[QUOTE="Scardoc, post: 289003, member: 44692"] I find that one of the key things that determine how I cope with exercise is whether my BG levels are rising or falling beforehand. I always use jelly babies to keep my sugar levels up during running and, unless there's a specific reason (such as having excess sugar beforehand to increase my BG levels to be able to run!), my BG levels always fall and I need to eat afterwards to prevent them falling further. I used to (on doc's advise) keep my BG level high (8-10) but have stopped doing this as I was ending up having readings of 12-14 before exercise. The exercise brings it down nicely but I was worried about the effects it was having in the interim. I am now comfortable going for a run when my bloods are over 5 and I adjust the number of jelly babies to suit. Intense exercise, especially interval training, needs extra sugar. However, I have a question. I tend to find that if I am running a 10K and I take a jelly baby every mile, then when I get to mile 5 I normally end up spitting it back out. I can't explain why but it's almost as if my body is telling me I don't need it. I am not sure if this could be the result of counter regulatory hormones. Anyone else experienced this? [/QUOTE]
