Use the following runner pace chart to calculate your estimated finish time based on your pace per mile. Pace chart shows projected finish times for paces 4:45 through 18:00. This pace chart can be used to predict 5K, Half Marathon, and Marathon finish times.

  • Pace groups available for marathon finish times: 2:59, 3:05, 3:10, 3:15, 3:20, 3:25, 3:30, 3:35, 3:40, 3:45, 3:50, 3:55, 4:00, 4:05, 4:20, 4:35, and 4:50.
  • Pace groups are set based on popular finish times and Boston Qualifying Times.
  • The pace group leaders will run “even splits.” This means that every mile will be run at approximately the same pace.
  • Think of them as a moving finish line with your goal time pinned to the back of their shirts.
