Hi Joao,
Thanks for writing in and sorry for the activity syncing troubles. Garmin recently updated which activity types are synced to Strava.
The Garmin Connect developer API program has been aligned to its original health and wellness intent to focus on health, wellness and primary sports (run, walk, bike, etc.) The change to non-primary sports activities such as flying, motorsports, horseback riding, RC drone, etc. means that you will need to export those activities from your device and manually upload them to Strava.
The best option at this time is to
export the original from Garmin Connect and upload it to Strava from our
upload page. Let me know if you have any questions.
Best,
Jimi

As per my reply to the Strava Support Team, the best option for me it to create an activity which I name "Horse riding", it will have sport = "Generic" in the fit file and synchronizes perfectly with Strava (I tested this already) having all the infos of the activity.
