I was excited to see today, that now in GarminConnect all of the Steps (WU, intervals, rest, CD) from Athletica training plans are now being displayed. Before it would just reference that they were coming from a third party and to visit the site for changes. Thank you Athletica.
I will make an addendum. The workout steps only appear to display in the GarminConnect mobile app. For tablet and desktop computers it does not. It still directs you to view details and edit on Athletica.
