Either the food the DK is carrying is heavier than the hero's food despite looking to be about the same amount, or the DK has extra weight equipped or hidden in his inventory somewhere.
[color:"yellow"]He's indeed carrying much more food than the hero, that probably caused the problem, I dropped some food down in the battlefields too.[/color]
Is your DK using a two handed weapon? He can still pick up a shield and have it get put in the inventory slot, but greyed out (disabled) so it is harder to see. That may be adding extra weight.
[color:"yellow"]Yes, he is using a two handed sword, but I got ridd of the shield some time ago, because it was too heavy and he couldn't use it anyway[/color]
Thanks for responding, I hope he will run again now <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
