You can connect to Strava such that it automatically downloads your activities.
The Strava API has rather strict rate limiting. If you don't mind waiting a bit, you can just use the "client ID" and "client secret" that are provided to use a pre-defined Strava app. In that case, just click on the button. If you don't want to share the API limits with other people, go the Strava API page and create your own app. Then fill in "client ID" and "client secret" in the form.
For more information about how to use this feature see this page in the documentation For initial import of activities consider importing a Strava Archive.
