I have already downloaded the Combo Running Power app, added the 1 layout data field to my watch, and completed a few runs. As I'm running, I'm able to see the run power stats on my watch. However, I'd like to be able to set my run power zones on the watch. I followed the instructions from Garmin on how to set the zones, but there is no 'Run' zone category for me to customize, nor is there a way for me to add it - see screenshot below. I only have Cycling and Cross Country Skiing. What do I need to do in order for Run power zones to be setup?
