Marathon Finish Time Table
This table shows marathon finish times for common paces from 6:00/mile to 15:00/mile. Find your training pace and see what your marathon finish time would be.
What Is a Good Marathon Time?
"Good" is relative. The global average marathon finish time is approximately 4:30 to 4:45. Finishing faster than average puts you in the top half of all marathon runners worldwide. Here is a breakdown by age group and gender based on aggregated race data.
Train for 26.2 with Purpose
Marathon training means months of long runs. Motera makes every one of them count by turning your miles into territory on a real map. Watch your coverage grow with every training run. Your 20-miler will capture more ground than any other runner in your area.
MoteraFrequently Asked Questions
What is a good marathon time?
The average marathon finish time worldwide is approximately 4:30 to 4:45. A "good" time depends on your age, sex, and experience. For men, finishing under 4:00 puts you in the faster half of finishers. For women, finishing under 4:30 does the same. A sub-3:00 marathon is considered elite for recreational runners, and a sub-3:30 qualifies most men for the Boston Marathon.
How do I calculate my marathon finish time from my pace?
Multiply your pace per mile by 26.2188 (the marathon distance in miles), or multiply your pace per kilometer by 42.195. For example, if you run at 9:00 per mile, your marathon time is 9 x 26.2188 = 235.97 minutes, which is approximately 3:55:58. The calculator on this page does this math instantly.
Can I predict my marathon time from a half marathon?
Yes. A common method is to double your half marathon time and add 10 to 20 minutes. A more precise approach uses the Riegel formula: marathon time = half marathon time x (42.195/21.0975)^1.06. For a 2:00 half marathon, this predicts about 4:10 to 4:15 for the full marathon. Predictions from the half marathon are the most reliable because the distance is closest to the full.
How much do walk breaks slow down a marathon?
Walk breaks add time, but less than you might think. A common run/walk strategy of running 4 minutes and walking 1 minute (at 15:00/mi walk pace) typically adds 15 to 25 minutes to your total marathon time compared to running the entire distance. Many runners find that walk breaks actually produce a faster overall time because they prevent the extreme slowdown that happens when you hit the wall.
What pace do I need to run a sub-4 hour marathon?
To finish a marathon in under 4 hours, you need to average 9:09 per mile or 5:41 per kilometer. In practice, you should train to hold a pace slightly faster than this (around 9:00/mi) to give yourself a buffer for water stops, hills, and the inevitable slowdown in the final miles.
Why is the marathon so much harder than the half marathon?
The marathon is not just twice as hard as a half marathon. Around mile 18 to 20, your body depletes its glycogen (stored carbohydrate) reserves, causing the infamous "wall." Your muscles switch to burning fat, which is a less efficient energy source. This is why marathon predictions from shorter races tend to be optimistic. The last 6 miles of a marathon feel harder than the first 20 combined.
What is a good marathon time by age?
Average marathon times increase with age. For men in their 20s, the average is about 4:15. For men in their 40s, about 4:30. For men in their 60s, about 5:00. For women, add roughly 20 to 30 minutes to each range. These are averages across all marathon finishers. The top performers in every age group are significantly faster.
Should I run an even pace or negative split in a marathon?
A slight negative split (running the second half 1 to 2 minutes faster) or an even pace produces the best results for most runners. Starting too fast is the most common marathon mistake. Your first few miles should feel almost too easy. Save your energy for miles 18 to 26 when the race truly begins.
