Can you keep certain app active in background during sleep?

Can you keep certain app active in background during sleep? I'm trying to use my TP2 to track my driving/hiking trips so that I can later geotag my pictures that I take along the way and upload the pictures with the GPS-tracked route, using a website like everytrail.com.

The problem is, when TP2 goes to sleep to save power, it appears that my GPS-tracking app stops working as well. Is there any way to keep the GPS-tracking app active even when the mobile phone is asleep? Or do I have to keep the phone on during the whole time? If the latter, my cell phone battery won't last longer than a few hours' continuous use, greatly diminishing my intention to use TP2 as a GPS tracker during a long trip.

you mean, can you turn the backlight off and keep the app running?? lol

Or you can just get a power cable/adapter for your car and leave it on during the whole trip.
I usually run my GPS along with Slacker for long trips and the phone is on the entire time.
Also if you are hiking more than a few hours... You make me sick. LOL.

I use several apps for tracking my mountain bike rides and none ever has a problem of running when the phone goes to sleep.

Which tracking app do you use?

I've only used run gps trainer and it did not have this issue either.

Mostly, I use Runsat, but I also use GPSCycleComputer, Endomondo, SmartRunner, GPS Sport Tracker, and Bike Dashboard. All work fine in sleep mode.
