I tried an experiment on a long distance race this last weekend - a baby food manufacturer has started selling pureed banana (no added nasties at all, just fruit) in a squeezable sachet almost identical to energy gel packaging. So I bought a couple from Tesco and tried them out. Worked a treat. Whipped them out of the hip pocket, squeezed them down, no need for peeling, chewing etc. Highly recommended, if a little unorthodox and a bit embarassing to write about on here
