Well, it is simple, but it is also a practical ban to forced marching for characters without a Con bonus or Endurance training. As most parties will have at least one such character, it effectively makes the option untenable in general, I'm afraid.Capn Zapp, yep that section is missing even after being specifically called out in the PHB. I like your skill challenge approach! For those instances where you just want a quick resolution, here's my house rule based on drowning/starving.
FORCED MARCH
Normally a character can’t travel more than 10 hours in one day. An additional hour of travel requires a character to make a DC 20 Endurance check. Success buys the character another hour, while failure costs the character a healing surge. Then the check is repeated at DC 25, then DC 30, and so on. A character without healing surges who fails a check takes damage equal to his level; at 0 HP the character collapses. A character cannot regain healing surges or hit points lost to a forced march until she or he takes an extended rest.
A DC 20 check is close to impossible for a starting character without a Con bonus or Endurance training, and it doesn't take many hours until the check becomes truly impossible for everyone.
I note how DC 20 isn't supposed to be a Moderate skill check until level 18(!) according to the (errataed) DMG.
Frankly, you could simplify this to say "for each hour past the ten you press on, each PC lose a healing surge". At least this is fair to characters whose class discourages a high Con or skill training in Endurance.
Or perhaps simply state you can't walk for more than ten hours period.
I don't say this to be snarky, but because I feel losing one healing surge each hour is (in my mind) an awfully high price to pay for the relatively small benefit of extending your rate of travel by 10%.
Thanks for sharing though!
