I should have said that I didn't have gatorade or anything like that. Just water with a little celtic sea salt so it was no calories at all for 2 hours. It was a bit of an experiment anyway so on future long rides I will start eating earlier as I have no intention of using sugary drinks. There too hard on my digestion apart from anything else.
This ride wasn't a bad effort as I was riding a 24" wheeled mountain bike with slicks and a few nice parts.
