Welcome to the Forum!
Read through the first three threads in the Type 2 Section, when you get a chance, if you have not already done so. Although these threads are geared towards T2, they are pretty much for any one with diabetes and will most-likely help you a lot. Self education is one of the keys to successful management of your diabetes, along with a healthy sensible diet and exercise. Basically, diabetes requires a life-style change for the better.
Read through some of the posts by username type1rachelle. Her take on food for T1's may help you a lot and she is a runner as well. Good luck with your control and management.
