 Ultimately, the choice of aid model follows the organisation's business model.A business model from which the organisers make no profit, either from the entry fee or the funds raised by teams, is the most valuable model for the community.This is a model used by Charity Rallies, a volunteer based rally run by a UK registered charity, with teams paying a £300 entry fee to cover administration costs for the Mongolia charity rally (with the excess being donated to charity), and the teams raising £1,500 for charity, in 2009 and 2010.
