1. What is Marathon Finish Time?

The marathon finish time is the total time taken to complete a marathon (42.195 km) based on your running pace. It helps runners plan their race strategy and set realistic goals.

2. How Does the Calculator Work?

The calculator uses the marathon time formula:

\[ \text{Time (hours)} = \text{Pace (hours/km)} \times 42.195 \]

Where:

Pace — Your running speed in minutes:seconds per kilometer
42.195 — The official marathon distance in kilometers

Explanation: The formula converts your per-kilometer pace to the total time needed to cover the full marathon distance.
