Support

Endurance by Design is built by a small team of people who train for the same races you do. We don't have a call center or a chatbot maze — when something isn't working, or the plan doesn't feel right, or you just have a question, you email us and we answer.

Email us at support@endurancebydesign.com. We read everything and usually reply within one business day. If your race is this weekend, put "race week" in the subject line and we'll get to you first.

Help us help you faster

For bugs or sync issues, two details save a round of back-and-forth: what you expected to happen, and roughly when it happened. If it involves a watch or a connected account, mention which one (Garmin, Wahoo, Polar, or Apple Watch). The app version in Profile → Settings helps too.

Quick answers

• Manage or cancel your subscription. Subscriptions are handled by Apple: open Settings on your iPhone → your name → Subscriptions, or manage them here. Deleting the app does not cancel a subscription.
• Connect or disconnect a watch. Profile → Connections in the app. Disconnecting stops syncing and removes the connection's stored activity data from our servers.
• Apple Health permissions. iOS Settings → Privacy & Security → Health → Endurance by Design.
• Delete your data or account. You can delete your cloud training data from Profile in the app, or email us to delete your account entirely.
• Something in your plan looks wrong. Tell us — the plan engine is the heart of this app, and reports like yours are how it gets better. Include the workout and the date.

The fine print

Our Privacy Policy covers how we handle your data (short version: your health data is never used for advertising, ever). Our Terms of Service cover everything else.

Thanks for training with us. See you out there — and again tomorrow.
