<<Disclaimer: Verify this information before applying it to your situation.>> Tom, I gather you're looking for protein? We used to ride a lot (Canada-Mexico on Hwy1, Scotland, NE US) and we relied heavily on nuts for protein. We'd keep a bag of peanuts as well as carbohydrates in the handlebar bag and dip in as needed. Another protein source which you need to recheck to make sure formula's haven't changed is Oberto Peppered Jerky. It was gluten free a year ago and I keep it in our earthquake kit since it has a shelf-life of probably 100 years! Another option is granola--Make your own substituting crushed sliced almonds for the oatmeal in most recipes. I've done this with our favorite cashew granola and it's quite good. I've also substituted puffed rice for the oatmeal in the recipe. A final option are Health Valley's brown rice granola bars. I've spoken with the company and these are GF. They have a tropical fruit flavor that is outstanding. They come prepackaged, 4 to a box. I keep them in my car for emergency eating. Hope this helps. I know from experience that when you're burning 5-7000 calories a day you need more than a rice cake to munch on!!!! Vicki Pacific NorthWET
