Ok, this Cannonball run is an example of extreme
distance riding, so the normal touring rules or experience don't really apply here.
You've done 900+ mile days? Good on you, that's something to be proud of (if that was your goal). But let's do the math here:
2,828 miles in 38:49 averages out to 72.88 mph. That multiplies out to 1,749 miles in 24 hours, almost double a "normal" 900-mile day. Do that again for another half-day, without stopping, and you're still not quite there.
Now I haven't done a 1,750-mile day myself, mostly because I actually value my license.
But I have done dozens of 1,500+ mile days, and a few that were 1,600+. All of which can be done on US Interstates by following the basic speed rules, with maybe 5-10 over (which is less than the flow of traffic in many large cities). No need for 100+ mph jaunts (fun as they may be).
Note that such times include all stops for fuel, tires, and anything else. Do you think he slept? Of course not, he'd just push on through the night, and count on the next daylight to carry him through (that, and the justified paranoia that comes with running 100+ mph through multiple time zones and innumerable law enforcement jurisdictions).
Do you think that just maybe, in extreme circumstances such as this, you could hold your morning constitutional for one day? I don't know if this guy used a catheter or just hung it out on the side of the road (moving or not), but even the occasional pee can be done rather quickly when time is of the utmost importance. And I imagine he made good use of whatever time it took to get that tire changed out . . .
Again, this is an extreme situation, so extreme measures were taken. Not that I'm condoning his actions; I'm merely pointing out how such a thing could
And as I've said before, while I know that my skill set makes me fully able to meet or even exceed his time (I wouldn't be stopping for tire changes, for one thing), my experience tells me that crossing four time zones at super-legal speeds simply isn't worth the risk/reward scenario, much less some random bragging rights.
But you can be dämn sure that I've already planned out just how to do so, purely as an educational exercise, of course . . .
