In 2022 the Charity Challenge will be a full, three day event, with practice and some qualifying on the optional Friday session. Since the first Charity Challenge in 2004, the charity rides program has raised over $1M for the Sonoma County charities, and the Saturday night part dinner and auction, assuming COVID restrictions have been lifted, are as fun as parties can get.
