We spend our leisure time to make RUNALYZE as good as possible and we still have tons of great ideas, but time is scarce and after a hard training we first need some fruits or a smoothie. You can support the development of RUNALYZE with every financial contribution — We highly appreciate every grant. https://blog.runalyze.com/donate/
You did everything right.. The official Garmin Sync allows us only to get the latest thirty days of activities.
Look at the Synchronisation Window at RUNALYZE where you connected your Garmin account. You will find the "special tool" which is able to download the complete history into your RUNALYZE account.
