I just found this thread, sorry the post is a little late, but I hope my .02 helps.

I've ran in half marathons and the Chicago marathon and always used PowerBar gels. I've tried a couple of other brands, but always come back to the PowerBar gel packs. For me, I like the citrus flavors primarily and switch to other flavors that contain some caffeine during the later part of my distance runs.

I've never had a problem with PowerBar gels, for me they digest fine, but it is a personal preference. My usual rule of thumb is about every 3 miles, I'll use a gel pack with some water.

I also use a fuel belt on distance runs, which gives me a way to carry the gel packs along with 3 bottles of Gatorade and a bottle of water to wash the gels down.

Some guys I work with that do tri-s and Ironman competitions like the Endurox and Accelerade products, but I haven't personally used them.

I use Gatorade Endurance Formula, IMO it's much better than regular Gatorade and I can tell the difference using it on longer runs.

Hope this helps...
