What the tool does, how to run it, and what to expect from the result.
Pace is time divided by distance. Once your pace per kilometer is known, multiplying it by any race distance projects a finish time at that same effort, assuming a flat, even-paced effort; real races vary with terrain, weather, and fatigue late in longer distances.
A quick way to understand who this helps, what it solves, and where it connects next.
Runners checking pace from a training run or planning a race goal time.
Converting a distance and time into pace, or projecting a race finish time.
Short answers for the questions people usually have before trying a utility like this.
Yes. It is completely free, with no sign-up and no usage limits.
A flat pace projection from a shorter effort usually overestimates marathon performance, since fatigue, fueling, and pacing discipline matter far more over 26.2 miles than over a 5K or 10K.
