The short answer
The average mile time for a 13-year-old is roughly 6:35 for boys and 7:15 for girls among kids who race. A good time is under 6:10 for boys and 6:50 for girls. Seventh and eighth graders at the front of national youth races run 4:45 to 5:05 and 5:15 to 5:35.
Key takeaways
- Typical racing 13-year-olds: 6:15 to 7:05 for boys, 6:55 to 7:45 for girls
- Boys make their biggest one-year jump between 13 and 14; girls improve more evenly
- Under 5:40 for a boy or 6:15 for a girl is a strong USATF 13-14 division mark
- Middle school 1600m times and mile times are interchangeable for benchmarking
- A 13-year-old who runs 20 to 25 miles a week is already ahead of most freshmen
What is the average mile time for a 13-year-old?
Thirteen is the first year most kids race the distance with a purpose. Seventh and eighth grade track programs run the 1600m, cross country has taught the aerobic base, and the USATF 13-14 division means a 13-year-old is now racing 14-year-olds in the summer. The median 13-year-old boy on a spring results list runs about 6:35; the median girl about 7:15.
Those averages hide an important split. A 13-year-old boy who has not started his growth spurt often runs the same time he ran at 12, while a boy who has can drop 40 seconds in one season without training any differently. Girls tend to improve on a smoother line. The tiers below are for the age as a whole; the side-by-side table underneath shows where the year sits.
Mile benchmarks at age 13
| Tier at age 13 | Boys | Girls |
|---|---|---|
| First timed mile, no training | 7:30 - 8:30 | 8:15 - 9:15 |
| Typical (school or club team) | 6:15 - 7:05 | 6:55 - 7:45 |
| Good (top quarter of the age) | 5:45 - 6:10 | 6:20 - 6:50 |
| Strong (places at a large youth meet) | 5:15 - 5:40 | 5:50 - 6:15 |
| National class for the age | 4:45 - 5:05 | 5:15 - 5:35 |
Ages 12, 13 and 14 side by side
The eighth-grade year is the hinge. On paper a typical 13-year-old boy is 20 to 25 seconds ahead of a 12-year-old and 20 behind a 14-year-old, and a typical girl about 15 seconds either way. At the top of the age the gaps are much bigger, because the fastest 14-year-olds are freshmen training with a high school program.
The mile at 12, 13 and 14
| Level | Age 12 (B / G) | Age 13 (B / G) | Age 14 (B / G) |
|---|---|---|---|
| Typical racer | 7:00 / 7:30 | 6:35 / 7:15 | 6:15 / 7:00 |
| Good for the age | 6:15 / 6:45 | 5:55 / 6:35 | 5:35 / 6:15 |
| National class | 5:10 / 5:40 | 4:55 / 5:25 | 4:40 / 5:15 |
What national class means at 13-14
In the USATF 13-14 division the 1500m, not the mile, is the championship event. The boys' national final was won in 4:11.14 in both 2024 and 2025, and the meet record is 4:05.25; the girls' final went in 4:46.34 and 4:41.84. Those convert to roughly 4:29 for the boys and 5:02 to 5:07 for the girls over a mile.

What is a good mile time for a 13-year-old boy?
Under 6:10 is good. Under 5:40 is the kind of time that places at a state-level middle school meet or a USATF association championship. The boys at the front of eighth-grade nationals run 4:45 to 5:05, and a handful every year go under 4:40. If a 13-year-old boy is running 6:00 to 6:30 with a smooth stride and an even pace, he is exactly where a future varsity distance runner should be.
What is a good mile time for a 13-year-old girl?
Girls in this age group often run their best middle school times here, because the growth spurt that follows can temporarily cost speed while the body sorts out new proportions. Under 6:50 is good for a 13-year-old girl and under 6:15 is strong. The national-class girls run 5:15 to 5:35, and the very best are near 5:05. A girl who plateaus between 13 and 15 has not lost anything; she is waiting for her stride to catch up.
Where these numbers come from
- Population. Athletes with a timed mile or 1600m in a meet, from seventh and eighth grade 1600m lists on Athletic.net and MileSplit and the USATF 13-14 division. The first-timer row is a coaching estimate from PE tests and first-week-of-practice times; nobody records untrained miles on Athletic.net.
- Typical. The median of that population for the age, with the band showing the middle 50 percent. Half of all racing kids at this age sit inside it.
- Good, strong, national class. Roughly the top 25 percent, top 5 percent and top 0.5 percent of the age. National class is anchored to the USATF Junior Olympic 13-14 1500m results, converted to the mile by multiplying by about 1.075 (about 19 seconds at the 4:10 to 4:45 pace this division runs).
- The 1600m. Almost every US high school race is 1600m, nine meters short of a mile. The two are treated as one number here; the difference is noted on each page for the pace in question.
- Timing. Fully automatic timing where it exists; hand times are rounded up, not down.
The 1600m at 6:30 pace is about two and a half seconds shorter than a mile, which is why the two are treated as one number for benchmarking.
What separates 6:30 from 5:45 at this age
- Weekly mileage. The 5:45 kids run four to five days a week, year round. The 6:30 kids run when the season is on.
- A real second lap. Almost every 13-year-old fades in lap three. The fast ones learned to hold pace through the middle of the race, usually by practising 400m repeats at goal pace.
- Arm carry under fatigue. When the arms start swinging across the chest the stride shortens. Fix the arms and the last 200 meters get faster without any extra fitness.
- Racing often. Two or three timed miles a month teaches pacing faster than any workout, and a clip of lap three at a meet shows an eighth grader exactly where the fade starts.
