Common questions and troubleshooting.

Adjust this week without losing the contract

1. Open Week and tap Adjust week.The current week opens with its mileage contract and the planned work still visible.
2. Select the workout’s original day.Long-press the workout and drag it down to Unscheduled. The complete session moves with it.
3. Select the new day.Long-press the workout in Unscheduled and drag it up onto that day. Moving it changes the calendar, not the workout.
4. Tap a workout when the session itself needs to change.Edit its distance, type, title, notes, warmup, repeats, recoveries, and targets.
5. Check the week, then save.The contract summary shows the resulting mileage, quality, and long-run shape before anything changes.

Hand a complete plan to another runner

1. Open Plan, then open the plan’s options.Choose Export .due. Due turns the installed block—including your edits—back into one portable plan file.
2. Send the file.Use Messages, Mail, AirDrop, or save it to Files. The file does not include your personal calendar dates or completed runs. It can include notes attached to workout days, including notes personalized for you, so review those before sharing.
3. The recipient opens it on their iPhone.Tapping the .due file opens the complete block in Due for review.
4. They choose their own dates.The runner anchors the plan to a start or race date, checks every week, and installs it as their own block.

Bring your own plan

Copy the complete Due plan prompt →

1. In Due, open Plan → Your plan.Tap Copy the prompt. Copy all of it—the instructions are intentionally detailed.
2. Paste the prompt into your AI assistant.Use ChatGPT, Claude, or Gemini. Paste your existing plan below it, or answer the assistant’s questions if you need a plan built.
3. Bring back the answer.Open or share the returned .due file into Due. You can also paste the returned text inside the import screen.
4. Review the whole block.Due checks the file, shows any questions or warnings, and asks for your start or race date before installation.

Connect Strava

Due asks for read access when you connect. Completed runs sync into the matching week. Posting Due’s week receipt back to a Strava activity is optional, off by default, and asks for write access separately.

1. Open You → Strava.Choose Connect with Strava and approve activity read access.
2. Return to Due.Your recent runs sync against the active plan.
3. Pull down on Week to retry.A manual refresh performs a fuller check when an upload arrived late.
