distance or enter your own. Enter time as hours, minutes, and seconds. MyRunCalc divides total seconds by distance to calculate pace, then computes each split directly from the full-precision result.

For a marathon goal of 3:30:00, average pace is about 4:59 per kilometer. The actual calculation uses 42.195 km and unrounded pace, so the finish split stays exactly 3:30:00. The marathon split table also includes halfway at 21.0975 km.

Splits assume an even pace. Hills, aid stations, turns, GPS distance differences, and weather can affect actual progress. Use the plan as a reference, not a performance guarantee.

These tools provide informational estimates, not personalized medical advice. Targets do not guarantee performance or safety. Consider your fitness, terrain, weather, altitude, and recovery. For health concerns, consult an appropriate healthcare professional.
