PIRX User Guide
How PIRX works, screen by screen — your Projected Time, the five Structural Drivers, Event Readiness, Injury Risk, triathlon projection, and every component in the app, in plain English.
PIRX turns your training data into a Projected Time — a race prediction that updates after every run and tells you which seconds came from where. This guide explains how the app works, screen by screen: what each component shows, and how its numbers are calculated, in plain English.
Start here
- Projection Tile — the main number and what it means
- Predictive Injury Calendar — when to train, ease off, or rest (14-day forecast)
- Race-Anchored Projection — how real races keep the prediction honest
- Cross-Training in Your Projection — cycling, swimming, and strength all count
- Triathlon Projection — swim, bike, run, combined
- How PIRX Differs From Garmin — why your watch shows a different time
