When to expect the runner at each aid station. The times spread a 10:20 finish the way the median finisher spread their race over this course, so the climbs and the night take their real share.

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.
