How Does Athlytic Calculate Target Bed Time?

Athlytic’s Target Bed Time is based on its Target Sleep recommendation but also accounts for the time you typically spend awake during the night as well as your typical time you fall asleep (for optimal circadian rhythm). This ensures that you have enough time in bed to achieve your full Target Sleep duration.

Athlytic uses three key factors to determine your Target Bed Time:

✔ Target Sleep – The amount of sleep Athlytic recommends based on your Recovery, Sleep Debt, and Training Goal.

✔ Average Time Awake – The typical amount of time you spend awake during the night, calculated from Apple Health sleep data.

✔ Sleep Consistency (Past 7 Days) – The average time you actually fall asleep over the past week.

How Target Bed Time is Calculated

Athlytic calculates your bedtime differently depending on whether you choose a Target Wake Time or let it determine your wake time based on your habits.

Scenario 1: No Set Wake Time (Uses Sleep Consistency)

If you don’t manually set a wake-up time, Athlytic uses:

Your past 7-day average time asleep (your natural bedtime).
Target Sleep + Average Awake Time to determine when you’ll wake up.

Example:

Target Sleep: 8 hours
Average Awake Time: 30 minutes
Average Time Asleep (past 7 days): 2:00 AM
Target Wake Time will be 10:30 AM

This means Athlytic does not force an arbitrary bedtime but rather follows your actual sleep habits.

Scenario 2: User Sets a Wake Time

If you manually set your wake-up time, Athlytic stops using your past 7-day average sleep time and instead backs up from your chosen wake time:

Target Wake Time: 8:00 AM
Target Sleep: 8 hours
Average Awake Time: 30 minutes
Target Bed Time will be 11:30 PM

💡 In this case, Athlytic prioritizes your chosen wake time over past sleep patterns.

Why Does My Target Bed Time Seem Too Early?

If your Target Bed Time appears earlier than expected, check for:

Incorrect Awake Time Data in Apple Health

Apple Health has false awake time entries, it may be inflating your estimated awake time.

Open Apple Health → Browse → Sleep.
Scroll down and tap Show All Data.
Delete any incorrect awake samples.

Your Past 7-Day Sleep Habits

If you have inconsistent sleep times or recently started going to bed earlier, your average sleep time may be earlier than expected.
