Walk Now for Autism, North America’s largest grassroots autism walk program, is Autism Speaks' signature fundraising and awareness event, taking place in communities across the United States, as well as in Canada and the United Kingdom. Powered by volunteers and families with loved ones on the autism spectrum, this successful grassroots fundraising effort not only generates vital funds for autism research but also raises awareness about the increasing prevalence of autism and the need for increased research funding to combat this complex disorder.
