In addition to the founders' official charities, we applaud the efforts of our participants who have raised hundreds of thousands of dollars in support of many wonderful and worthwhile charities. Over 50 charities have benefited from our athletes' participation in the Grand to Grand Ultra and Mauna to Mauna Ultra since 2012. We list below the charities which will benefit this year. We encourage you to click on the logos to visit their sites and become familiar with these causes.
