- Hundreds of local residents are joining forces to fight lung cancer, united in the belief that surviving lung cancer should be the expectation, not the exception. These every day super heroes will be meeting at the San Diego Free to Breathe 5K Run/Walk & 1 Mile Walk at Embarcadero Marina Park North on Sunday, August 7th. All proceeds from the event support Free to Breathe, a nonprofit organization whose vision is to double the lung cancer survival rate by 2022.
