The 'Total Run' of a stairway is

Explanation:
Total Run is the overall horizontal distance of the stair, so you determine it by adding up the horizontal portions of each step—the tread runs. This measures how far the stair stretches forward across the floor plan. It’s not about vertical height (that would be the total rise or sum of risers), not a ratio (rise divided by run), and not simply a count (the total number of risers). For example, if there are 12 treads each with a 10-inch run, the total run is 120 inches.
