you'd need a hell of a lot of stamina to get anywhere near close to the top. i got to the first corner in about 3 dabs and was completely ****, and i consider myself a half decent climber. maybe with the right bike (not 36lb 6" FS) and in broad daylight i'd get around that corner but you've still got a loooong way to go even from there. you can clear the first stepped section after the gate by sticking tight to the corner and taking the line to the left where there is an eroded cut away section but once you summit there you've landed in the thick of it and would have to power your way straight up and over the next section, the bit where there is a definite smoother section that has been laid that zig-zags around the bigger jagged stuff. clear that and you've got a relitively easy section to recoup before the cobbles, which again you'd need high rpms to keep your momentum up – a tough section after what you would have just done. into the gorge bit with a couple of step-ups(which i cleared last night so they can be done) and you're home free. king of the mountain.
can it be done? possibly. if you're of superhuman qualities. but worth a shot just to see how much of it you can ride. i'd love to see someone do it.
descending in the dark is highly recommended though 😀
