Does anyone have experience with doing a tune up race with a Garmin Coaching Plan? I have a 10k race that I was hoping I could test out some of my paces and see how I'm doing fitness wise. But my coaching plan put in a 22k long run at an easy pace. Should I forgo trying to use the 10k as a fitness test and stick to just running it easy and adding an additional 12k after the race? If I just race the 10k will the coaching plan view that as "missing" a run/not completing it?
