That's a *VAST* amount of endurance exercise. Running a marathon can
easily take around 3500 calories so less than what you burned.

I see now that my guess of 4,000 was rather optimistic. It was probably
something around 2,100 and it was from 33 miles of cycling (230 lbs @
15mph = 966kcal/hour x 2.2hrs = 2125)

You started out low carbing but not ketogenic low carbing, right? That
means you started out with a smaller glycogen store than low fatters or
carb loaders. The rest still adds up to you running through your
glycogen stores and going into ketosis. Beneficial.
