Blue blocks show how many km I did per 12 hours. The red line is "compensated", minus 10% for "afternoons", and plus 10% for mornings. This is to acknowledge the fact I was only sleeping in the morning. It gives a better image of the actual race pace. Additionnally, yellow and green lines show the theorical average for 800k (just below 500 miles) and 900k. One can see I had to push it to get the 800 mark at the end.
