First, thanks for the blessing and 'cause I already rode this morning.

Sure sounds like you're working very hard. I know, for sure I'd never be able to maintain getting 4 hours of sleep multiple nights/week.

It also sure sounds like you're a far more capable rider than I am, so feel free to toss this suggestion out the window.

I'm fortunate to have two bikes, one with electronics and one without. The stripped down, no frills bike gets the nod for rides on a 4 to 1 ratio. It's care-free, I'm not slaving to attain any goal other than enjoying my ride that day. I ride until it's not fun, until I've thought out all those things on my mind, or until I feel guilty about being gone for so long. Usually I'm out much longer on the no frills bike, and when I hit the driveway at the end, I'm refreshed and not exhausted having to meet numerical expectations.I feel like I did when I rode as a kid.

Just a thought. Hope your concerns subside.
