What’s your weight and estimated finish time?

I burned 2,250 calories in my last Oly event (with a time of 2:20ish) in conditions that were not bad and almost bonked despite taking in probably 300ish calories (and my same old prerace fueling routine which never failed me before). So I don’t think it’s always as simple as some others have suggested. It made me rethink my strategy and that I may need some more calories before and during.
