I'll see in the morning - I may try to downgrade my registration to 'senior' so I can start at the hill, rather then the 4km lead up. If so - then I'll run th same as Azami which was a bit too stiff for Azami - but should be fine for Iwaki. If not - then I'll run the lead up in my freewheel (20t) and then swap to the kotei (23t) at the Skyline gate. I lose a minute during the swap - but running the 20t to the top would not work. And running the 23t on the lead up will just be agonizingly slow.
Fantastic, Tim. Well done! :clap::clap::clap:
