There's lots of info on jet top speeds, but what is hard to figure out is what jets are the fastest once you consider medium and longer length courses.

What is the fastest jet over 500 miles and over a 1000 miles? (No aerial gas ups)

Any current or retired production airframe could be the answer (like F-111) and in ferry configs but let's limit to machines that can carry air to air weapons (no B-58's or Tu-160).

I suspect over longer distances many fighters would lose to a Citation X or G650.

I also bet the answer is quite debatable...

YF-12. Mach 3+ for 3,000nm.

And the G650 is cheating, 0.85M for over 6,000nm or 0.92M for almost 4,000nm.

The F-106 for a fighter that was actually operational (optimum cruise was up at 37,000 plus at 0.9M)
Darn, here I go again gushing 'bout the 6 !!!

Pretty sure it's closer to 2000 miles. Today's fastest over distance is the Mig-31.

While I haven't seen the equivalent data for the YF-12, IIRC the A-12 and SR-71 could both do over 3,000nm at 3.2M, the SR-71 capable of roughly 3,500nm at 3.2M, based on declassified manual pages.

Mig-31, no contest.

Sucker could maintain mach 2.3 if reports are correct, over no small distance...

YF-12 gets disqualified over 2 counts. One, it was never a production piece. Two, It gets aerial refueled pretty soon after takeoff.
A G650 could maintain .95 to .97 over a 1000 miles distance... Citation X could likely do the same for at least 500.

A 106 is a good mention. Maybe it could beat those two over 500 on a .9 cruise climb profile and then save some fuel and altitude for the last 50 to 100 supersonic. Anybody know the fuel flow rate for a 106 at mid mach speed?

Lots of hearsay about the MIg-31 but it's not so easy to find anybody who says they know it's flight characteristics for sure.

I promise you it can go farther than that. Top speed in level flight is just a bit over 0.925M. In a shallow dive it has exceeded 1.0M.

I worked on the FMS performance calculations for the G650 for a few years.
