I'm following a Garmin Coach training plan and have an Easy Long Run to do tomorrow. I wanted to record a 5k parkrun, then do an actual course after to make up the distance of the long run. I wanted to ensure that the Garmin Coach activity records the entire distance. I know I can follow a course as part of the Easy Long Run if I select one before starting the activity as I've done that before, but it seems that you don't have an option to select a course if you've already started the activity. It's only the option to Resume, Save, Discard etc.
Is it a case of starting the course I want to do after the parkrun and just know that the watch will keep telling me I'm off course until after the parkrun has finished? Other than perhaps preplanning the parkrun course to be included in the overall course too?
