Around 50. With 3 climbs, one half-mile climb onto the plateau, and the two little hills on top, one 250m and the other 225m totaling a good 3/4 miles total climb.
And as if that was not enough, got caught in a cold rain with nasty winds while on the plateau. One 4 mile section really was no fun at all. I think my toes are slowly drying now. And I didn't lose any on the decent either (45 mph in soggy shoes does cause some evaporation cooling...)
Anyway, the grand total:
9646
And now for some carbs.
