The half and the full are not round numbers

How to read this

  • Pace is the time for one kilometre, so a smaller number means faster.
  • To get speed, divide 3600 by the pace in seconds: 300 s gives 12 km/h.
  • A finish time is simply the pace multiplied by the distance.
  • Mile pace is kilometre pace times 1.609344.
