on of Rock's squash
we love that stuff - I like the orange best. Tastes great when you're cycling. I have a large bowl of porridge before I go out for a long ride. A flapjack or two during.
I tend not to drink much on a ride for some reason, but make up for it afterwards. Have never bonked when using the above method, but as said before - everybody's different. I have bonked in the early days when I didn't have enough to sustain me. It's not nice.
