Some of this is probably correct. My understanding is that it would be possible to use donations to pay for expenses of his fun raising (travel, race entry etc.)
Someone should dig to see if he actually set up a 501(c)(3) for worldrecordrun. Hey, newspaper reporter, are you still reading this thread and want to run a quick lexis search?
Wouldn't we all like to deduct our running expenses, particularly if you have a travel habit (for running or any other purpose) and wanted a nice way to deduct all of your airfare by kipping a race in the place you traveled to? Actually, for that, it wouldn't even have to be a charitable organization, though if it didn't have much income, there are limits on how long he could continue to take a loss through it. That'd be interesting.
