Query: Good for cycling and running!

I love this watch. I use it for running and cycling (I bought the cadence sensor). My only complaint would be that its only water resistant, not waterproof because I'd like to get into swimming, but will need to get the 310 or 910 if I want to do that. I used it for the Pelotonia (180 mile ride over two days), and the battery lasted for the whole thing! I was impressed!
