so i'm diabetic and i'm trying to work out how much food i need to take on board during the bike portion of an ironman. i was out for a ride on saturday and actually felt quite good, so what was meant to be a 100km or so ride turned into a 160km ride. i didnt quite have enuf food on me so i relied on shops along the way. this is what i had to eat during the bike:

2.4l or so of powerade

5 carboshotz (less than i would have had but i wasnt expecting to be out for so long)

4 x snickers bars (seemed to be best thing i could buy along the way for energy)

2 cans of coke

is that quite a bit? or is that about average? because from what i can gather thats about 420 grams of carbohydrates or so. and i still ended up going low in blood sugar aka 'bonking'.
