Marc I agree that the RW schedules do not list the 610, but if you check the Garmin website you will see that the 610 is compatible with Garmin Training Centre (GTC). And, GTC is where all of the RW training schedules get pushed for download to the compatible Garmin devices! So, it all works perfectly. I am really happy with the 610. Bottom line is that it has no more capability than the 405, but the way it delivers the capability makes it functionally a much better package. And it looks so much better!
Have had my 610 for around 3 weeks now. It has replaced a 405CX. I have run with it 15 times in conditions ranging from heavy rain to hot & sunny, covering just over 120 miles. The 610 has worked without fault. The display is easy to read, the touch screen is easy to use, and I particularly like the vibration feature, which means I can listen to music while on interval runs.
The watch is much more wearable day to day than the 405. So much so that if I am planning a run at lunch time while in the office, I ditch my Panerai and wear the Garmin all day! Battery life has also been excellent with the watch lasting for a full week on a charge; and thats with 5 hours plus of training with HR monitor.
I can also download all of the RW training plans from Garmin Training Centre as with the 405.
