Race Split Times Calculator
Work out your required per-mile pace and split time for a goal race finish time.
About this calculator
Picking a goal finish time is easy, but translating that into a pace you can actually feel and hold mile after mile is where most runners go wrong, either starting too fast and fading late or banking time early that they didn't need. This calculator divides your total goal time by the race distance to give you the exact per-mile pace required, then breaks that down into split times at 5-mile intervals so you have concrete checkpoints to compare against on race day. Instead of doing that division in your head under race stress, or discovering at mile 10 that you're 90 seconds off pace with no clear sense of what to do about it, you get a pacing plan you can print or memorize beforehand. It's a straightforward tool, but having the splits pre-calculated removes one more source of race-day guesswork.
Worked example
26.2 mi in 4:00
Result: 9:09/mile pace
