On-site registration will begin at 9 a.m. today, followed by a 3.5-mile walk around the lake and a community resource fair from 11 a.m. to 1 p.m.
Participants will receive a free T-shirt and be able to enjoy live music, dancing and children's activities.
The resource fair will include more than 25 booths from various city programs, according to Estelle Clemons of Oakland's Community Action Partnership.
She said the agency hoped people who might be hesitant to walk into a city agency would be more comfortable finding out about the city's programs at the resource fair.
"We wanted to provide another entry point for dissemination of information," she said.
Information will be available about the Head Start program, free transportation, re-entry and second chance programs, subsidized work and education, low-cost insurance, food banks and food stamps, low-cost bank accounts and more, Clemons said.
She said people in all socio-economic brackets are encouraged to attend the fair and learn about the different programs.
"Everyone knows someone who has fallen upon hard times," she said.
