So I am totally weird about the "goo" type things...I can't eat gluten and have all other gut and bladder issues, plus process things WAY different than most people. It's funny...I can do real food, even real sort of unhealthy food like butter and sugar, way better than I can any processed stuff. Plus I have a texture thing and some of those goos make me gag. That said, I have found some great foodies for when I run.
I use honey packs like you get at Smart and Final; individualized honey packets. I also use the solo packs of Justin's Peanut Butter and Honey and Almond Butter Chocolate. I love marshmallows and these are a quick sugar boost as well as Swedish Fish and Starburst (reds). I also mash up a banana in a zip lock, bit off the tip and squeeze in mouth.
The other thing I use are the veggie and fruit mashed packs that originated for kiddos but now they have for adults. Some good ones are Peter Rabbit Organics, Organic Mash Ups and Go Go Squeeze. I like Happy Squeeze too but it has added fiber. Not so hot for runners.
I use True Lemon powdered drink mixes...kind of like the other brands but natural. And of course water. For races, I do drink Gatorade but normally not as I hate the after taste.
I could also totally eat a peanut butter and jelly sammie on the road too. That would be great as long as you have water.
Speaking of water, LOVING my Nathan female friendly (for woman) water pack/hydration pack. I don't even feel it and I have all my goodies right there.
