It makes sense to an extend. Being at 9000 feet, the "Marathon effort" is obviously much slower than 4:45 and therefore the impact on his legs.
The impact on the cardiovascular system on the other hand would be identical than a Marathon.
This, in my opinion is mostly psychological ("burn out"). So if he is able to handle it, ok...
We'll see on Monday.
4:45 sea level is worth about 5:10 at 9000'. Definitely less abuse on the legs. Not exactly identical on the cardiovascular system, otherwise there'd be no point in training at altitude; it's tougher on the cardiovascular system.
Psychological "burn out" is very closely related to nervous system exhaustion.
I think Ryan will have a good run, but will never be in contention for the win because he'll let a gap open up immediately and just run at his own pace. Or at least that's what he's always seemed to have done in the past. That loses him about 2:00-2:30 over the course of the marathon, assuming those he could run in a pack with didn't completely fry him up. That's the risk you have take with the marathon, though. If you want to win, you have to go all in and run with the front group. If you can't do that, the best hope is to play it safe and hope for 2nd or 3rd at best.
I would be so pumped if Ryan won Boston. In fact, I would go to church the rest of that week and sing praise to Saint Ryan de Gran Oso.
