Just how far can a human travel under his/her own steam, with or
without mechanical assistance in 24 hrs?
I am not talking about any un human powered method of travel.

What you do speaks so loudly that I cannot hear what you say.

I suppose it all depends on the circumstances, altitude, heat, humidity, climate etc
If they are in free fall then quite a long way :-)
The average walking speed is what...4-5mph ?...and then sprinting 25mph ?, jogging 10-15mph ?....assuming no breaks for drink wee wee and poo poos :-) then I would hazard a guess at somewhere between 100-150 miles before they collapse and die !!
This is one for daveshorts...he just luffs to work these things out !!

Hummm, so how far could a nappy wearing roller skater travel?

Thinking a little more, a bicycle could have some sort of electricaly
driven system that is charged on down hill sections, that would be in
my (rules) as long as there was no energy in the battery to start with.

how about a car or then again a rocket[:D]

I think those speeds are for a fit, not an average, human being.
About 3-4 mph is average walking speed.
What you have excluded is the distance that might be covered by use of a bicycle (Robin did allow for mechanical aids, so long as the sole source of power was human). I think bicycles are probably one of the most efficient forms of long distance human powered travel, particularly if you are travelling on paved roads (and even more so if you can design proper streamlining around the bicycle).

Start: US 89A on AZ/UT border
Finish: UT Hwy 150 on UT/WY border
382.9 mi, 21:47, 17.67 mph
In other words, 346 miles in just over 23 hours on a bicycle across Arizona, or 383 miles in under 22 hours across Utah.

You didn't mention anything about hills before – the best way to go for an endurance record is over flat ground.
Electrical energy storage systems are a nice idea, but in their present level of development, I suspect they would carry too much of a weight penalty to be worth the advantage they might bring.

Wow, AS, 383 MILES, that would take some beating.

Yes and i guess any charging would slow the bicycle, thus negating any
advantage.

So, what counts as he "stopped" after those 24 hours? After he took a break? After he collapsed? After he died?

What about a canoe and the right river at the right time? Could that beat that record?
Or maybe a wet glacier in Greenland.

I think the record must be around 660,000km in 24 hours.
Set by: Every astronaut on the ISS (orbital speed 7.66km/s).
..he doesn't even seem to be working particularly hard!
Other astronauts orbiting at a lower altitude than ISS would have traveled even further.

In 24 hours I will have traveled about 12000 miles because of the spin of the Earth.
If I was at the equator it would be about twice that.
I'm fairly sure that the solar system is doing about C/10 in orbit round the centre of the milky way.
It turns out that another interesting question is which human has travelled the least distance in 24 hrs?
