For some reason I was a little low on energy for this  morning's 2-wheel 7-mile commute.  My blood glucose was on the high side of normal when I woke up;  I made my usual 1/2 sandwich for breakfast and pumped the normal amount of insulin to deal with it, and blahhhh.... I was poking along with no zip.  When I got to work the Blood Glucose (BG) was 55, not a good level for cycling exertions. 
Pre-Ride BG: 126            Post-Ride BG:  55
Beginning Battery Voltage: 12.5       Ending Voltage: 12.5   (Gel Cell battery pack, no charge since yesterday's ride)
