njee whats wko3? free software? does it require the accessories fitted to the garmin to get the intersting readings etc/
Not free sadly, and requires a power meter of some sort.
My Edge 705 will certainly let me have TCX and GPX files - I've saved rides as courses and as routes separately.
Was hoping the 800 could display map and some numbers at the same time, unlike the Dakota. I think it can do this
Pass, as above, I've got a 705, but I'm fairly sure you can have choose a number of data fields to display with the map. If you have a Route it will interupt whatever screen you're on to give you directions, not so with a course.
WKO looks a bit scary (never trained with power before)
It's pretty user friendly, the TSS stuff is good, although if you do a lot of mountain biking you end up guessing a stress score. Garmin are going to do a big power update for the Edge 800 when their Vector power meter comes out, so it'll display more metrics on the head unit. Dunno if it'll work with other power meters though.
