It has little to do with "giving". This is a business. Businesses buy sponsorship from the WTC and in return get significant exposure for that sponsorship. I am not sure which sponsor directly supports the prize purse at IMH or wether a group of the top tier sponsors all put money in a pool. However, that is where this money would/should come from for performance incentives.
Interestingly, IMH has taken the route of not allowing a title sponsor for the race - like many other similar events( The ING New York City Marathon, The LaSalle Bank Chicago Marathon, Subaru Ironman Canada . . and so on).
