diabetics on the run

i wonder: has a Type 1 diabetic ever successfully ran and finished a marathon? if so, i imagine they would've been equipped with a pouch filled with sugary delights. i envision the marathon volunteers handing them Gatorades. and that gets me wondering -  did they check their BS (blood sugar) throughout this long adventure? on the 4th mile? in between miles 15 & 16? Cause I know I can walk and check my blood sugar at the same time, but would I be able to run and operate my glucometer simultaneously? eh.

well, diabetic marathoners do exist, FYI. that's inspirational, huh? 

what? marathon? me? most likely not. but, 10 K, here I come. after a few trial and errors with the blood sugar control, of course.
