SAN DIEGO (CBS 8) - This weekend, hundreds of San Diegans put on their walking shoes to raise money in the fight against multiple sclerosis.

Sunday, the Southern California Challenge MS Walk wrapped up in downtown San Diego.

On Friday, the 50-mile three day walk kicked off in Carlsbad.

Dozens of people who took part in the walk are battling the neurological disease of the central nervous system.
