Find your pace, the time a distance will take, or the distance you cover, then see race times and splits for that pace.
Pick what to find. Times can be typed as hh:mm:ss, mm:ss or seconds, so 5 minutes 3 seconds can be entered as 5:3.
Enter the total distance and total elapsed time at each point of a run. The calculator finds the pace of each section and your average pace. Each row must be farther and later than the one above it.
Convert a pace from one unit to another, such as minutes per mile to kilometers per hour.
Estimate how long a race will take if you hold your current pace to the end.
Pace is how long it takes to cover a set distance, such as minutes per mile or minutes per kilometer. Runners and walkers usually think in pace, while cyclists often use speed, such as miles or kilometers per hour. The two describe the same thing from opposite sides: a faster pace is a smaller time per distance and a higher speed. The calculator shows both, along with meters per minute and meters per second.
Give any two of time, distance and pace and the third follows. Pace is the time divided by the distance. The time needed is the distance multiplied by the pace. The distance covered is the time divided by the pace. The race table shows what your pace would give over common distances, and the splits show your elapsed time at each kilometer and mile.
The multipoint tool is for runs where you know your total time at several points. It works out the pace of each section so you can see where you sped up or slowed down. The converter changes a pace between units. The finish time tool takes the distance and time you have covered and shows how long the full distance would take if you kept the same pace, which is a rough guide because pace usually drifts during a long race.
Divide your total time by the distance. A 5 kilometer run in 50 minutes and 25 seconds is 10 minutes and 5 seconds per kilometer, or about 16 minutes and 14 seconds per mile.
Divide 60 by the pace in minutes. A pace of 10 minutes per mile is 6 miles per hour. The converter does this for any pair of units.
A marathon is 42.195 kilometers, which is 26.2 miles, and a half-marathon is 21.0975 kilometers. The race table uses these exact distances.
The splits assume you hold the same pace the whole way. Each split is the pace multiplied by the distance so far, for every whole kilometer and every whole mile you cover.
It assumes you keep your current pace to the end. Most people slow down over a long race, so a longer race can take more time than the estimate suggests.
