In order to be accepted to the event competitors are required to pledge and raise the minimum sponsorship set by the organising Committee. Most competitors, however, raise considerably more.
From 1989 to 2018, the Rhino Charge has raised over KES 1 billion. In order to ensure that the funds raised by the competitors go to conservation, the Rhino Charge itself is organised mostly based on in-kind support provided by many volunteers, event sponsors, guard post sponsors and raffle donors. Since 1989, the funds raised have been used for the construction of the Aberdare Electric Fence and supporting conservation activities within the Aberdare ecosystem. With Rhino Ark formally committed to supporting conservation in Mt. Kenya and Mau Eburu ecosystems, funds raised are now used for fencing these two mountain ecosystems, in addition to maintaining the Aberdare Electric Fence and engaging fence-adjacent communities in conservation.
