The distance behind this chart
A half marathon is exactly 21.0975 km here. The 21 km checkpoint is not the finish: there are another 97.5 m. For a 2:00:00 target, the 20 km reference is 1:53:45 and the complete 1.0975 km from that point to the finish takes about 6:15.
Pace and finish-time reference
This grid uses explicit 30-second-per-kilometre steps. The mile pace alongside each row is a display conversion of that same pace, not a separately rounded input. Choose a row as a reference or enter your own target in the calculator.

Keep the finish marker
A regular interval does not always divide the full distance. The tool adds a terminal row for the remaining distance and removes duplicate markers. Cumulative rows use the original target, so the finish does not drift when displayed paces are rounded.
