No crew access on course: what you carry has to last from one aid station to the next.
A barrier is a cut-off to clear, not a pace to aim for: race on effort, and expect the later legs to be slower.
Fuel by the hour, not by the kilometre - each leg is time between aid stations. Race on the fuel you trained with: nothing new this week.
