You can use Running Pace to easily compute your running pace. Just enter your distance and time, and your pace will be shown. Alternatively, enter your pace and the total time required to hit this pace will be displayed. Additionally, you can enter a split or lap distance and times at each split increment will be shown. You can enter distances in miles or kilometers. You can also set the system preference for "Metric System" to be on or off, causing defaults to be either miles or kilometers, and to control whether paces are displayed in minutes per mile or minutes per kilometer.
