A crowd estimated by police to be more than 100,000 turned out early Sunday to support the Fundación Anna Ross and its fight against cancer.
Many participants were cancer survivors or were members of a family who had lost a close relative to the disease.
Anna Ross was a well-known physician and political figure who died in 2003 after a long fight with cancer. Her family created the foundation as her legacy to provide psychosocial support to cancer patients and their families. The foundation also provides nutritional support, training, wheelchairs, wigs and turbans
Most who have been supporting by the foundation are patients of breast cancer, colorectal cancer, prostate cancer and lung cancer. Such diseases combined are the second leading cause of death in Costa Rica.
Sunday was the 11th event that was a two kilometer walk, a 5K run or a more challenging 10K run. The routes ended at Parque la Sabana. Participants were accompanied by bands, including musicians from the Colegio Tecnico de Puriscal.
