Connecting Strava lets you do two things: import your Strava running activities into Arc's log (so they count toward Running Ranks), and post your Arc strength workouts to your Strava profile after completing a session.
How to Connect
Open Arc and tap the Planning tab.
Scroll down and tap Strava.
Tap Connect with Strava and log in to your Strava account.
Select the authorization options (read activities, upload activities) and tap Authorize.
Your recent Strava running activities will appear in your Arc log within a few seconds.
What Data Flows Where
Strava to Arc: Arc imports your running activities from Strava, including distance, duration, and pace. These runs appear in your workout log and count toward your Running Ranks across the mile, 5K, 10K, half marathon, and marathon. Arc only imports running activities, not cycling, swimming, or other Strava activity types.
Arc to Strava: After completing a strength workout in Arc, you can post it to your Strava profile. The post includes the workout name, duration, and exercises performed. This is optional and happens per-workout, not automatically.
Import Limitations
Arc can only import the last 30 days of running history from Strava when you first connect. Older runs won't appear. Any new Strava runs recorded after connecting will sync automatically going forward.
Strava vs. Apple Health
You can connect both Strava and Apple Health to Arc at the same time. If you do, Arc deduplicates runs so the same activity isn't counted twice.
Use Apple Health if you record runs with an Apple Watch, Nike Run Club, or any app that writes to HealthKit. Apple Health syncs happen on-device, so they're fast and reliable.
Use Strava if Strava is your primary running tracker, especially if you use a Garmin, Coros, or other non-Apple device that syncs to Strava but not directly to Apple Health.
Use both if you want maximum coverage. Arc handles the deduplication automatically.
Posting Workouts to Strava
After completing a strength workout in Arc, you'll see an option to share to Strava on the workout completion screen. Tap it to post the workout summary as a "Weight Training" activity on your Strava profile. This is a one-tap action per workout. You can skip it if you prefer.
Activity Visibility
For Arc to import your Strava runs, your activity visibility settings in Strava must allow it. If activities are set to "Only You" in Strava's privacy settings, Arc may not be able to read them. Set activities to at least "Followers" or "Everyone" visibility.
Troubleshooting
Strava runs aren't showing in Arc:
Go to Planning > Strava in Arc and disconnect.
Reconnect by following the setup steps above.
Check that your Strava activities have at least "Followers" visibility.
Wait a moment after reconnecting. Sync can take a few seconds.
Only recent runs imported: Arc pulls the last 30 days of history. Older runs won't appear, but all future runs will sync automatically.
Duplicate runs appearing: If you see the same run twice, you likely have both Apple Health and Strava syncing the same activity. Arc deduplicates automatically in most cases. If duplicates persist, try disconnecting one source and using the other.
Strava says "authorization expired": Reconnect from Planning > Strava in Arc. Strava tokens expire periodically and need to be refreshed.
