Cheers for the replies.
The energy drink I use says is also has electrolytes in it, so this shouldnt be the issue I dont think.
Yesterdays ride, just over 30km, took about 2 1/2 hours moving time, and I drank just under 2 1/2 litres liquid. I have always drank a fair amount of water.
It could be my position and i’ll look to work on this, but I have a couple of bikes, and recently changed full bikes too and have cramp on all of them.
Thanks for the link Jonba, I had come across it on my search for possible cures. It basically says that fluid and water/electrlyte intake are only part of the answer but fitness and pushing beyond your limits are probably the main reason. Im guessing it’s down to fitness in general as I really only get a chance to ride fortnightly, with the ocassional evening ride of around 10km here and there.

Pete
