Organizers have announced plans to circulate petitions at the finish line of a half-marathon due to be run Sunday morning and stage a march and rally in the afternoon. Organizers have until September 26 to collect 101,597 signatures, or 15 percent of San Diego’s registered voters.

Proponents of the recall say that more than 800 people have signed up to volunteer on behalf of the recall drive.

“We’re so gratified and encouraged by the enthusiastic response to our call for volunteers,” Michael Pallamary, a land use consultant who filed the petition to recall Filner, told Fox5SanDiego.com. “This is a tremendous grass roots undertaking — truly the people taking back their government from an abuser who has betrayed San Diegans, demeaned women and who can no longer lead our city.”
