Turbo Trainer Advice

Yes. Your about right.

But just go what you can for an hour on the turbo don't worry too much, any good training is adaption. And try ride at a higer candece, 60rpm is too low for extended climbing. 90rpm is the equilibrium match between aerobic capacity and leg strength.

When climibing that hill in life, use a bigger rear sprocket so your at at least 80. Grinding away at 60rpm is going to fatigue your legs more than ideal. Get an 11-28.

Done it twice in 41:26 fixed, at a cadennce of 50rpm.

Blacked out at the top the first time, and experianced, intensly painful, total leg cramp 2km from the top the second time.

I'll redo the calc with a better ratio.
