Calculating running pace in Microsoft Excel is quite simple. You can use the formula to calculate your running pace. Here's how you can set it up in your spreadsheet:

1. Create a new column for your running pace. You can label this column "Pace" or "Mile Pace."
2. In the first cell of the Pace column, enter the formula
   Code:

   "=time(0,0,Distance/Time)"

   where "Distance" is the distance you ran (in miles) and "Time" is the time it took you to run that distance (in minutes).
3. Press Enter to calculate the running pace for that row.
4. Copy the formula down the entire column to automatically calculate the running pace for each row.
5. You can format the cells in the Pace column to display the time in a more readable format. Right-click on the cells, select "Format Cells," and choose "Custom." In the "Type" field, enter "mm:ss" to display the time in minutes and seconds.

That's it! Now, every time you enter the distance and time for a run, the running pace will be automatically calculated in the Pace column. This will save you time and make it easier to track your progress over time.
