Half Marathon Pace Calculator

The average half marathon finish time is about 2:00-2:05. A sub-2-hour half marathon (9:09/mile) is a popular goal. Competitive runners aim for sub-1:30 (6:52/mile). Elite runners finish in 58-65 minutes.

A common method is to double your half marathon time and add 10-20 minutes. The factor is roughly 2.1x your half marathon time. For example, a 1:45 half marathon projects to approximately a 3:40-3:45 marathon.

Start at or slightly slower than your target pace for the first 3 miles. Settle into your goal pace for miles 4-10. Save energy for a strong finish in the final 5K. Avoid going out too fast in the excitement of race day.
