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[]

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).

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.
