I'm assuming this feature isn't currently implemented, despite it being possible to rename the fields in GTC. However, when using the FR610, the original(/default) pace/speed zone names are displayed. Because I think of the zones differently (e.g., low aerobic, moderate aerobic, threshold, etc.) I have to remember which zone corresponds to which by its default name (slow walk, slow jog, etc) which is a pain. It'd be nice even to be able to display the pace/speed zone number rather than the default name.
Seems like this would be easy to implement, so puh-leeeeease do so :)
