When to expect the runner at each aid station. The times spread a 8:35 finish the way the median finisher spread their race over this course, so the climbs and the night take their real share.

| Isenau Station Retourkm 22.6 | 3:28 |

| L'Etivaz (arrivée)km 51.0 | 8:35 |
A gap grows with the hours. A runner 20 minutes behind these times at halfway, holding the same pace, will be about 40 minutes behind at the finish, so push the later times back as you go.
