I wonder how much time* testing blood sugar and taking insulin shots adds... especially in the cold?
John Ryan is a type 1 diabetic, which makes any sort-of endurance event WAY more difficult. I know John wouldn't want that factored into his time, but I bet being diabetic probably added a couple hours.
*I actually sorta know the answer, because I'm a Type 1... it adds a LOT of time. And, in cold weather, it's much worse.
