Breakout is the Intervals.icu-native lab that turns your tests into training, fueling, and key-day execution — every number traceable, the coach always in the loop.
Most tools guess your physiology from your rides. Breakout measures it — and shows its work.
Lab, lactate, or field test — your profile is built from real measurement, and every value carries its source, freshness, and confidence. When a number is an estimate, we say so.
One path, no spreadsheets: test → understand what changed → train the right thing → fuel it → execute the key day. Every step reads from the same measured profile.
Your key days get an event-aware script: pacing by segment, carbs per hour, a bottle-by-bottle fuel strategy, pre-event loading — built on your metabolism, not a template.
Coaches see who's ready, stale, or blocked before the week starts, and keep every plan their call. Breakout sharpens judgment; it doesn't replace it.
A lab test anchors your profile. A field powertest tracks progress between labs. Your Intervals.icu history watches the trend day to day. Breakout always uses the best tier available — and shows you which one it is.
A weaker tier can suggest an update — it never silently overwrites a measured truth.
Upload the route. Breakout builds the pacing plan and the fuel strategy for the terrain — how hard on the climbs, how much to carry, what to take and when — then verifies how it actually went, so the next event is sharper.
Bring your roster into one view — testing freshness, plan readiness, sync status, compliance, race readiness, and an action queue that surfaces what needs you. Review plans, set the phase, push clean workouts to Intervals.icu. Your athletes, your call, your numbers.
Breakout is in private launch with a small group of athletes and coaches. Join the list — we'll email you when there's a spot.
