I would like to be able to see my running pace easily when tracking a run, which means I need to set pace as field 2 in the display. Field 2 is the only one large enough to see while running. However, I am unable to edit field 2, it says "Field 2 is reserved for the activity timer". How can I fix this issue please? Its exactly the same for display 1 and display 2, which doesn't make any sense. How can this be fixed? According to the manual I should be able to edit field 2. Is my watch faulty?
