yep this happens a lot and can be a pain in the ass. When racing, you can add adrenaline to the list and all of a sudden your blood sugar skyrockets. You have to be careful not to get too high. Some people can race upwards of 13mmols, but i find i really become lethargic above 11ish. Sprint distance racing you may not need much carbs.



Took the dexcom out again today on an easy ride. Started at 10mmols and spent 20mins in an upper tempo type of pace and i checked my meter and it said 4 mmols (tail end of insulin still on board) where the dex had 6.4mmol and dropping. I can forgive that due to lag obviously. Later on though im treating a 3.8mmols (glucometer reading) where dex says im 7.4 and rising. I envy the people who this device actually works for and race with. Day 2 for my trial, and its still shithouse
