Ok, so, secret, me and disney, whenever I go, there’s exactly one thing I have to have, I have to have a churro. At any cost. On this particular night (the night before my marathon) I was at Epcot, and while I had little to no desire to go "walk around the world" I did walk all the way to Mexico to get a churro.
After much consultation, I decided 60 carbs was a good number to bolus for. We’ll just say that I was close enough and that those churros truly are costly.
