Hi,
Bug detected: there is a multisport activity but there is no way you can create workouts for it, because the watch only allows you to upload workouts from garmin connect and garmin connect does not allow you to create multisport workouts!
I have very recently bought Forerunner 945 and terribly disappointed with it. Main reason: I cannot create MY workouts on the watch. I have an ab and cardio workout with excercises placed in multiple categories on garmin connect. Right now on this 500 EUR watch there is no way to record this plan of excercises with the time alotted for each excercise into one work out.
