It would be a crappy skill in 3.5e, because such challenges were among the easiest (and cheapest) things to remedy through magic. I believe 4e gives us some kind of magical bread that addresses the hunger issue, so we may be in the same spot in 4e.loseth said:Perhaps...
--force march
--hold your breath
--ignore hunger/thirst
--run for longer
--swim or tread water for longer
--sleep in armour
But if that's all there is, I'm thinking it'll be a pretty crappy skill. So, what other uses for this skill can you think of?

I'm thinking it will be used for a lot of the things that Constitution checks were used for, like others have said. But it feels strange having a "skill" called Endurance....
