I took my new bike out for its' first ride today. Some friends and I rode 23 miles through historic Lexington/Concord/Bedford and finished at Bertucci's for a lunch of salad and pasta. With the pump I was able to set a temp basal and managed to maintain my blood sugar between 100-150 throughout the ride. I can't even begin to say how happy this makes me. I fashioned a pretty good bike mount for my dexcom receiver so it was easy to see where my blood sugar was and where it was heading at any time.
