[QUOTE="notoriousnick, post: 1464531, member: 184562"] A bit late to this thread, but ... I run up to 120km a week. My BGLs will rise quickly after a run. However, a few hours later, BGLs will start dropping as muscles start sucking glucose out of the blood stream to replenish glycogen stores. The initial rise is probably from counter-regulatory hormones (adrenaline, cortisol, etc.) generated during the run. I treat this with insulin in a pre-emptive way. That is, I don't wait for BGLs to go up, I just give a few units shortly after the run is finished and monitor BGLs closely. Once the fast acting insulin has worn off, I keep an eye out for dropping BGLs, as this is when the counter-regulatory effect has also worn off and BGLs may start to drop. The length of time this happens may depend on how far and hard you ran, your fitness and physiological factors specific to you. Stick with it - eventually you get things right by trial and error! :-) Just my two cents. T1D since 1972. [/QUOTE]
