What does every hour look like?

The clock times assume a 09:15 start. After 22:00 the plan eases carbs and fluids, because appetite and thirst drop in the dark.

The table stops at the last full hour. The final 30 minutes follow the same pattern.

What to carry between aid stations?

The legs use the average pace of the whole race, so the climbs take longer and the descents less than shown. The stations and distances are approximate: use the race's own guide for the exact ones.
