A flexible but user-friendly running pace calculator as a command line tool.
$ pip install running
Call running with two of the three arguments pace, distance or time, and it will calculate the missing one for you.
$ running --pace 4:30/km --distance marathon
Elapsed time: 3:09:53 [H:]MM:SS
You can also just use the first letter of the argument names:
$ running -p 4:30 -d marathon
Note that distance unit for the pace was omitted, defaulting to kilometer. This can be changed with the unit (-u) parameter as follows:
$ running -p 8:00 -d 10km -u miles
Elapsed time: 49:43 [H:]MM:SS
You can also directly specify the units for the pace:
$ running -p 6min/mile -t 1hour
Travelled distance: 16.09 km
$ running -d half-marathon -t 1:45:00
Required pace: 04:59 /km
The tool is quite flexible in terms of the valid expressions for the arguments, see running --help for more examples.
Ever wondered how fast Usain Bolt would run a marathon?
$ running -p bolt -d marathon
Elapsed time: 1:07:22 [H:]MM:SS
