Nike+ Sportwatch. Can it do what I need?

DarthH8

Yeeeeeeeeeeaaah. Picked up my Nike+ Sportwatch GPS today. I'm having doubts so far, but I really do like the watch.

Strength Training
So a couple things about it right from the start, it is for running. I didn't quite understand that before I got it, I figured it had the features I needed and I wanted the Apple ease of use. I'm hoping I wasn't wrong about it having those features. I definitely need the HRM strap from Polar to go with it since one of the main things I need this for is to figure out what I'm burning during my strength training. I just forgot to grab it when I picked it up today haha.

Running
I've been a runner for a really long time now and I switched to strength training recently. But since I have the watch it seems it's time to get back into running again. This is what it does best.

Montain Biking
So it seems like this was a poor choice for mountain biking so far... I'm a little sad about that. I'm finding things that say they added MPH readings so at least you can kind of track it. But I was really hoping for elevation readings and all that good stuff, it doesn't seem like it does that so far but I haven't even looked at the interface after a workout so I have no clue.

I think if I use it right it can definitely help me with the 3 things I need it for, but we shall see after I do each of the workouts and look at the data.
