I regularly use Garmin Connect on the web to look over performance stats for important cycling workouts. I will usually overlay power on an elevation plot and check 1 minute, 5 minute, etc. average power numbers and then use the cursor function to look at detailed power vs. elevation data over time. This has worked well for as long as I can remember. Today, when checking my latest workout, the power overlaid with elevation plot displayed just fine, but the cursor on plot function always displayed "0 watts." Is there a simple fix for this? I am using a Garmin Edge 520 plus for my cycling workouts.
