Perhaps it is just CA, although Breathless Agony has 4 distinct climbs and Everest Challenge like a hundred. The profiles are almost always deceiving, though. The uphill for the first 25 miles is more rolling than anything, with only like a 1% grade in between the rollers. The first peak is a challenge, though: it has a 125-yard wall at the top of like 10-12% or so.
