Best long run fuel product

Wow! Thanks for all the ideas. I can't even imagine being able to eat a banana or a sandwich at this point -- I'm only 6 months out. My pouch is really not sensitive and I did find that a few of the companies will send free samples. Clif and Gu have shipped already.

I'll let you know how they compare for me!

 after the marathon, they had chicken soup.  I thought there is no way I would want to eat chicken soup after running 26 miles, but I gotta tell you, it was soooo good.  I guess the saltiness and just something in there was so nice.  Or maybe just in my head I realized I had just burned off 5k calories and could eat anything I wanted (truth be known, after the race, I at my first chocolate bar in 15 months!! :)  )
