I've just measured my KLETS route as: 26km (16miles) with 1800m ascent on day 1, and 20km (12.5miles) with 1500m ascent on day2.
It depends on how accurately I've measured it course, but that's less climb than the planner's estimate - maybe the planner's route was higher level and less contouring. Shorter than the previous 3 years, but with slightly more climb (except compared to the big one from Langdale in 2011).
