    I guess this supported effort by Kilian https://www.strava.com/activities/15776699616 should be here as part of the FKT supported. This is part of his States of Elevation project.

    Nick Fowler completed this section in 1d 11h 46m in his supported pct fkt attempt in June 2025. I believe this is faster than Karel's supported time in 2023.

    Sorry about that, I just messaged to get that fixed, hopefully it now accurately represents the route!
