Did You Know?
How Does Improvement Tracking Work?
Percentage Formula
Improvement % = (Old - New) ÷ Old × 100. 25→24 min = 4%.
Age-Grade
WMA tables adjust for age and sex.
Training Effect
<2% = low, 2–5% = moderate, >5% = high.
Expert Tips

| Elite | 0.5–2% |
Frequently Asked Questions
How do I calculate race time improvement?
Improvement % = (Old Time - New Time) ÷ Old Time × 100. Example: 25 min → 24 min = 4%. Negative means you got slower.
What is age-grade adjusted time?
Age-grading adjusts times for age and sex. WMA and USATF publish tables. 100% = world-class for that age.
What is a good improvement rate?
Beginners: 5–15% per year. Intermediate: 2–5%. Elite: 1–2%. Consistency over 2–3 years yields best gains.
How does training effect relate to improvement?
Training effect estimates fitness gain. Higher volume and intensity = higher effect. Balance load and recovery.
Can I compare different distances?
Use equivalent performance (VDOT or Riegel). Age-grade allows cross-distance comparison.
Why did my time get slower?
Inadequate recovery, illness, heat, course difficulty, poor pacing. One bad race doesn't define fitness.
