A cycling desk / Zwifting with a split keyboard

This is madness. But having said that, I might try to do the same.

This is madness. I will never try this!

That may be, but you know that in order to truly one-up him and show your dedication you're going to have to do it on rollers.

Same, I don't understand zwift, nor do I understand using a trainer outside of warming up before a time trial, xc or cyclocross race context.

The whole fun of cycling is to actually ride a bicycle, feel the wind, the road texture, notice the changing seasons in the landscape, rail corners at high speed...trainers annihilate all this and reduce this nice and enjoyable activity to a boring and terrible fitness activity. No screen would change that.

I think the idea is: if you have to work anyway, you might as well get some huge Z1/2 volume in while you're working. Most of us with regular 9-5 jobs don't usually have time for the 25-35 hour training weeks that full-time pros sometimes do.

I agree- utterly insane. He should be using Emacs.
