I ran a half marathon on Sunday morning. During the race itself my sugars were constantly dropping so I was consuming around 8-12g of carbs every 15 mins or so and cruised along in the 4mmol range. After the race I remained stable but then for the rest of the day and yesterday my sugars were all over the place; mainly insanely high and not responding to my bolus injections as they usually would.
For example, I had a burger and fries on the evening of the race (the race was early in the morning) and this meal would usually be in the region of 6 to 8 units of NovoRapid for me (at a push); however I needed 12 units and still stayed high (i.e. 12mmol) over night. Finally came down to normal levels at 5am-ish after multiple Dexcom high-sugar alarms and subsequent correction doses through the night.
I'm hoping I'm back to "normal" today (so far so good) but any ideas what happened?
I was wondering if the "stress"/cortisol release of the run could be to blame but then my muscles were aching so badly all day I'd have thought they'd be sucking up the glucose. Last time I ran a half I was fighting off lows!
