# Free Tools
Free tools for ultra-distance and audax riders. No sign-up required.

## Ultra-Distance Fuelling Planner
Fuelling Planner: /tools/fuelling-planner - Enter event details and food choices to generate a personalised fuelling plan and printable pocket card.

## Critical Power & W' Calculator
CP Calculator: /tools/critical-power-calculator - Enter three maximal efforts (recommended: 3, 5, and 12 minutes) to calculate critical power (CP), W' (work prime), and estimated FTP using OLS regression on the linearised CP model (P = CP + W'/t). Outputs: CP in watts, W' in kJ, estimated FTP (CP × 0.96), model fit (R²), power training zones (Coggan 6-zone, polarized 3-zone, Coggan 7-zone), power-duration curve, and a predictor for max power at a given duration or max duration at a given power. Includes progress comparison across tests and ultra-distance pacing guidance. CP is the aerobic ceiling — for ultra-distance events target 70–85% of CP; W' governs surge capacity above that ceiling.
