Has anyone done the 2 day or 3 day walk for breast cancer?

Hi! I am strongly thinking about doing the Avon 2 day walk for Breast Cancer in June. I am wondering if anyone here has done it w/ diabetes, especially those on a pump. I have absolutely no physical endurance…I am ashamed to say I don’t work out. I would like to train for this walk and get myself into better physical shape. Its a win-win situation to me. I am very worried about having low blood sugars and carrying all my supplies. Any advice or words of wisdom will be greatly appreciated!!!
