I did about 2 miles today with the dog. I got a Polar RS800CX Multi (just means it comes with the HRM, GPS, and software, really) for xmas from my husband and it was my inaugural run with it all on. I did a 45 minute ride last night with it on, too, but there's no point to wearing the GPS on the trainer.

It was cool to see the route on the map (and how it is downhill at the start and uphill or flat the rest of the way, basically ) and line the speed up with the heart rate chart. Since I had my dog, it was quite comical to actually SEE where she stopped to do her business along the route. The GPS unit is comfortable (it's separate from the wrist unit, which will be quite useful on longer rides and runs and races to extend the lifetime of the most important part, the HRM).

Oops, ETA, this is week 1 of Ironman training. Not really "training" this week, but getting used to daily workouts, sometimes more than one per day, again.
