Changing the workout?

Is there a way to switch the run workout in the watch?

I am currently training for a half marathon using Runna. Most of the time the training runs are synched and there is not an issue. This morning during my “wake up” report the Runna planned run was there. When I went to start my run, the suggested run was not the Runna planned run, it was instead a base run suggested run. Is there a way to reconnect/sync the Runna planned run? I ended up using the app on my phone for the pace cues and just started a run on the watch. I wouldn’t mind that if the GPS matched up, but it’s usually faster on my phone. I was at .98 on my garmin when the phone said I hit the first mile.
