Just a quick post to say that I was given one of the new Garmin Forerunner 610 watches to review and have posted my first impressions on my blog.
In summary, once you get used to the touch screen interface the watch is much easier to navigate then the old FR 405 and 410 models and can be operated without any problems when either wearing gloves or when it is raining.
I tested the forerunner last weekend during a Half IronMan triathlon that I took part in and really like the way that you can switch between running and cycling mode with one click of a button. During the race I relied heavily on the the distance alerts to remind me when I needed to take on nutrition and also tied it into my bike cadence sensor to make sure that I want exerting my legs to much before the run section of the race.
The watch is very quick to lock onto a GPS signal and the figures that are reported seem match up to the other Forerunners that I have run with, so no problems there. There is a bug in the current firmware release that causes the GPS accuracy to fall when you use lap/split, but hopefully Garmin will be releasing a fix to this soon.
