SplitElapsed

Pick a race or type any distance, then enter a finish time to get your pace, or a pace to get your finish time. The splits table gives you every km or mile so you can write them on your arm or set your watch.

The "same pace, other races" table is not a race predictor. It shows what you'd run at exactly the same pace, so treat the longer distances as a ceiling, not a target.
