Split Personality?

[Sauron the White]

from Alatar

Arguably Eomer may not have been the best judge in this matter. And again, as I've stated, these three are the best of the best at the top of their game.

I wonder if Eomer had access to the rules and regulations issued by the equal of the Middle-earth Olympic Committee? Without a doubt, records set with the aid of substances such as lembas would have been invalidated in much the same way as the recent biking scandal in Paris. Superhuman individuals hopped up on lembas with muscles which do not process gylcogen - or even need it - yeah, Eomer did not know what he was talking about.

I think the point that you're missing, STW, is that it is possible for the dwarf, man, and elf, but it also is very difficult. Tolkien never wrote that it was easy, and Jackson never protrayed it to be. It wasn't an everyday occurance in Rohan for someone to run so far in just three days. These three hunters had motivation and a long journey behind them, giving them will power and endurance, giving them the ability to do something that was uncommon and surprising to Eomer.

Sounds to me like you want it both ways here. Eomer was right in that it was an achievement for the ages even though
a- each of the three was in some ways non-human and had special physical gifts or abilities beyond the normal possessed by humans
b- the normal rules about running, glycogen and muscles do not apply to the three
c- they were hopped up on a special athletic performance enhancement substance which gave them prolonged strength, vigor and power
d- they may have some divine intervention assisting them as well as some here speculate that Eru himself willed it

Nope, sounds to me like its either they did something that is pretty near darn impossible or what they did was vastly overrated by Emoer who was judging them by his own standards.

I really do not think it is fair to try and have it both ways.
