I’d like to suggest adding a Jewish calendar and religious-observance scheduling option to TrainingPeaks.

For coaches working with Jewish athletes, it would be extremely helpful to have Shabbat and Jewish holidays displayed directly on the training calendar, ideally using the correct sunset-to-sunset timing rather than simply marking the Gregorian calendar date.

The most useful implementation would allow athletes to select their level of observance, such as:

• Shabbat
• Major Jewish holidays / Yom Tov
• Fast days
• Custom observance dates

These dates could then function as athlete availability constraints. For example, TrainingPeaks could warn a coach when a workout is scheduled during a restricted period, block scheduling if the athlete chooses that setting, or help shift the workout elsewhere in the week while preserving the intended training load.

This would be particularly valuable for coaches managing many athletes because it is easy to unintentionally schedule an important workout, race simulation, long ride, or testing session during a religious observance.

Longer term, this framework could potentially support other faith-based calendars and athlete-specific religious scheduling preferences as well.
