How do I import my activities from ASICS Runkeeper?

Export your Runkeeper activities on the web in Runkeeper Settings, then simply upload the file to List Hiker.

ASICS Runkeeper sadly does not allow other services to synchronize recorded activities in an ongoing fashion. One workaround is to simply re-import whenever you wish — List Hiker will only load your new activities. Another is to redundantly track new activities with Strava (or another service, such as Garmin Connect, that syncs with Strava).
