Build a race-specific plan
Weather is optional training context, configured under Runner Profile. Weather adds context to reviews. Plans are grounded in your training history, not a single weather forecast.
Version 1.1 begins at your current comfortable mileage, then progressively builds toward your race with easier recovery weeks, rest days, and a race-specific taper. Your starting mileage is not a lifetime ceiling. These are coaching heuristics, not a validated individual prescription. Update your preferences and regenerate your schedule when you want. Regenerating changes only the selected plan. Other saved plans are not changed. Export a backup first.

Training trends
Your training history
Switch between this plan and all saved plans. Trends use completed sessions and are not a medical evaluation. Similar pace and HR on comparable routes can help provide context, but do not prove aerobic improvement.

Cloud sync requires internet. Keep a backup if your data matters: Plan Settings → Download full backup. If you switch accounts on the same device, each account gets separate local storage.
Runner profile & heart-rate zones
Optional details help estimate training zones and energy use. You can leave these blank, and edit them at any time. These estimates are not medical assessments.
Weather and location preferences
Optional training context. Use your location on demand or choose a city for local forecasts. Mile Zero can reference recent conditions during training reviews. Your exact GPS coordinates are not saved to your runner profile or sent to Supabase. Coordinates are sent to the weather provider when you request a forecast.
Saved training location (optional)
Save a city or town, not your address. The city name is part of your account profile and syncs to your private Supabase record. Weather is fetched from the provider only when you request it or request a training review. No precise GPS position is saved. You can remove this anytime.
Weather forecasts are not a guarantee of safety. Heat, humidity, wind, air quality, personal health and effort all matter. Weather context may inform a training review, but it never automatically edits your schedule. Weather by Open-Meteo (CC BY 4.0). Free API for non-commercial prototypes only.
