Calculate the pace needed for a target marathon finish time.
Dividing the target time by the race distance gives the pace that must be held throughout. The halfway split is the checkpoint that reveals whether the pace is on track early enough to correct. Marathon pace must be sustainable for over three hours, and starting even ten seconds per kilometre too fast typically costs several minutes in the final ten kilometres.
