Pace calculator

With this really easy-to-use tool, especially designed for runners, you can (for example)

• calculate your own pace in different units
• make conversions between distances in different units
• make conversions between paces in different units
• calculate target split times in many ways

A few seconds per mile during a marathon is the difference between finishing with the Kenyans and finishing with some guy named Ken.

Instructions

The pace calculator can be used in many different ways and here I list some of the functionality that I have found useful. You will probably find many other ways to use the calculator. Try it, you'll love it!

Features and functionality

• You can define the distance (in kilometers, miles, meters, yards or 400m laps) and time (hours, minutes and/or seconds). Then the pace in several different units can be calculated.
  For example, define 5 km in 20 minutes and you'll get this result.
• You can define a pace in one specific unit (minutes per km, minutes per mile, minutes per 400m, minutes per 100m, meters per second, kilometers per hour or miles per hour). Then the pace can be converted to other units.
  For example, define 4 min/km and you'll get this result.
• You can define a pace in one specific unit (minutes per km, minutes per mile, minutes per 400m, minutes per 100m, meters per second, kilometers per hour or miles per hour) and the distance (in kilometers, miles, meters, yards or 400m laps). Then the time can be calculated. The pace is also converted to the other units.
  For example, define 6 min/mile for 10 miles and you'll get this result.
• You can define a pace in one specific unit (minutes per km, minutes per mile, minutes per 400m, minutes per 100m, meters per second, kilometers per hour or miles per hour) and the time (hours, minutes and/or seconds). Then the distance (in kilometers, miles, meters, yards and 400m laps) can be calculated. The pace is also converted to the other units.
  For example, define 4 min/km for 40 minutes and you'll get this result.
• If you only define a distance (in kilometers, miles, meters, yards or 400m laps) and pushes the calculate/convert button, the distance will be converted to the other units.
  For example, define 42195 meters and you'll get this result.
• You can get a table with target split times for different distances (kilometers, miles, 400m laps or 200m laps) by defining a value in the split distance in drop-down.
  For example, suppose you plan to run 5 km with a target pace of 4:30 /km. Then you fill in the pace (4:30) and 5 km in the distance field. You also define kilometers in the split distance in drop-down. Push the calculate/convert button and you can read the target split times (for 1, 2, 3, 4 and 5 km) in the table below the calculator. You also see the target goal time, which is 22:30 in this example.
  Another example is to fill in distance 10000 meters, split distance in 400m laps and 26:17 minutes as time. Then the table will contain the target split times for 1, 2, 3, ..., 24 and 25 laps, that you'll have to beat for breaking Kenenisa Bekeles world record...
  If you instead are going for Paul Tergats world record on the Marathon distance, fill in distance 42195 meters, split distance in kilometers and 2:04:55 as time. You'll see your passing times for each kilometer.

Remarks

• The decimal point to use is the dot character "." and not the comma character ",". For example, the floating point number 12.5 is valid, but 12,5 is invalid.
• The input parameters used for the calculation/conversion are marked in bold in the result column.
• If the input parameters contain errors, the errors are shown in red above the pace calculator.
• If there are blank result rows, the reason can be that the result values are to small (for example, time values less than a second are not shown).
• The distance value used by the 400m laps is the number of laps, i.e. you can think of the unit as being 400m. For example, if you define 2.5 400m laps, this is equivalent to defining the distance as 1000 meters.
• The distance result with the unit laps is always for the 400m laps. The 200m laps can only be used as a "splitting distance" in the target split times table.
• In the hh:mm:ss fields you can define the hours, minutes and seconds. In the mm:ss fields you can define the minutes and seconds. For the hours, minutes and seconds values you shall use integers. In the distance, m/s, km/h and miles/h fields you can define a floating point number.
• The link Show the Pace Calculator in a separate window can be used if you only need to focus on the calculator part and don't need all the texts surrounding the calculator.
• There is only one (1) button (named Calculate/convert) you have to use for getting your results. The reason is that the calculator is smart enough to know what calculations that can be performed. Instead of you deciding if it is the pace, the distance or the time you look for, the calculator does as much as possible from your defined input values.

Version history

• [October 2002] Version 1.0 is released. In this version you could convert between paces in different units, calculate a pace from a distance and time.
• [August 2003] Version 2.0 is released. The user interface is completely redesigned and rewritten. Many new functions are added (see the instructions above).
• [July 2005] Version 2.1 is released. The distance can now be defined in number of 400m laps. Paces for 400 meters and 100 meters are added.
• [December 2006] Version 3.0 is released. Calculation of target split times is added. Some improvements in the user interface and the HTML-code.
• [February 2007] Version 3.1 is released. Refinements of the instructions, minor bugfix in the target split times calculations and some example screenshots are added.
• [April 2007] This improved version (3.2) is released. Bugfix when defining distances in 400m laps.

Features in the future

Here is a list of features and functionality that hopefully will be added in some of the future versions of the Pace Calculator.

• Using intervals in pace definitions. By defining, for example, a distance of 5 km and a pace of 5:00 minutes per kilometer with a variation of ±5 seconds. In this case you should get the finish time for the paces 4:55 and 5:05 minutes per kilometer, i.e. 24:35-25:25 minutes.
