Wednesday I'm riding to Jeff City, which is 30 miles away, because I need to get there and I don't have a car available to me that day. All of which makes it an excuse for the ride. And then 30 miles back. So I will be able to test the sugar thing on a ride of a decent length.

Most of my rides are shorter, in town commutes, and of course I'm not trying to ride well or fast, just get there. It could be that when I go on my long trip, I will go ahead and start eating sugar again. But I hope not.

I know that exercise attenuates the sugar high and therefore the crash. It's more a mental thing: if I allow sugar on a bike ride, other excuses creep in!
