[QUOTE="valleyboy, post: 615653, member: 110836"] Hi there Lambey, I hope the running and cricket is going well. I've just read your travails at getting your blood sugars consistant. I think I would echo a lot of the other comments. It really comes down to testing, testing and more testing. I am still in the honeymoon stage but have learnt so much in the last 11 months. From being diagnosed one day after running a marathon last October and thinking that was it for running and triathlons I have built up a list of things that have worked and those that havn't. I certainly have loads to learn and every day is a learning experience but I have gradually gone from doing 1K on a treadmill back to doing open water triathlons and longer runs. All I can say is there are loads of variables that seem to have an affect. Temperature, intensity, nerves, tiredness..... From what you say you have a good handle on things. Things that I have found to have helped though include the following:- - keeping the same level of insulin but avoid training within two hours of taking fast acting insulin as the effect can be quite dramatic in lowering blood sugars if exercising withing two hours - I was also having highish readings all afternoon but now try and keep fairly steady blood sugars 2-3 hours after lunch and before I exercise. If blood sugars are a bit on the low side ie 4-6 then I will eat extra carbs 20 minutes before I train. - usually for a 5K run I would aim to start at a minimum blood sugar value of 6-6.5 - generally a 20-30 minute steady run should not need to much if any extra carbs - Often I will take a 20g longer lasting (ie banana/ceral bar) and a quick swig of lucozade prior to a longer run or if the levels are around 6 and it's a long time since lunch - I usually take a bottle of Lucozade with me and sip that and for a 5K or 10K this should be enough to keep level maintained. However I am on a relativley low basal figure so this will change I am sure in time. When I was initially on higher levels I was finding that after 25-30 minutes running I would take approx 1 jelly baby (4grammes) per mile seemed - this seemed to suffice for anything up to half marathon distance. - The type of exercise will have an affect - I live in the hills of North Wales and run a lot in the hills of Wales and Cheshire so a lot of the exercise is anaerobic ie not enough oxygen getting into the muscles and the incomplete breakdown of glucose means blood sugars will rise.
