A German proverb says that "charity sees the need, and not the cause." Sir Francis Bacon added that "in charity, there is no excess."
While I agree with the Germans, I must certainly differ with Sir Bacon. I think this kind of charity event is excess. The website even invites would-be participants to break the existing record of 8 hours and 30 minutes. Imagine that!
There are certainly other ways of helping AIDS/HIV patients and advancing women's health initiatives.
