More information on donations and fundraising is available on our fundraising page.
Unless otherwise requested by the donor, all team and other fundraising proceeds raised through the Mercer Island Half go to The Cancer Patient Assistance Fund at Swedish Cancer Institute, a national organization whose mission is to empower local communities to promote prevention and early detection of colon cancer and to provide support to those affected. After event expenses are paid, revenue from registration fees goes to several charitable causes supported by the Foundation of the Rotary Club of Mercer Island. See the Rotary Club of Mercer Island website for more information.
Donation checks should be made payable to MI Rotary Foundation, and mailed to MI Rotary Foundation, PO Box 1, Mercer Island, WA 98040, or dropped off at the event.
