I've already done a 10k, but when I select a plan for the half marathon the garmin coach is suggesting me to run first a 10k... Still, it doesn't allow me to select a time goal but only a "complete" goal. In the past, I had started a time goal plan for a half marathon but I couldn't finish it. Now it seems that garmin coach has forgot what I've done or maybe it is because the last plan was some months ago. Anyway, it should care because it doesn't know if I was running without recording the activities... So now I've to continue to train with a "complete" goal, quite annoying.
