TrainingPeaks and intervals.icu, connected to your fueling
Connect either platform and your planned workouts arrive in Saturday with the fuel plan built. Send the plan back to the workout with one tap, or let Saturday post it for you. Here is what each connection reads, what it writes, and how you stay in control.
BLUF: How we safeguard your data, bottom line, up front.
We read your training history. The only thing we write back is your fueling plan: a comment on the matching TrainingPeaks workout or intervals.icu activity, and on intervals.icu the planned carbs per hour on the calendar entry. Comments post only when you tap Send or turn on auto-send. On intervals.icu, Saturday automatically sets planned carbs per hour when the calendar entry has no figure or still has the one Saturday set. Replacing a figure you or your coach entered requires your permission. We train our models only on data from sources whose terms permit it. We never sell your data and never use it for ads. Disconnect any time and we stop syncing; the Activity-Platform Integration Disclosure sets out what happens to the workouts already imported.
The two platforms that connect today
Each card shows what Saturday reads from the platform, what it writes back, and how we credit and use the data.
- TrainingPeaks Not used for training
- What we read
- Your planned workouts for the week ahead, including races and brick sessions, with their structure and descriptions. Completed workouts with their power, heart rate, pace, and TSS.
- What we write back
- Your fuel plan, as a comment on the matching workout. Tap Send on the activity, or turn on Auto-send nutrition to TrainingPeaks in Preferences and Saturday posts it as you leave the activity. TrainingPeaks does not let apps edit comments, so an updated plan posts as a new comment.
- How we credit it
- TrainingPeaks icon beside each imported workout in your activity list
Not used to train our models. Saturday never changes or deletes your workouts.
- intervals.icu Can train our models
- What we read
- Your planned workouts for the week ahead with their power, heart-rate, or pace targets, completed activities with per-second streams, and wellness (HRV, sleep, resting heart rate, readiness, VO2 max, weight).
- What we write back
- On a planned workout, Saturday sets the carbohydrates-per-hour figure on the calendar entry to your plan's figure. It does this on its own when the entry has no figure or still has the one Saturday set; it replaces a figure you or your coach entered only if you tell it to (Yes, Always when the app asks, or Auto-send carbs to Intervals.icu in Preferences). On a completed activity, Saturday posts one comment with the fuel, hydration, and electrolyte plan for that session when you tap Send, or on its own if you turn on Auto-post nutrition comments in Preferences. When your plan changes, Saturday edits its comment rather than adding another.
Our fastest, deepest connection. It aggregates many of your other devices, so their workouts reach Saturday through it.
How connecting works
-
You connect, with your consent
In the app, open My Profile, tap Sync Your Apps, then tap Connect beside TrainingPeaks or intervals.icu. You sign in on the platform’s page, which shows what you grant before you grant it. Nothing imports until you say yes.
-
Your workouts arrive with the fuel plan built
Saturday syncs the week ahead each time you open the app and builds a fuel, hydration, and electrolyte prescription for every planned workout, matched to its sport, duration, intensity, and the weather.
-
Comments post when you send them or turn on auto-send
Tap Send on the activity and Saturday posts the plan as a comment on the matching workout. Turn on auto-send in Preferences and it posts for you. Saturday never changes or deletes your training data on either platform. On intervals.icu, Saturday automatically sets planned carbs per hour when the calendar entry has no figure or still has the one Saturday set. Replacing a figure you or your coach entered requires your permission.
-
You stay in control
Disconnect any time from Sync Your Apps in the app or from the platform itself. We stop syncing, and the Activity-Platform Integration Disclosure sets out what happens to the workouts already imported.
How we use your data to improve
Saturday can get better by learning patterns across many athletes. When we train our shared fueling models, the training data is keyed to an internal account number, never your name or email address, and we use data only from sources whose terms permit it: intervals.icu qualifies. TrainingPeaks data is excluded from that training. If you are 18 or older, workouts from either platform also tune the personal pace estimate Saturday keeps for you.
We do not connect to, import from, or train on Strava or Oura at all.
Delete any time
Delete an activity in the app and we delete it from your account and our analytics warehouse within 24 hours, and the original file a platform sent us for it within 32 days. Delete your account and we delete your account data, from every connected platform, within 24 hours; backup copies expire within 84 days and data warehouse copies within 100 days. The App Privacy Policy lists the few records we keep after deletion and why. We do not currently use any fueling model trained on athletes' data. When we train one, it learns only from the data we hold at the time, so data you delete stays out of every model trained once the deletion is done.
