Fundraising models differ from event to event, however the purpose of a charity rally from the organiser's perspective is to organise an event that will generate funds or direct donations which can then be donated to charitable causes.
A pure charity rally involves participants raising money for charity, which is paid directly to the nominated charitable organisation. Controversy exists over some other forms of charity rallies, whereby organisers fund their costs, and sometimes their lifestyle, from charitable donations, while holding out their organised rally to be a charitable one. Purists consider this to be a form of charity fraud.
In other forms of charity rallies, teams have to compete in a motorsport event and deliver goods, services and other direct aid to the communities they visit during the rally. The world's largest charity rally, the Budapest-Bamako follows this model. Different schools of thought exist with respect to the type of aid model that a charity rally should support.
Ultimately, the choice of aid model follows the organisation's business model which, so long as funds are raised in accordance with ethical standards such as those set by the Fundraising Standards Board,will ensure that the charity rally fundraising concept will continue to grow unabated.
