True Age Grading for the devoted runner.
Standard age grading compares you to world records — an impossibly high bar that leaves most runners feeling like they're failing. TAG Running takes a different approach: benchmark yourself against your local Parkrun course records instead. Finally, a fair and honest read on where you actually stand.
The challenge
01
World records as the benchmark
Traditional age grading tables compare runners to world-record pace. For recreational runners, this produces scores so low they feel meaningless — and discouraging.
02
No local context
Every Parkrun course is different. Hills, terrain, altitude — they all affect times. A runner on a hilly course was being judged against the same standard as someone on a flat one.
03
Opaque scoring
Most grading tools give you a percentage with no explanation. Runners had no way to understand what the number meant, how to improve, or whether their progress was real.
04
Scattered data
Course records lived on individual Parkrun pages. There was no tool that aggregated them into a single, usable reference for genuine local benchmarking.
The approach
1
Redefine the benchmark
Instead of world records, TAG uses each course's own age-category records as the reference point. Your 5K is graded against the best that's been run at your specific venue — a standard that's ambitious but real.
2
Course record aggregation
Course records are scraped and maintained across UK Parkrun venues, giving the grading engine a live, local reference database rather than static global tables.
3
Clean, readable output
The interface is built around a single clear result. Runners get a grade, a context sentence, and a visual — not a wall of numbers. The score means something because the benchmark means something.
4
No login, no friction
Enter your time, your age, your course. That's it. TAG Running is deliberately low-friction — a tool you reach for on a Saturday morning without thinking, not a platform that demands your data first.
