Overtraining Risk Calculator

Work out overtraining risk instantly with clear inputs, formula shown and shareable results.

About Overtraining Risk Calculator

Overtraining develops when load outpaces recovery, so this score combines a workload spike measure with three recovery markers: sleep duration, elevated resting heart rate and persistent soreness. A rise of 5-10 bpm in morning heart rate alongside an ACWR above 1.5 is a well-recognised warning pattern that warrants an immediate load reduction.

Formulas

Composite score

score = workload points + sleep points + heart rate points + soreness points

Workload weighting

ACWR above 1.5 scores 35 of the 100 points

Worked example

With the default values below, Overtraining Risk Calculator returns Overtraining Risk Score of 73. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • This is an estimate from population-average equations, not a medical or diagnostic assessment. Individual results vary with genetics, training history and technique. Seek advice from a qualified coach or clinician before making significant changes to training.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What is the earliest reliable warning sign?

A sustained rise in morning resting heart rate combined with falling HRV, usually appearing before performance declines.

How long does recovery from overreaching take?

Functional overreaching resolves in days to a week. Genuine overtraining syndrome can take months, which is why early action matters.
