How to Calculate Training Load

What is Training Load?

Training load quantifies exercise stimulus using the session RPE method: RPE (1–10) × Duration (minutes) = Arbitrary Units (AU). Weekly monitoring helps prevent overtraining and injury.

Formula

Training Stress Score = (Intensity % × Duration minutes) / FTP × 100 | Chronic Load = 42-day average

Step-by-Step Guide

  1. 1Session load (AU) = RPE × Duration (minutes)
  2. 2Weekly load = Sum of all session loads
  3. 3Optimal adult range: 300–800 AU/week depending on experience
  4. 4Acute:Chronic workload ratio 0.8–1.3 minimises injury risk

Worked Examples

Input
Run: RPE 7 × 50min = 350 AU; Gym: RPE 6 × 40min = 240 AU
Result
Weekly so far: 590 AU — optimal range
