I have created a datafield, based on my Datarun-datafield: https://apps.garmin.com/en-US/apps/9...1-da97e59b0d99
Setup: you have to select the running activity and then long press the middle button on the left side. Then a menu opens where you can change the settings of the running activity. You can select the first datafield and change to one single field. Then you must change the contents of that single field, again using the menu. You have to choose the IQ option , then you can choose Datarun.
Don't forget to specify the settings you want, otherwise you get the default settings that I have specified. You can change the settings through the Garmin connect app, but for some people that doesn't work. Connecting to a PC and using Garmin express always works for changing the settings.
You can find the manual here:https://vermail.nl/datarun-plus.
In time I will create a copy of this datafield, so that one can have 2 versions with different settings.
