Thanks to everyone for all the great info, I checked out the website for Team Type 1 - it was really fabulous. I did read that they check their BG levels 18 - 25 times during the day... I find that I don't eat enough during the ride and probably not enough fluids either. I hit the wall "bonk", and have no energy in my legs. I can't wait to check my levels while riding - I'm hoping that it will be very helpful.
