Each displayed time is rounded independently to the nearest second. The finish uses the exact target.
Your target and its pace
A 3:15:00 finish over 42.195 km corresponds to 4:37/km or 7:26/mi when shown to the nearest second. This page uses an even pace: equal distances receive equal shares of the original target time.
The finish is 3:15:00 and halfway is 1:37:30. A 5 km band has its halfway marker between 20 km and 25 km. Keeping that distance label prevents the extra row from being read as another 5 km segment.

Check the cumulative splits
The cumulative split table includes each whole kilometre, halfway if it is a separate marker, and one exact finish. These values are elapsed time since the start. Changing the display unit relabels those same checkpoints; it does not move them to whole-mile markers.
Read the final segment
The last whole-kilometre checkpoint before the finish is 42 km at 3:14:06. The remaining 195 m takes 0:00:54 when rounded separately. Adjacent displayed values can differ by one second from a separately rounded segment; the original target is not adjusted to hide that effect.
Edit the plan or make a band
Open this target in the split calculator to change the marker interval or display unit. In the pace-band maker, choose A4 or Letter, a band size and a short label. Preview all strips and check the finish before exporting. The preset starts at an even allocation; any two-half change should be an explicit choice.
