To create a Route from an existing Activity:
This can be done from your own activities or someone else's activities. Please note this feature is only available for someone else's activities depending on their privacy settings.
1. From the Strava website, navigate to the Activity page where you'd like to create the Route.
2. Click the "wrench" icon on the left hand side. Select "Create Route"
3. You will be re-directed to the Strava route builder, where Strava will create the Strava Route based on the Activity data.
Keep in mind that this tool is limited to our current basemap. That means that if the original activity does not match Strava's basemap of existing route data then the process will result in an error message.
