Weird blood sugars and what to do

I got up this morning at 5AM for a 4.5 miler with (5X25 sec. 5K pace) hill fartleks included. My blood sugar at 5:05 was 212, not exactly ideal, but it must have been elevated because last night I had consecutive blood sugars of 66 and 61 at 9PM and 9:15PM respectively. I treated the first one with a pack of sport beans (25 grams of carbs) and 15 minutes later my blood sugar was 61. I then pulled out the heavy artillery and swallowed a tube of glutose (15 grams of fast-acting carb). I felt better, did some reading, fell asleep and did not check it again until this morning.

I gave myself 1 unit of insulin via my pump at 5:05 (in retrospect, I probably did not need it) and reduced my basal rate to 50% for 30 minutes during my run. Great run by the way, but my blood sugar was 70 when I returned at 6:20AM.

Lessons learned: 1) I do not need to bolus if my blood sugar is 150-250 before a run; 2) I will continue to reduce my basal rate for runs of 40 minutes or longer, track the results and learn from experience what works best.

Happy running, and check those sugars!
