How to use this calculator

  • Pick your sport — pace conventions differ (min/km for running, km/h for cycling, sec/100m for swimming).
  • Enter target weekly time and sessions/week.
  • Enter the relevant pace field for your sport (the others are ignored).
  • For "current weekly distance" enter your actual recent average; 0 to skip the 10%-rule check.

About this calculator

Plan a week of cardio training: enter target weekly minutes + pace, get the weekly distance + per-session breakdown + a 10%-rule safety check against your current volume. The 10% rule (popularised by Joe Henderson and Tim Noakes in the 1980s) says weekly mileage should not increase by more than 10% week-over-week to keep injury risk manageable — empirical injury-rate studies (e.g. Buist et al. 2008 Br J Sports Med) put the inflection point closer to 15% but agree that beyond that, injury rate roughly doubles. The ACSM 2018 Physical Activity Guidelines (US) recommend ≥150 min/wk moderate OR ≥75 min/wk vigorous aerobic for adult health, and ≥300 min/wk moderate for further fitness improvements. WHO 2020 guidelines mirror these. This calc surfaces both numbers so a user knows whether they are below maintenance, at maintenance, or in the fitness-improvement zone.

Frequently asked

Is the 10% rule rigorous?+
It is a heuristic, not a proven law. The original studies (Henderson 1985, Noakes 1990) drew on injury surveys without controls. Modern data (Buist 2008 Br J Sports Med; Damsted 2018 Sports Med) supports the SHAPE of the rule (large jumps = more injuries) but the exact threshold is individual. 10% is conservative; 15% is the empirical inflection in some studies.
Should beginners follow ACSM minimums or their current ability?+
Start from current ability — even 30-60 min/wk is a useful baseline if zero-to-150 is too aggressive. Build over 4-6 weeks toward the ACSM 75-150 min/wk minimum, then progress by ~10%/week.
How does swimming compare to running?+
Per-minute energy cost is roughly comparable at "moderate" effort, but swimming is non-weight-bearing so the injury-rule logic is different. The 10% rule applies less strictly to swimming than to running. Cycling is in between.
What pace should I aim for?+
Highly individual. For recreational distance running, "conversational pace" (you can speak in full sentences) is the bedrock training pace — typically 5:30-7:30 min/km depending on fitness. For improvement, structured plans (80/20 polarised — most easy + some hard) outperform "all moderate".
