Your A race now picks the training you get, and athletes can connect their own Intervals.icu account without copying an API key.
Put your A race on the calendar and the plan builds toward it: the race's type and your expected finish time pick the kind of training — time trial, criterium or gran fondo — not a setting you chose once. A C race only sets the race day. Where a race can go either way (road race, gravel, mountain bike), add an expected finish time and the plan follows; until then your fallback applies. The plan builder says which it is: "Trained as …".
New: Connect with Intervals.icu. Link your Intervals.icu account under Settings → Connections without copying an API key: approve Breakout on Intervals.icu and you are connected. Already connected with a key? Switch there — we then no longer store your key, and you can remove Breakout from Intervals.icu at any time. Coaches who import athletes keep using their own API key.
Your plan follows the season week by week. A plan that runs from Base into Build is now built as Build from that week on, not in the phase it started in. Each week in the plan builder shows its phase, and the Season plan shows your whole season with today marked. After an A race, the season carries on toward your next A race.
Settings → Training, reorganised. It opens with "What you train for": your target race and the training it gets, then the fallbacks used only when no A or B race is planned — bike profile, run distance, multisport race distance. The old "planning mode" is gone; the race calendar and one fallback are all there is.
Feedback gets a receipt. After you send feedback you receive a confirmation e-mail with its reference; our reply reaches you at the same address.
Carbs burned to Intervals.icu, on by default. Once you have a measured fuel curve, each ride's carbohydrate use is written to Intervals.icu on the next sync. Switch it off under Settings → Training → Bike settings.
Events in loaded weeks. A week whose C races already carry most of its load no longer blocks the plan: the training beside them is thinned instead.
Release notes by e-mail. One mail per release, never more than one a week. Switch it off under Settings → Email notifications.
The whole app, your workouts and plan messages, the emails and the help pages are available in Spanish, for Spain and Latin America alike. A browser set to Spanish opens Breakout in Spanish; otherwise switch under Settings → Language.
Weekly HRV trend. The Progress page reads this week's 7-day HRV mean against last week's and shows a small chip when the trend turns, so one odd morning no longer moves the picture.
Transition sessions. Generated duathlon plans put one bike-to-run transition session a week in the final three weeks before the A race.
Booked tests. A week that holds a booked test is planned around it: no hard session the day before, lighter days after, and the week's target is what the test week can carry.
Coaches especially welcome. A roster of your athletes, their tests and physiology in one place, plans you build or generate and adjust before they go to their Intervals.icu calendars.
Getting started. A setup guide for self-coached athletes, coached athletes and coaches; new accounts get a short checklist with progress on the dashboard. Coaches who also train can plan their own training next to their athletes.
Help where you need it. The (?) help panel now also covers the coach roster, reports, race power, Nutrition Today, running physiology, race plans and duathlon.
Race plans. The race card says where your race power comes from, a target NP you type always wins, and the NP and finish time go onto your Intervals.icu race event. Race days are planned from the actual race, and a duathlon on a cycling plan books both bike and run. Simpler race-type menu (gravel counts as a road race).
Nutrition. Race-day drink cues add up to your prescribed fluid; training-day caffeine follows the training rules and respects caffeine sensitivity.
Runners. Daniels T and I paces from the published per-km tables, 400 m lap times on repetition cards, a glycogen check for your race, and a marathon or half suggestion when a running race has no distance yet.
Planner and dashboard. Ramp shown per discipline, no hard session the day before a booked test, and your time zone is picked up from your browser.
Fixes. No more crash with Chrome's page translation, pages no longer jump while loading, tabs scroll sideways on a phone, nicer emails, and LT1 and LT2 name the test they came from.
The whole app, your workouts and plan messages, the emails and the help pages are available in German. A browser set to German opens Breakout in German; otherwise switch under Settings → Language.
Running. Separate run profiles (threshold pace, heart rate, VDOT) next to your bike numbers, run tests picked straight from your Intervals.icu activities, and running race plans with aid stations and fuelling.
Every value says where it comes from. Measured, calculated from your test, or estimated, with a short help page per label. When a number is only an estimate, the app names the test that would replace it.
Daily wellness history on the Progress page: HRV, resting heart rate and sleep over 12, 26 or 52 weeks.
Sharper race nutrition and recovery. Carb loading, pre-race meals and drinks, in-race fuelling by event length, rehydration and recovery carbs reviewed and tightened against current sports-nutrition guidance.
Breakout connects your test results with training towards your goal and personalised session fuelling, alongside Intervals.icu. The beta is free; paid subscriptions come at launch.
Put your tests to work. A lactate step test gives LT1 and LT2 from your recorded curve; a three-effort cycling Powertest estimates VLamax and MAP. Every result says whether it was measured, calculated from a test, estimated, or set by you or your coach.
Plan towards your goal. Bike and run planners use your recent training, your goal race and the hours you have each weekday. Edits you make survive regeneration, and a structured workout builder covers bike, run and manual swim sessions.
Connect training with fuelling. Estimated carbohydrate use and fuelling guidance per session and per day, plus race pacing and fuelling plans. Estimated burn and planned intake are shown separately.
Deterministic engine. Decisions come from rules and calculations, never from a language model. The same inputs give the same plan, and you or your coach review it before it goes to your Intervals.icu calendar.
