hi rainbowchild
here's the regime i use when training :
I'm on Novarapid and humulin I. If cycling to work, 10 miles each way I won't have any carbs or insulin for the morning commute. Usually blood glucose about 6.0 in the morning and i can manage the 10miles ok. I will take 12units humulin I after getting to work. If my lunchtime workout is cardio I'll use 85g CHO per hour with no novarapid. This usually leaves me in range mid-afternoon following a lunch snack where I use a ratio of 1:25g for novarapid to CHO's. Cycle home needs about 60g CHO. (This comes from requiring 85g per hour CHO as I'm 85kg, so about 60 for a 40min cycle). Usually ok prior to dinner meal but always wary of post exercise hypos. Next humulin I at 7pm and generally about 5-7m/mol before bed. I use the same ratios etc for track cycling and can usually manage a 60min early morning track session with no carbos....wake up hormones/dawn phenomenon etc?? There are always so many components to good control, individual and environment and for me it's been about collecting the best information then trial and error. I'm male, 56 yrs old and been type 1 since Jan 2007. Happy to share info if its helps.
