How to capture GPS tracking on GoPro

HI all, I'm sure this is a stupid newbe questions.  

If I'm out on a moutain bike ride for 2 hours and want the GPS to track my location, do I turn on the goPro ( with GPS enabled) and just leave it on?  When wanting to capture video just press the Record button on and off through the ride?  I believe the Auto Time off is set to 15 min.  Is that going to kill my tracking or should I bump that up to 2 hours?  If so, I can't see the battery lasting that long regardless if my recording is probably minimal.  Am I being unrealistic in my wants :-)
