So now that workouts are included on the 500 I figure I should probably utilize them.

Garmin Training Center doesn't even touch power. I couldn't find anything on Garmin Connect. The only way I found to build workouts on the PC is through a plugin in Sports Tracks (which I otherwise don't use).

So I set my power zones in there, created a workout, and uploaded it to the garmin.

For starters, the intervals in which their is a target for power, on the Garmin it says there is no "target". When I try to edit the workout on the garmin to go to, say, zone 4, the zones are all off (they are very low, so I presume they are just the default zones).

I've tooled around a little in the Garmin to see if I can change the zones in there, but I haven't had any luck. The manual that came with the Garmin is no help (Because it doesn't exist...)
