[QUOTE="Neximus, post: 1762987, member: 89653"] Managing Type 1 diabetes and exercise is not simple but it is perfectly possible to deal with. I’ve had frustrating times but managed to get round them. I do a lot of road cycling and tend to ride 3 days a week covering a total distance of around 100 miles pw. I rarely have hypos or hypers when riding but that is down to planning and experience (and things have gone horribly wrong a few times!). I am currently using a medtronic 640G insulin pump. My strategy is to eat at least 2 hours before exercise and I reduce my bolus by 20%. I also reduce my basal rate by 50% 2 hours before I set off. By the time I start my rides I have some (but not a lot) active insulin in my system. This is vital because it avoids hypos. But it is important to have “some” background insulin. I always take far too many sugar gels with me (to keep my mind at rest!) and I keep well hydrated. If I have got it right I use no more gels than a non type 1 cyclist but I tend to need more to keep my sugars safe. I BG test on my rides every half hour or so. I’d love a Freestyle Libre but can’t afford and GP won’t prescribe. My cycling friends don’t mind stopping and I think they’re pleased for the rest! My biggest ride is the Prudential London Surrey 100 miles which I completed in 5hrs 38 mins. I have also cycled abroad in significant heat (40c) but have kept BGs in range. I am simply saying that whilst it is difficult to exercise as a Type 1 it is not impossible. We are all different and some simply can’t do it and stay in range but I do think that for most of us it can be done with a bit of planning. I have used injections for most of my life and when I had a long acting and short acting insulin I cut my long acting by 50% on riding days and reduced short acting before exercise by at least 10%. I hope that is useful. [/QUOTE]
