I would like to know my total work output (kJ) during a ride. Uploading this with my other 500 data to GC would be useful.
Absolutely!! I don't know why it doesn't show as a data field in Garmin Connect when it's obviously available on the 705 itself. I use this information much more than the flawed calorie computation in the Edge series (e.g., counting calories for all motion, rather than when I am actually applying power via pedaling).
