There is a new running podcast on the street called "The Diabetic Runner." Jamie has been a diabetic for 16 years and a runner for about 1 year. He ran his first marathon at the same time and place as I did (Disney World Marathon in January this year). He has been recently inspired by the running podcasts that are out there and decided to try his hand at making his own.
I think he did a great job, so be sure to give him a listen (and he didn't even pay me to say that).
