What is parkrun age grading?
After every parkrun, your results email shows two numbers: your finish time and your age grade percentage. The finish time is easy to understand. The percentage is where most people glaze over.
Age grading compares your finish time against the world record 5k time for someone of your exact age and gender. The closer you are to that world record, the higher your percentage. A 100% age grade would mean you just ran the world record for your age group. A 50% means your time is exactly twice as slow as that world record.
That is it. No algorithm. No secret formula. Just your time, measured against what is theoretically possible for someone of your age and gender over 5 kilometres.
How the calculation works
Example calculation
A 30-minute finish from a 45-year-old woman works out at about 51% using the 2025 standards. That is a solid result, comfortably above the average parkrunner.
parkrun says its tables are loosely based on the World Masters Athletics (WMA) standards, and it does not publish the exact figures. The calculator on this page uses the latest WMA/USATF road standards from 2025, so your result here may differ from your parkrun email by a point or so.
What the percentages mean
The running community has settled on a rough classification system for age grades. parkrun does not use these labels officially, but they are widely understood and give you a useful frame of reference.
| Age grade | Level | What it means |
|---|---|---|
| Under 40% | Developing | Below the average for your age and gender. Nothing wrong with that, especially if you are new or returning from injury. |
| 40% to 50% | Average | Broadly average for an active adult. Most regular parkrunners sit somewhere in this range. |
| 50% to 60% | Solid | A genuinely good result. You are performing better than most people of your age and gender. |
| 60% to 70% | Local class | Strong. You would be competitive at local club level for your age group. |
| 70% to 80% | Regional class | Very strong. This is the level of a serious club runner or age group athlete. |
| 80% to 90% | National class | Elite for your age group. You would be competitive at national masters level. |
| 90%+ | World class | Exceptional. These scores belong to masters athletes who compete at the highest international level. |
For context, a 45-year-old man finishing in 22 minutes scores about 64%. A 60-year-old woman finishing in 27 minutes scores about 68%, even higher. The time looks slower. The performance is equivalent or better.
Why it matters more than your finish time
Finish times are not a fair comparison between people of different ages. A 25-year-old running 24 minutes and a 60-year-old running 24 minutes are not delivering the same performance. The 60-year-old is working much closer to their physiological ceiling.
Age grading fixes this. It is how parkrun events publish a separate age-graded result alongside the standard finish order, and why you sometimes see someone towards the back of the field recording the highest age grade of the day.
It is also useful for tracking your own progress over time. If you are getting older and your times are slipping but your age grade is holding steady, you are actually performing as well or better relative to what is possible for your age. That is worth knowing.
A useful way to think about it: your age grade tells you how good a runner you are. Your finish time just tells you how fast you went on a particular Saturday morning.
The important caveats
Age grading is a useful tool. It is not a precise science. There are a few things worth understanding before you put too much weight on it.
Course difficulty is not accounted for. Age grading uses only your finish time. A 60% age grade at Whinlatter Forest, which has over 200 metres of elevation gain, is a completely different achievement to a 60% age grade at a flat tarmac course like Birchall Playing Fields. The percentage cannot tell you this.
Weather is also ignored. A headwind, a hot morning, or a waterlogged course will all slow your time and lower your age grade, but the formula does not know that. Compare your age grades over similar conditions at the same course for the most useful picture.
The reference tables themselves are imperfect. They are based on world records that are skewed by a relatively small number of exceptional athletes at each age group. Very young and very old age groups in particular can have reference times that feel unrealistic. parkrun acknowledges this.
Age grading also only covers male and female categories. parkrun is aware that this is a limitation for non-binary participants, and the sport is still working through what a more inclusive system looks like.
parkrun age categories explained
Your results show a code like VW40-44 or SM25-29 next to your name. That is your age category, and it tells you which group you are ranked against.
- The first letter is J for junior (under 18), S for senior (18 to 34) or V for veteran (35 and over).
- The second letter is M for men or W for women.
- The numbers are your age band. Juniors are 10, 11-14 and 15-17. Seniors are 18-19, 20-24, 25-29 and 30-34. Veterans go up in five-year bands from 35-39.
So VW40-44 means a woman aged 40 to 44, and JM11-14 is a boy aged 11 to 14. "Veteran" sounds harsh at 35. It is just the label.
Your category position is handy, though it depends on who turned up that week. Age grade is the fairer number because it compares you with the best possible time for your exact age, wherever you run.
Where to find your age grade
You do not have to do anything to get your age grade. It appears automatically in your results email after every parkrun. You can also see every age grade you have ever recorded by logging into your profile on the parkrun website and looking at your full results history.
Some third-party apps and browser extensions, like the Running Challenges extension, use your age grades to power additional statistics and personal bests. Worth exploring if you enjoy the data side of things.
Age grading and PB chasing
If you are working towards a time personal best, age grading is a good parallel metric to track. Sometimes the conditions or course are not right for a PB, but your age grade is still strong. That tells you the fitness is there even if the time is not.
It is also worth setting an age grade target alongside a time target. Many club runners aim for 60% or 65% as a meaningful milestone. It gives you something to chase that stays relevant as you get older, in a way that a raw time target eventually stops doing.
My own current age grade sits in the mid-50s range. Getting it above 60% is one of the things I am working towards, alongside the 50 milestone club shirt that is now frustratingly close.
Want to chase a faster age grade? Start with the course.
A flat, fast course on a good day can push your percentage up significantly compared to a hilly trail event. See our course guides to find one that suits your goals.

- What do VW, SM and JM mean on parkrun results?
- They are age categories. J is junior, S is senior (18 to 34) and V is veteran (35 and over). M or W shows men or women, and the numbers are the age band, so VW40-44 is a woman aged 40 to 44.
- What is a good age grade percentage at parkrun?
- Above 40% means you are faster than average for your age group. Above 50% is solid. Above 60% is local class. Above 70% is regional class and genuinely strong. Above 80% is national class territory.
- How is parkrun age grading calculated?
- parkrun divides the best possible 5k time for your exact age and gender by your finish time, then expresses it as a percentage. The higher the percentage, the closer you are to the world record for someone your age.
- Does age grading account for course difficulty?
- No. It only uses your finish time, age, and gender. A hilly course will produce lower age grades than a flat one for the same runner. Use it to compare performances at the same venue, not across wildly different courses.
- Where can I find my parkrun age grade?
- It appears in your results email after every parkrun. You can also see your full history on your parkrun profile page at parkrun.org.uk.
- Why does my age grade go up as I get older even if my times get slower?
- Because the world record for your age group slows as you get older. The same finish time represents a higher percentage of what is achievable for your age. Age grading rewards you for performing well relative to your age, which raw times do not.
- Can I compare age grades across different parkrun courses?
- Loosely, but not precisely. Age grading does not account for terrain or elevation, so a hilly course will produce lower grades than a flat one. It is a better comparison tool than raw times, but not a perfect one.
- What are the age grade classes at parkrun?
- parkrun does not publish official class names, but the running community broadly uses: 40% as average, 50% as solid, 60% as local class, 70% as regional class, 80% as national class, and 90%+ as world class.
